Camshaft deviation specs for '01 3.2L

[JFP in PA]

Porsche has used both +/-4 and +/-6 degrees, with the latter being the most common on the M96/97.

Yes, you are definitely out of spec; cause could be a number of issues ranging from the tensioners, chain paddles (including the ones between the cams of a five chain motor), chains themselves, and/or the VarioCam components. Unfortunately, the only way to know what is causing it is some extensive diagnostics checks, which could include checking the actual mechanical cam timing itself, which requires some specialty tools...........

What's my risk being out of spec like that? It seems to be running great...

Problem is that whatever is causing the car to be out of spec is going to get worse, not better.................

Any way to find out short of a tear-down?

Unless you have accumulated plastic shards in the oil sump, no. And even if you have got shards, you still don't know which pads/paddles need to come out until you look at them. Quite often on five chain motors the smaller paddles between the cams are the issue. But you still have to look.............

holy crap... and I bet you can't find out which chain is the culprit just by looking at them. This is not good news... I've had it. I'll sit and watch this thread for a bit

I changed the oil & filter this weekend, nothing in the filter except a small glump (technical term) of what looked & felt like white sealer. It was still pliable, maybe a little over 1/8" long & smaller wide. Oil was clean with nothing in the bottom of the catch basin. I guess it's time to pull out the Bentley to see what I'm in for.

Madmods, this will be a DIY project; I haven't found much that wasn't on this thing!
