Thought I'd start a new thread and post updates and pictures as I progress. Go to this link to for the beginnings of this project:

I'm still in the 'cleaning everything real good' stage, which is turning out to be a very large project just by itself. I just can't stand putting something back together dirty, even if it takes a lot of work to get it clean.

The previous owner replaced the fuel injectors, but I didn't know where he got them from. Then I happened to look in the bag of the old, original injectors and I found these:

Which was a pleasant surprise as I have heard nothing but glowing reviews about FIC, so I know the injectors are good quality.

Here are a few before and after clean-up pics:

Fuel injector rails & IH's before

Fuel injectors & rails after (also installed the new fuel pressure regulator, which came with the car)

IH assemblies after

Plenum, throttle body & airhorn before

Plenum after

bdw18_123 · 09-10-2009

Throttle body & airhorn after

Alternator before

Alternator after (I painted the aluminum case halves with paint that imitates new cast aluminum look, cleaned interior of alternator also)

The plenum, IH's & airhorn/throttle body cleaned up pretty good. There are some stains I can't get out and the top of the throttle body has an area where the coating is missing, but they look much better than before.

That's it for now.

Ben:

Looks like she's cleaning up really nice.

One small thing though...
There is a ring of special sealant called "DAG" around the blades of the throttle body that seals the blades and helps with the idle.
Hopefully, you accidentally didn't clean it off too...

New heater core is relatively cheap. The install is what sucks. You still have a lot to remove to get to it.

Keep making progress. Just don't let it go dormant for along period of time.

That makes my head hurt just looking at all of those parts. I can only offer encouragement.

Keep up the good work, there's an end to that project someday.

Heck of a job Ben!!

Continued work on the dash pad. Part of the hold down tab above the headlight switch assembly was broken...

...so I cut out a small piece of thin aluminum sheet metal, drilled pilot holes in the remaining part of the plastic and attached the aluminum with screws (I have scraps of aluminum sheet metal from when I used to work on aircraft).

After I cleaned and detailed the dash pad (including the carpet section) & gauges surround piece, I reinstalled them.

Windshield interior pieces have also been cleaned & detailed.

Cleaned and reinstalled DIC & A/C control head.

Cleaned and reinstalled headlight switch assembly.
