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.

83 300SD Window off track

Today I shut the door on my 300SD with the window down for the first time, and wouldn't you know it, now it gets stuck about half way up. I pulled the door assembly off but can not figure out how to get the window back in the track, it is the leading edge (towards the front of the car) that has jumped the track. Does anyone have some advice, or a direction I can look to get my window back where it belongs? Thank you in advance for your attention to my problem.

Early 126 300SD power seat switch replacement

n/a 1983 300SD passenger seat switch, the pin that controls the seat back broke off. The switch is hard wired and can not be removed by unpluging like the drivers switch can. I have opened up and replaced parts in the removable switches, but I am afraid to open this switch because I do not know what will happen when I pop the cover off, as I can not lay it on its back. Any Ideas or help are welcome.

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.
