So after I got my 740i from the body shop, I knew I still had to deal with the power steering leak where the fluid would just drain right out.
Took it straight to my trusted German indy to figure out what was going on.
Initial diagnosis was a failed high-pressure power steering line (pump to steering gear). Made sense. But once they started tearing into it, they found the real issue — both engine mounts were completely
collapsed.
It was to the point that the engine was
sitting on the steering gear and was ultimately the reason that the high-pressure steering fluid line broke.
Looked really bad and oil looks to be everywhere, which is coming from my valve cover gaskets.
I ended up having to replace Motor Mounts, Power Steering line & Power Steering pump (and serpentine belt) itself as it locked up internally and failed due to running dry between the time it was at the body shop to driving it home and then to the German Indy shop.
That trip to the shop costed me close to ~$2,000 but since I no longer have my Acura anymore, allocating funds to get major work done on my E38 wasn't a problem.
Next thing was I got around to fixing my parking brake handle that broke off a few months ago. DIY'd it ofcourse.
Took me almost two hours to do, but I got it done.
That Bowden cable was B*#%$ to take off the old handle latch and put back onto the new handle. Not to mention having to pull apart the lower dash and what not.
The space is tight, the Bowden cable has almost no slack, and I felt like I needed three hands to hold the panel, tension the cable, and latch it at the same time.
But many thanks to the BMW Forums archive for the tutorial on how to do the repair.
Next Up:
Front Suspension refresh, Valve Cover gaskets, and got to diagnose what's causing this low idle stall issue every now and then where the car will stall out at low rpms mainly when idling.
So far I am thinking Camshaft Position sensor or crankshaft position sensor. Perhaps I replace both as a safe measure.
Yes, you are braver than the Marines!
