Hey Team,

Looking at documentation, am i right in saying that the pins on all 4 camshafts (2x each bank) basically need to line up with the little hole on the sprocket? Double checked mine, and they're all out just a little when i rotate the crank to 45. Is there a tolerance that's worth having to get the valves checked? A piece of timing chain guide broke so going to replace the guides. Any thoughts much appreciated ?

I only have first-hand knowledge on the 6's and 12's. Don't like to see questions being unanswered.
Luckily, the archives are full of good stuff. I recommend you bookmark this thread and read all posts by "Mercedes Mechanix"


Good luck!

Thanks mate - with the linked, it seems that the cam lobes are positioned differently from mine. Even though pin seems to be matching in location ? i suppose if anyone had a picture of snag they're supposed to look like that'd be helpful, Mine for reference

Just bumping this - just trying to figuring out if my alignment is the same as others with the same 119.971, if if my pistons / valves are buggered and have touched.

Just following up - i seem to be able to rotate so that the lobes line up with everyone else's image, however it have to turn it past 27 degrees on ten crankshaft.

Guessing it's fairly out of time on this one? Since i thought it had to be 45 degrees to get to this point.

Someone with a V8 will correct me if I am wrong, but the timing mark shown on this image


appears to be at 270 degrees.

This is way, way out of 45 degrees where the holes and the camshafts should align.

If indeed 270, I'd be very concerned about piston/valve interference.

Just bumping this up - if anyone with the M119 can confirm that the cam lobes are meant to be in the position here, then I can see how aim going to attack this. Might need to pull the full front timing cover to see the dealeo.
