    Valve cover and intake plenum came back from powdercoat today, followed by 2 hours of hand sanding the raised lettering.

      Those look nice.

      Was the sealing surface for the oil cap bare metal originally or painted ?

        Can we see pics of the M3 as it was and is now? Where was this car found in Maryland?

          I don't know. I was planning on flatting out the texture on the sealing surface but leaving it black.

          No idea where in Maryland it came from. This is how he got it.



          The vehicle was completely stripped, media blasted to bare metal, all bodywork needed carried out, and then painted flawlessly.



          It sits in the roped off corner in the showroom of his body shop (Imperial Collision) so clients that come in can see it be worked on and watch it from a safe distance.

              Picked up a harness snippet from a 325e parts car over at my buddy Thad's house today, a few wire colors vary but the AFM and Barometric Pressure Sensor connectors are the same. Carefully spliced it into the M3 harness to repair the lopped off section and pulled it back onto itself for as close to a seamless repair as practical.

                What are you using for the rubber wire loom. I can't find anything aftermarket that matches that.

                  The original!

                  If you heat one section with a heat gun it becomes soft and supple so you can easily force the non heated section inside the hot section.

                  Once cooled its pretty well fixed in place.

                      Good to know! Those look fantastic.

                      I'm looking to replace the loom on mine for the oil pressure sensor wire running in front of the timing belt, it's old and cracked, I don't believe I can coax any more life out of it.

                      Aftermarket ones are corrugated stuff, or the weave, both are acceptable, but far from oem.

                        Heat shrink tubing would be a close match. Would make it easy to slip on as well.

                          All of the hardware came back from plating today. Turned out very nice for 31 year old rusty crap.




                          I shall be able to start reassembling some of the vapor honed parts now that I have hardware. Now if I could just remember where everything went, that's the trick.

                              I'm most impressed by the combination of speed AND quality. I firmly believe that anyone (given enough effort) can do a project either quickly or with high-quality workmanship. To pull off both at the same time is impressive. It means you have built a great network of guys who share the same fastidious attention that you do, which is NOT easy.

                              Love the pictures.
