Mine wasn't changed at 60K kms for preventative maintenance, it was changed at 60K kms because it was actually exhibiting problems. 200K kms is much more usual a time for these things to actually grenade. People generally start inspecting them for problems at about 100K kms.

I'm surprised there was no evidence of bent valves... hardly seems possible, really.

Anyway, back to your immediate problem -- Chad has just been through a "no start" issue with a 968 -> S2 swap, it was a wiring issue, some pin in a harness needed 12V.

Ah yes, here it is:

Maybe check out the "It's alive!!!" thread.

I've never heard of 60K being their usueable life. Anyway my '68 motor has new cams (one piece with sprockets) new chain etc. It just won't start.
The sprockets of the cam shaft were severely worn by 120,000 km on my S2. PO found out when the car was serviced and teeth were found in the sump oil. I think the moral is change the chain every 60-80,000 km, or the cam sprockets will wear out. The PO was then up for the Cams (around AU$950 each!), chain and tensioner at the same time.

Guys thanks a heap for all the info and suggestions. You guessed it she runs and is (I'm told) a ripper. Special thanks to Lemming who provided the wiring change instructions posted by Todd H. I suppose I should thank Todd H as well. The story; in case anyone else has the same trouble. Until we got the Todd H authored wiring change instructions my tech wondered why there was a spare wire on the '68 engine harness.It normally plugs into the '68 alarm which my car does not have. Apparently it draws its 12v+ from the alarm. Well my tech wired it into ignition and viola- she fired up.Special thanks as well to Joe Cogbill in Georgia for his patient support. You could not do business with a better bloke.
