85 300D progress

Well, I finally got the head all cleaned out, refaced the valves and seats, and finally lapped them all in yesterday. I pulled the head first just to investigate. I am now in the process of pulling the rest of the engine. The manual sais to pull the engine and trans as a unit, so I figured I would try it like that. Got everything unhooked any ready to go except the two allens for the engine mounts. I did not have a set of metric allen sockets at home. When I chain it up, what area of the engine is best to get the correct balance in order to have the engine tilt up in order to get the transmission out? I was thinking maybe just slightly forward of the middle of the head.

The FSM says to extract the engine/transmission at a 45° angle.

I am pulling the engine because I am going to rebuild the entire drivetrain of this car. The car used to be my commuter but after a year of commuting from Stockton to Sacramento I was burning a gallon of oil a week. Ever since I have owned the car I could hear a slight little knock. It wasnt extremelly loud, but I could hear it blended in with the normal engine noises. I thought at the time that it was probably a worn wrist pin or rod bushing. I decided to drive as long as I could. After I started to rapidly burn oil the level got away from me a few times. After a few months the knocking got very loud. I suspected a bearing, but I always had very good oil pressure. So I pulled the head to do some investigating, I wanted to see if there was a problem with the head or maybe a cracked piston. After getting the head of the only thing I found was alot of valve guide wear, and #5 and #6 cylinders had some scoring. The scoring was not to deep, it should clean up and I will run oversized pistons. But I decided to just rebuild the the whole thing and be done with it. It has about 230,000 miles, I know some go longer and I am not sure if I am building it before its time. But I figure if I do the complete drivetrain now and take proper care of it, I should be good for another 300,000. After it is all back together I plan on repainting, installing the euro lights, and installing bigger rims. I am still undecided if I should run 15" or 17" rims. I was also thinking of painting the car black and tinting the windows. The interior is all black, does anyone think this combo would be to dark? I know I could probaly find another 300D running for cheaper, but my dad gave me this car. He is still around, but one day when I unfortunately can't say that, at least I will still have his Mercedes.

Have you priced pistons? If the originals are still good, then resleeving will be much cheaper.

Edit: just for fun, I checked the price at Fastlane. 1st oversize 5 piston set: $880.69.

You said something about piston #6? Is this a 350? Seems I recall there is some stuff about them bending rods and wrecking pistons....

However, he's said in previous threads that it is a 1985 300D. Must be #4 and #5 with the scoring.

Ooooops, I did say #6. I did mean #4 and #5, I let the Cummins terminology slip again. Still getting used to the 5 cylinder.

The cheapest set of pistons I found were at importedcarparts.com, 1st oversize for $678.13

Well I chained up and pulled the engine and transmission. Now I need to split them and tear the rest of the engine apart.

Are the parking brakes released with vaccum? I could not release it and roll the car back.

The parking brakes are cable operated. You may need to look underneath the car real good and see if something is in the way of preventing them to release.

No just a little cable operated brake drum inside the rear discs. If all else fails, you can loosen the cable some more at the adjuster under the car. Driveshaft is above it.

Yeah that parking brake situation is weird. Never had any problems before, it always worked perfect. Maybe I have the trans. linkage or something hitting the cable.
