1982 300D Engine Knocking After Injector Cleaning

Hi Everyone,

I just finished fixing one problem only to get myself into another :-). I tried to install some of the new monark nozzles from mercedessource. I tried to be very careful and clean when reassembling the injectors after replacing the nozzles and thoroughly lapped all the mating surfaces with fine sand paper as described in the guide.

One thing I was not able to figure out is how to remove the old crush washers from the engine to replace them with new ones. Because of this I left them there. Any tips on how to remove these would be much appreciated as they seem pretty stuck in there and there were no hints in the manual I received.

123 Mercedes 300D Turbo Oil Return Gasket Replacement

Help! So I am in the middle of changing the gasket for the oil return pipe that goes from the turbo to the top of the oil pan and I thought once I started I would figure out a way to get the whole pipe out, but I am about 1/8th of an inch of clearance from being able to get the top half of the pipe off. Is there a secret to this? I searched the internet and the only tip I could find is to remove a heat shield that would give a little more clearance but there must be some further tip as I contemplated that but it didn't look like it would help.

1982 240D too much inside tire wear ??

Hi,

I have replaced everything steering and suspension wise except the steering box(which does have some play) and had the car fully checked over and aligned. I am getting very server tire wear on the two front tires on the inside. The tires don't even have 5000 miles on them and have already been rotated once. I brought this back to the shop and they said oh these old mercedes just have the camber set which tilts the tire and there is nothing I can really do about it.

1985 300D Loosing power on WVO

I recently did the conversion to WVO with the mercedessource kit and things were going well. As I started adding more WVO to the tank and got up to around 90% WVO and 10% Diesel I noticed the engine starting to hestitate after running it for 10-25 minutes. It began by hesitating at 75 on the freeway, every five minutes it would get worse and worse until finally I could only get the car up to 25. The filters looked fine so I tried adding 5 gallons of diesel fuel and the problem started to go away as the diesel got mixed in, acceleration came back.

1984 300TD - What to do with heat-damaged door frame surrounds?

This seems to be an overly common problem on the 123 chassis, yet I can't seem to find anyone else talking about it.

The interior color-coded plastic surrounds for the doors and hatch are all warped and buckled. Seems like every 123 I've seen that wasn't always garage kept has this problem.

My question is, what do most folks do about it? Rip it all off and leave the painted metal showing?
