Mystery "Valve" noise puzzle solved
After discovering that the noise wasn't a lifter and wasn't a rod knock, I disassembled the front of the engine to discover that my problem was a loose cam sprocket bolt. I don't know if it was torqued correctly by the PO (I suspect that it was) or if it needed some loctite (which it will get when I assemble it again).
Luckily I just bought a used cam, housing and lifters on Ebay, so total repairs will not be too expensive. I will install the used cam and pulley, since the one in the engine now has a bad keyway. I will also replace the seal, bolt and key.
The head was just installed so everything else is hopefully OK.
I am new to the 951 so any suggestions on what else to check will be welcome. Tha belt has only 2k miles and a few months on it so I will probably re-install it.
