W124 Timing Chain Seal Change M104 3.2 Help Required

[SebringMan]

Right, my front timing chain cover seal is leaking on the W124 (a 1995 E320) and TBH I need to change it.

The procedure from what I can see looks straightforward except one thing; stopping the seal from rolling over or ripping as the timing cover is put back onto the engine. Some people recommend greasing the seal, others say to trim the seal to aid assembly.

My question to you folk here, is, how I can not destroy the new seal when I refit it? I guess one way is to remove the dowel pin but I'm semi stumped, but I cannot leave it as it is either!

So, fire away folks . I think mine has the M104.980 engine. It's definitely an M104 however .

Thanks for posting. I’ll clean the area first and see if I have these symptoms. If I do..... easy fix.
