Re: [MBZ] valve stem seals replacement
Ok, sorry The SDL is the only one I ever did in situ. It smoked on startup and had high oil consumption. After I did the new seals and chain, and switched it to M1, the oil consumption dropped to about the same as a new engine, and the smoking stopped. I used to lay a navy-type smoke screen with it before that. All other times, I put on seals as part of doing the head. I knew all that I was asking Glenn why on his car specifically...

Re: [MBZ] valve stem seals replacement
I would not advise doing your own, If your head needs guides, I'd leave that to a auto machine shop. If it only needs seals, then yes, you can easily DIY. A good way to find a good machine shop is to talk to they guys in the back of your favorite stealership. Find out who they use. Go to that one. The price of valve and seat grinding equipment is too expensive for use once every 2-5 years, or even a couple of times a year. Pull the head, check it, and if it looks good, take it in to a good machine shop that works on MB Diesels.When I pulled the head on the escort Diesel at 100K, it looked so good that I put it back on without doing anything but the new head gasket.

[MBZ] valve stem seals replacement
I'm still pondering whether or not I should attempt replacing the valve stem seals on my '85 300TD and, for anyone who is familiar with this job, is the assembly mandrel for valve stem seals tool (617 589 00 43 00) necessary or can the seals be installed without using this special tool?

Re: [MBZ] valve stem seals replacement
Do it. No special tools required. You will like the results, if you have smoke on startup. Rule #1 USE ONLY OEM SEALS! Rusty has em. OE seals are cheaper than FLAPS seals, and better. Take off the valve cover, remove the tensioner for the chain. Remove the valve followers. now come the choices: 1. You can leave the cam in place and work around it. 2. You can remove the cam with the sprocket wired to the cam. 3. You can replace the cam temporarily with a stub. What is handy is if you have access to a dead camshaft. Cut it off behind the first cam bearing. keep the front end. throw away the back end. What you have to do is work on one cyl at a time (two on a 4 cyl) with the piston at TDC. So, set #1 to TDC. You check TDC by pushing down a valve with a screwdriver. You should feel a solid thud as the valve hits the piston. This is necessary to hold up the valves while you work. You don't want to drop a valve in the hole. What is handy is if you have access to a dead camshaft. Cut it off behind the first cam bearing. keep the front end. throw away the back end. Wire the chain to the cam sprocket in at least two places, so it can't jump a tooth. If you choose #1, you are ready If you choose #2, what you want to do after the shaft is out, is keep the wires tight when you need to rotate the crank. You will take one wire out and put it in the next hole of the sprocket as you turn the crank. The sprocket will just ride on top of the chain guides. If you choose #3, pull the cam and replace it with the stub. When you are ready with #1 at TDC, Loosen the lock nuts on the valve stems, remove the nut, lock nut, rotator, washer, and spring. DONT reverse the INTAKE and EXHAUST parts. (or just do one valve at a time) Then, pry off the old seal, install the new seal and reassemble. After that, follow the firing order. They should all be done in about 290 degrees on a 5 cyl. Reassemble, set the clearances. Good luck.
