More cleaning time today. I’m waiting for two big parts shipments which should be here Tuesday and Wednesday. It’s giving me some needed time to clean everything up as much as possible. I had left the EGR pipe to soak over night, and it came out great.
The slightly gunked pickup even came clean:
Then finished up the rest of the upper manifold and throttle linkage, which is where I left off yesterday.
I got most of the residual grease and dirt out of all of the linkage ball joints, and then re-lubed them upon re-assembly with this stuff
I wanted to avoid a thicker paste like grease to minimize dirt pickup, but if anyone has any better suggestions, please let me know. I also lubricated all of the pivot points with that stuff
I mounted the throttle clap trap back up. Is it not supposed to be perpendicular to the intake? Mine looks like its bent forward (towards the front of the car) slightly...
The lower half of the intake makes me think there was some sort of coolant leak in the passenger side rear corner.
That would explain at least some of the gunky bolts. I cleaned all that up as best I could, and then took a brass brush on the drill to clean out the bolt passageway.
Also found this little manufacturing mark near one of the bolt holes
Not sure if the milling machine initially hit in the wrong spot, or what.
Finished off the upper manifold by cleaning out the injector ports with a nylon brush on a drill, coated with simple green:
Clean as a whistle now!
Moved on to the injectors. All were just dusty and dirty. I have ordered new o-rings, so i wanted to get those off. Example photos from one of the eight.

I did note that one of the injectors has a crack in the pintle cap:
Anyone see any concerns with this? I’m planning on using as is.
Polished up the fuel rail too
Power steering stuff was up next:

Chased out the threads on the bracket bolts that go into the block. I think they had anerobic on em
Gotta love the original hose clamps, complete with MB star!
Attacked the rest of the engine bay plastics and miscellaneous parts.
Everything ready to go back in:
In my last remaining moments, I attacked the drivers side of the head & block.

Still needs some work, but starting to get there!
