BMW newby checking in

[John Prophet]

Well I think I will go ahead and pull the head after all.

[John Prophet]

Alright, got the bmw up on the lift today.
Rear exhaust gaskets are gone, not there anymore. So theres like a 10$ fix, needs an alignment done too. I did discover this car has a magnaflow after cat exhaust on it.

The rear shock is shot as well, doesn't appear or sound like there is any fluid left in it anymore.

The guibo unit, or driveshaft balancer blah blah is on the verge of disintegrating as well. Kind of figured that since it had a slight vibration at certain rpms.

So I ordered a new guibo, can get the exhaust gaskets locally as well. Do them both when the guibo comes in.

Then when I got home I was greeted by my new valve cover gasket! So I got the valve cover off to be un pleasantly surprised.


Do you see it???
Let me zoom in for you,

See now?
2 snapped rockers!
Amazingly enough the car still ran, and ran pretty good honestly.
So I will order 2 more tonight, already looked up how to pull the assembly out.
So will change those out soon as replacements come in. Then take it back out to the left and do the guibo and exhaust gaskets.

I will say right now, I don't have the ability nor the desire to pull the motor or the head at this stage to do this. So while its going to be tight, I am 99% sure I can in fact do this with the motor still in the car.

I am going to paint the valve cover, got it started already. Degreased it, roughed the surface, hit it with a primer, then red high heat enamel. Once that all cured up Ill go ahead and sand the paint off the bmw logo, and the bars on the calve cover.

joy joy

And that's all I need to correct this issue?

Rear Shock Mount

most people install a shock mount reinforcement plate to take care of the weak point. See below.

That sure does thank you very much!
Get that guibo thing ordered and get the exhaust and new guibo thingy sorted!

I snapped a pic of that rear shock, crappy picture for sure! The shock housing doesn't look wet, so what part do I need to correct this?

That one has a conventional flex joint!
Yea Im going unbolt everything replace gaskets, and try and just weld in a piece of pipe in place of the flex section.

[Dakotademon7]

I see what part your talking about. Looks like you may need the whole pipe or get a good one from a junk yard and use the band style clamp to connect it after cutting out the old section.

[John Prophet]

awesome, still need to find the correct rear exhaust donut gaskets, not hangers or isolators.

And need to know how you guys fix that accordion in the mid pipe/ cat unit.

[Dakotademon7]

Wait the rear exhaust gasket is plastic or rubber?

Im doing the valves this weekend, .010" correct?

That's correct on a COLD engine.

Actually traded my 95 gmc Z71 for it, went from 8 mpg to a whole lot more!

Reality was both were worth about the same, but the guy didn't want the stereo in the GMC, so I did get to keep all that.
Intake boot was shredded,
the 90 bends off the throttle body need jb welded in,
the ICV was gunked up pretty bad,
Valves need done (this weekend if everything goes as planned)
Passenger rear shock is messed up, the bar goes right through the top of the mount. Honestly not sure if I need a new rear shock, or a new top plate.
And the rear tires are bald,
Oh and the accordion flex pipe is leaking, (exhaust taped for now) And I need new doughnut gaskets in the rear of the exhaust too.

If you guys know what gaskets I need back there would help me a lot, as well as how you guys are fixing a leaking accordion flex pipe?

You can pick up almost anywhere. Bluntech, pelican parts, etc.

[Dakotademon7]

Welcome to the forum. Really good deal on it.

[heatmakerz]

1200 for that is a decent price. Next thing to focus on would be all maintenance (general as well as preventative) the previous owner neglected to do. Good pick up.

[John Prophet]

Its the little accordion shaped flex pipe right under the headers, right before it bolts to the cat/ mid pipe. Those gaskets that bolt from exhaust manifold to mid pipe are still good, but the rear ones are shot too.

Ill snap a pic here in a few.
