Hi all,

My '93 190 2.3 is at a local shop, getting it's head gasket replaced after finding oil in the coolant.

I've used the mechanic before, and he's competent, but not a Mercedes mechanic per se.

After buttoning things up, mechanic ran and test drove - and the CAM BROKE!

He replaced it, and the replacement CAM BROKE!

What would cause this? I looked at the head and Cams with him, and nothing looks awry ( of course, I am NOT a mechanic ) but he's a bit stumped.

Any help much appreciated, as at this point I'm soliciting expert advice from people experienced w/ Mercedes in particuler.

Thanks in advance,
Mark
