        I just read this entire thread and its pure win! I've recently been going back and forth on restoring my regular e30 (which I've already bought a crazy amount of parts for) or getting an m3. You thread give me so much inspiration to get an m but finding one like you did is proving difficult (at least for me) but never the less keep up the good work! I'm definitely in for more updates.

          Thanks! I saw a couple good ones on eBay go in the mid 20s. There was a also a slammed up, rusted shell (literally, no engine, no interior, no suspension or subframes) that went for $8k. Sadly I think the days of grabbing good ones in the teens are past us. But a good one snagged for in the 20s would be a great deal if it doesn't need a respray.

          Merry Christmas everyone. The M3 did ok this year as well :)

            Front Subframe

            Now the last phase of transition from car - to shell. Front and rear subframes.

            Detatching the steering linkage



            The one dusty bolt facing down in the middle of the picture comes off



            You can see how the bolt goes through the linkage to tighten the bracket down on the splines of the steering column.



            This picture shows where i detatched the front control arm "lollipops" in the bottom left. held on by two bolts




            The four lollipop bolts, the steering column bolt, and the nuts holding on the front shock mount shown here. Shock mount bolts coming off





            Driver side, courtesy of mr blurrycam



            Balancing both front strut/hub/brake assemblies in preparation for removing the front subframe. I pulled this thing all out as a single unit - i would not recommend this approach as it is very heavy and likes to bend in different directions. Anyways, doing things the hard way, i pulled it out - almost dropped it on my toes. Thankfully i was wearing my open toed sandals - safety first.



            Very very dirty.





            Various pictures of teardown - separating the strut/spring/brake/hub assemblies from the control arms, steering rack, and then detaching the control arms and steering rack from the front subframe. This is real "hip bone connects to the leg bone" kind of stuff, so i wont walk through in too much detail as it has been covered elsewhere. Some pics though...



            This is detaching the control arm from the subframe.



            Here you can see the bolt where the hub housing/knuckle assembly connects to the control arm, and where the control arm connects to the subframe. Also the rubber brake line is front and center here. Weighing OEM vs SS lines for the reassembly.



            ABS sensors - these are dirty but still working. Thinking about whether to replace - these fawkers are expensive ($80-120 each from what i've seen)



            Unbolted the steering column from the subframe. There she is - my pressure washer trigger finger was getting itchy at this point.



            Rest of it



            Steering rack out



            Strut/shock/brake/hub assemblies. Took the control arms off easily.





            Rotors are worn to say the least



            Thats it for the front!

              Rear Subframe

              Going a bit out of order here, but since i just posted the front subframe - here's the rear.

              Drive shaft to rear diff



              If i were doing this again i would remove the driveshaft before the engine/trans to keep the shaft from rotating while unbolting from the diff. As it happened here i used a strap wrench and elbow grease to keep it from moving while I worked at the bolts.





              After burning many calories...



              Center bearing unbolts easily



              And out she comes





              Detatched the metal brake line from the rubber brake line end section on both sides







              Here's the T junction where the single brake line coming from the ABS unit splits into left and right sections. I fount it best to leave this to disconnect until after the diff was out.



              Had to remove the parking brake lines as well. Think i covered this when i did my rear bearings, but its covered numerous places also.

              Two little spring loaded inserts.



              And unhook at least one of the two spring clips

              Then the shoes and brake adjuster come out easily.



              The little clip thing that activates the brake.



              It comes off easily, the two pieces pivot around that little dowel.



              Then the line pulls out the back.



              Then they unclip to swing free of where they mount to the sway bar link mounting bracket





              Speaking of rear sway bar links. The bushings on this guy were pretty shredded. I took the bar off separately from the rear subframe assembly.



              Bolt off



              Both sides - you can see the parking brake line holder here really well.



              And main rear swaybar bracket mounts







              This is where the balancing act began. I put furniture dollies under each brake rotor/shield to catch the assembly when i released the shock (and lowered it down gently using the floor jack.



              Once each was down, i could easily remove the springs.





              I supported the diff with my floor jack (the sides are still up in this pic, but you get the idea)



              Removed the rear subframe bolts



              And the bracket that goes between the subframe bushing houseing and the frame





              Released the rear shock mounts (the shocks were already hanging, just wanted more room to maneuver)



              Dropped the shocks



              Double checked that everything was removed/supported, and then removed the differential mounting bolt







              Be VERY careful if you do this, especially if by yourself. It was not as smooth a process as it looks here and this is a fair amount of weight to be moving around in an awkward position. Do this at your own risk



              Lowered the floor jack, and out she came.







              Shell status achieved (doors were empty here and trim off, will cover that next)

                I know exactly the M3 you're talking about, it's white. I believe its at a junkyard somewhere. Did it sell at 8k? If so that ridiculous. But alas I think you are right about finding an okay example in the teens.

                  Looks like it sold for "best offer". Even assuming that was $5k, still a lot. Such a shame to see one banged up like that-should be on the road.

                    wowo, zino! The picture taking and sharing on here takes just as much time and effort as doing the work on the car. Seriously, a huge thank you.

                    I can't believe (but at the same time not that surprised) BMW didn't make a junction on the electrical harness between the engine compartment harness and main chassis harness. When I was peaking mine I was praying that there was one, but now I know. That sucks! After doing a similarly extensive rebuild on a S13 240sx recently, I was very grateful there was a "Super Mega Junction" (Nissan lingo) that allowed the harnesses to be separated. Damn Germans...

                    Comment


                      The doors on the car actually required a fair amount of work to empty while cataloging everything, and not breaking anything.

                      First step was removing the rear glass. easy. two bolts in the b pillar, suction cups helped keep it from dropping





                      Next this clip had to come off, popped off easily with minimal force



                      This guy just pries off the back



                      These plastic pry tools are hugely helpful. I would never do this with a screwdriver - and they're less than $5 at Harbor Freight, so who cares if you break one - you arent scratching anything.





                      These are the clips on the lower window trim



                      Rubber was a bit tired. Going to be replaced




                      I was able to raise and lower the window manually fairly easily



                      The upper trim pries off with some moderate force in the front. Be careful and definitely use a plastic tool here. Be very gentle. I bent my passenger side trim a bit taking it off, but it should straighten easily with some careful re-installing. Driver's side came off perfectly - practice makes perfect.

                      This is the first clip



                      Clips all the way across the top



                      Little bend, should fix ok i think



                      The B Pillar trim comes off with some force pushing toward the front so it can clear the lip and clips.





                      So i tried to preserve the original moisture barrier when removing it... didnt go so well. The heat gun melted through it instead of loosening the adhesive. So I'll need new moisture barrier material - if anyone knows where i can find that...







                      These are the inserts the door tweeter speaker goes into. they just twist in



                      Window motor



                      The wire is zip tied up the front part of the door (from the factory). I cut the zip ties to free the cable. You can see both ends of the cable here as i have it disconnected from the window wiring harness.



                      Disconnected the motor from the gear mechanism. This lets the window move completely freely. One trick i used to keep it from falling was to put a strong suction cup on the outside of the window so that the cup would get stuck on the door sill, preventing the window from falling down.



                      Two bolts and the motor wiggles free



                      The casing shell comes off easily, but i stored the two together





                      Window down to remove weather stripping



                      Worked the weather stripping down from the top. There's a surprising amount of rubber down in the door itself.





                      Now the upper trim on the body of the car

                      Started prying here



                      First clip released. They are old and fairly small, so they'll probably break. Fortunately replacements are cheap and plentiful



                      Some of the clips came off with the trim, leaving scratches. Not a problem in this case with the respray.



                      Worked my way up. Remember what i said about it being ok to break the plastic tools...







                      Now for this guy.



                      I just drilled out the center of the old retaining pins.



                      Then its just prying



                      And removing all the mounting clips and gaskets - not much hope of getting these off intact.



                      I removed the clips so the body shop has a clean surface to work with. Plastic pry tools again



                      And a gentle mallet tap sends the clip flying





                      And then on to the door mechanics. I removed the four bolts that hold on the window motor (three on the left, one in the bottom right corner of the door)





                      Here you see one of the two tracks on the bottom of the window glass. To the right is the insert on the window regulator arm that goes into the track. Its already out here obviously.



                      Once the runners are out of the tracks, the window just lifts out.



                      Glass out



                      Now to take out the regulator and arms. These two nuts hold it on.



                      Collapse it down into the right position and it lifts out easily.



                      Here its where those two nuts went



                      Now, this is a cool shot. Inside the door! The bolt at the bottom holds on the front track that the rubber window stripping fit into.





                      There is a little hook at the top that you have to watch out for, the track has to drop down before it will release. Dont force it and break this.



                      Now looking toward the back



                      The other track is held on by one of the four bolts that held in the window regulator





                      The little black plastic plastic clip just below center in this pic holds a clip that holds a connection on the window wiring harness.





                      These two bolts hold in the door lock actuator



                      Disconnect the hook at the top



                      Then disconnect the electrics



                      Getting emptier. Left the hook for the lock actuator hanging.



                      Door hardware coming off



                      BMW gave you a metal bracket with your metal bracket so you can bracket while you bracket.



                      Then there's this goo



                      Rear bracket



                      How it all goes back together



                      And black rubber goo coming out



                      Door handle





                      Another hook



                      Wiring harness extraction



                      Tagging



                      Speaker wires



                      More mounting points for clips





                      Couple more zip ties



                      Powered mirror connection





                      The last wires are on the door latch box. This thing was not easy to get off. The bolts are torqued hugely tight and the screw metal isnt super hard. My advice, do what i did on the driver's side and use hand tools - a screwdriver bit paired to a long wratchet works very well. Power tools stripped the screws almost without fail. then you have to get mean and use dremmels, flat screw drivers, and force. Fortunately all came out nicely and new bolts will be used on install of course.





                      Door handles are easy



                      here's the back, inside the door





                      This little guy lives on the inside of the door and provides the bolt studs for the nuts to hold the door handle hinge.



                      Here's how it fits in



                      Unhooking more electrics. This looks like a sensor that sits on the door lock arm.



                      Here what it looks like after you remove the black box



                      One more bolt to release the high tech motion control mechanism... steel rods



                      How it sits in the car.



                      Misc door hardware









                      lock releases with this C clip









                      EMPTY DOOR!! Now, just do it all over again on the other side



                      And some organization afterward will help later



                      Remember what i said about door latch box hand tools? Proof from the driver's side...



                      And the driver's side lock didnt look so hot. Guessing this is related to the dent that is in the same location. Body shop is working that one out

                        Some misc pics of clips and retainers on the inside. gotta remember where these all go.





                        I think im pointing to where another clip goes...



                        Yeh, thats what it was













                        reading light mount



                        Holds the glove box, keeps it from going down too far



                        And in the engine bay











                        How the hardware goes back on





                        under the lip of the quarterpannel



                        Where the speed nuts go



                        Next up. Gas tank!

                            Man! I can wait for it to be sprayed and for you to start the reassembly

                            Comment


                              Fuel Tank/Lines

                              Hey Guys,

                              It has been a while since my last update because we just moved to a new house. More on that later, but for now. Here's the fuel tank:

                              Started where most people interface with their car's fuel system. Took the cap off, then drained from the plug you see pictured here.



                              Its wet here because i had drained some out already.



                              This container was nearly perfect for the job. Still had a good amount of gas in there.



                              Next i removed the covers under the rear passenger seat




                              The electronic sensor has already been unplugged here, but the fuel lines are still attached. The thing being held down in the middle by four bolts is the fuel level sensor.



                              No need to take it out to remove the tank, but here it is



                              Hoses Removed. Based on looking at the hoses underneath the car, the one that is above and to the right (if you are facing the rear of the car, not in the pic below) of the fuel level sensor is the main fuel sender line. The other is the fuel return line.



                              There is also another line that is in front of the hoses above. This heads over to the expansion tank.



                              I found this diagram VERY helpful



                              With those off, there's some underbody shielding to remove


                              And the lower end of the fuel filler neck to disconnect.



                              Next i started to remove the four (i think its four, could be more - its been a while) bolts that hold up the tank. They're all fairly obvious. There are still some lines on the driver's side of the tank that need to be disconnected but i did that with the tank partially lowered - either way works but it was easier to reach with the tank down.











                              removed the fuel filter



                              The sender pump and pressure regulator are easy to remove after the filter is out of the way.



                              Tank is partly down



                              Other lines i mentioned. I disconnected one from the tank and one further down.



                              Tank down



                              Many shop towels later...



                              The underside had a gunky coating on it. I'll probably respray it with a protective coating, but this one was coming off.





                              Now for those fuel lines (and a brake line)



                              These guys are LONG, and are held on by several clips along their journey from in front of the driver's feet to behind the rear axle.









                              Fuel lines terminate here. The line at the top connects to the return, and the other runs into the fuel absorber (which here has been detached from the sender pump).



                              the brake line continues on past the fuel pump assembly, then makes a 90 degree turn to run to a T joint in the middle of the car - where it splits into two lines to feed the driver and passenger side rear brakes. (dont know why the pic is all red... its not an instagram filter, just a taking pictures on your back under a car filter i guess...)



                              The T joint is right above where the diff used to be





                              I had to loosen the fuel sender pump assembly to get the rear brake line out, since i runs behind the bottom mount.





                              Once that's free, the rest of the mounts are just as easy. I've catalogued them all, but here's the end result. Lots of long lines to store.



                              Then there's the filler neck and tank mess. I believe i just pulled the filler neck out through the back of the rubber boot you see here (after loosening the bolt on the bracket that holds it to the body).



                              Neck comes off with a few bolts



                              Right above the fuel filler neck in the picture above you can see the lines running to the evap tank. These are normally covered by a shield which i have already removed here. Most were very easy to remove, but the one that runs to a metal condiuit that runs to the charcoal canister needed a bit more work.



                              Here's the charcoal canister line



                              A little more work and...



                              There's more detail, but thats the gist of it. At this point the car was pretty much a naked shell.

                                nicely done. you can still get those oetiker clamps no problem. The lack of rust on the lines and brake line tee is very cool :-)

                                you'll be replacing all the hoses right?
