Rusty cam gear sprockets
#2
How well do they fit on the ends of the camshaft? If the are very snug and have to go on straight to fit then i would say they are fine. If there is any noticeable wobble or tilt to the fit as they slide along the cam end I would say change them.

I would be concerned with the possible lubricating effects of the assembly paste both on the inside and, more critically, on the stepped end of the cam face. The consequences of a lubricating effect might mean premature loosening of that cam sprocket hub, and then hammering of the keyway and everything else that goes with the slight rotational movement. I think I'd just be using them clean and dry if they're still dimensionally OK.

I would replace these parts and install them dry,
any lubricant will reduce the clamping effect given by the cam bolt,
and thus cause possibly catastrophic damage.
It is common for these parts to crack along one of their shanks, with the corrosion on the inside of the spider bore it may have a place to happen.

Hey, not a bad price for a Porsche part. For the price of new it makes sense to replace it. I do have some discoloration on the cam noses as well, but noting to be done about that unfortunately.

I'm convinced! I'll replace them.
Mrmerlin any special reason for acetone? Will denatured alcohol work? I have that at hand. Front seals will be replaced.
