Hey, thanks for the tips. The car is up and running already. I had never done this repair on a M104 and didn't realize the chain guide pin should be removed while the timing cover is still installed. What I did was thread a bolt into it (didn't know it was threaded, learned that here on the forum) and use small combo wrenches as spacers, then gradually tightened the bolt to pull the pin. It came out with a "pop" sound. Once the pin was removed, everything was very easy, just like on the M103. Installation of the pin was rather easy, too, and was assisted by the hex plug that covers the access hole.

I'm familiar with procedure for properly prepping surfaces and adding just enough sealant that it doesn't ooze out into the engine (I used the MBZ black sealant). I also installed the U-seal dry as it should be - the previous butcher somehow thought using black sealant all over the gasket was a good idea, and I had to clean out the U-channel. I just put a dab of black sealant on each end of the U-seal and put a light coat of oil on the top to assist in assembly. All went fine from there on out.

But thanks for pointing out that information as I'm sure plenty of members here can benefit from it.

Oh, and thanks for the offer of help too. I may take you up on it someday!

Regards
