Bernd,
Sorry to hear that. When I installed mine back in March, the marks were
right on. It is sad that Mopar is screwing up like this. It doesn't speak
well when you can't trust your own "mother" company's parts. Sad, truly
sad!
Guess I'll be re-checking mine in about two weeks. Will be installing
another cam. This time I'm going to advance it a couple degrees beyond
spec. Guess we'll see if the advance mark is where it should be. :'B

Subject: DML: Mopar Performance Timing Chain
People...PLEASE beware when installing the Mopar Performance DBL-Roller
Timing Chain!!
After everything was put back together earlier tonight, she was ready to
fire up again. She cranked (rather strangley) a few time but fired
up...VERY rough idle and the engine sounded like a diesel engine. We
immediately shut her down and tore down the timing cover...just to check if
the timing marks weren't quite "dead-on". Yup, they're right on.
Hmmm...maybe they're off from the factory...
We reinstalled the original factory set and found that it was off by three
teeth!! After a closer inspection of the crank gear (Mopar Perf), we found
that the normal "Ball Peen" mark was off and there was a VERY SMALL scratch
on the gear designating the alignment mark. We compared the factory and the
MP gear together and found that the scratch mark was actually the alignment
mark. Yes, it was mismarked from the factory!! (I'm an ex-mechanic and
have installed many timing gear sets without ever seeing anything like
this...and my neighbor who's an ex-GM Line mechanic checked everything with
me on install and agreed that this was mismarked as well.)
Please, be very careful when you install the new gears (if you decide to do
this yourself)...compare the old gear with the new one and don't just
"trust" MP to be accurate from the package.
We're checking the compression in all cylinders tomorrow to make sure that
nothing was damaged.
