Salutations: > > Ah, the ol' oil-fouling, rotor-dripping, wire-shorting thing. Good > find. > Thank you for the praise I think.. And, well, that was the damnable part of the whole affair - it's not dripping at all - it's a very, very fine trace of engine oil and when stopped and cooled - it's not there at all.. It's just grimy like the rest of the bay on a 300,000k regularly rust proofed car.. The reason my man at Tom's worked it out is - I took it for a hard run around the neighborhood and pulled into the bay immediately. He popped the hood and noticed a fine film on the lower rotor.. In fact - the only reason he was willing to proceed along these lines at all is that when we pulled wire from he rotor it looked shiny in there.. I've (an no doubt the two previous owners who gave up on this) had the wires off repeatedly and the wire cap and rotor are dry when cooled down.. Replacing the rotor and the wires fixed the problem temporarily for all of us - but it would appear again within a couple of hours of driving.. Interestingly - I last replaced my normal black rotor with an orange one last time and this fluke aided greatly in the diagnoses.. > > > On a simply roll over compression test - I'm reading 130-130-145-128 on the > > pistons (304,000k on the engine)..

We turned it on the starter and I have it wrong - it was 130 130 135 128.. The question is, what would be normal compression on the turbo 9000 CD from the factory? Sorry to be stunned, but someone must have the figures here.. > > More likely just the O-rings in the distributor assembly at that mileage. > I don't know if it's worth chasing too much into the crankcase ventilation... Thanks - this is exciting news - the distributor head looks expensive if I have to replace the whole unit.. An O Ring is not always the case as you will know.. Also - having repalced the O rings - is there a rotor and wire cap set I can get that seals a little tighter (like with a lip) on the rotor stems? It gets AWFULLY wet in the engine bay around here in the spring and fall > > Pretty sure, yup. Much appreciated advise, again thanks.. > > Dave Hinz Anyway - now smiling from ear to ear every time I look out at my now (soon to be permanently) sputter free darling in the parking slip..
