Hi Duke,

I'm going to try and find out which mechanic at the shop had changed the valve seals (I have the receipts). If that doesn't work out, I'll have my indy check them out and see what he says about the guides.

I've read one of your previous posts regarding fouling, in which you mentioned that the plugs should be okay even at a quart of oil per 300 miles. I usually drive around 500 miles/month, so I haven't really driven the car around enough to figure out its oil consumption just yet. So far, the oil level has been relatively stable even with the head gasket leaking near cylinder #6, and the slight leakage at the oil level sender.

I've checked the resistance on the wires and they seem to be in spec (all around the same values, based on length of wires). But I will try swapping wires from the old set that I have to see if that is the problem.

Some additional info:
There is no smoke when I start the car, and very little of it on idle while warming up even with the old fouled plug installed. The amount is so little that I can only see it within inches of the tailpipe, so I can't really tell what color it is. Once the engine and exhaust are up to temperature, the smoke goes away but I still smell fuel. There is no smoke on acceleration, but I can't smell the exhaust then
