Re: HPOP going bad?
Is the CEL
illuminated? Oil level good? Is it oil residue or a puddle? The HPOPs are fairly stout. You can try disconnecting each valvecover harness connection while its running and see what the change is. No change, the two cylinders associated with that connection have a problem. If it changes they should be OK electrically. At any rate, inspect the valvecover gasket pins and harness connector pins for evidence of melting or burning. Cheers!
