I recently installed new spark plugs into the 7. Later I went to check them and pulled the rear out normal wear, bit of carbon layer on end. When I pulled the front off clean as a wissle. Anyhow neither plug was weight, and I was puzzled.

I was just wondering how it would be possible. The only thing I could come up with is possible coolant in housing. But wouldn't the plugs be wet? Anyone ever had a similiar experience.

Thanks,

It means you still haven't figured out how to spell to, or is it two?....

No, I know how to spell. Just a late night last night. You know how it is when you post, it looks right when you proof-read it, but then you post it and half the damn thing is mispelled.

Come on guys I meant to say two..

The only thing I can think of is the fronts were 'steamed cleaned' by a coolant o-ring leak. Does your car exhibit any of the nasty behaviors associated with that problem?
Black goo on the overflow dipstick? Rough starting after letting it sit for a few days?

Yes most of the work done by me. The plugs are brand new, and have been used to crank the engine several times, as well as driven with. When I pulled them out only the rear were lightly covered with carbon. The front like brand new when I installed them like they were never used, not possible. I am trying to see if this has any connection with an o-ring failure. I have tried to bleed all of the air out of the cooling system, but it still gurgles out the over flow, and I have smoke out the tail. And it only seems to want to start when I floor the pedal and crank.

Is it possible to drive the car on one rotor?? Because I have been able to easily hit 70 mph on the freeway.

Yes there was black junk in the overflow tank, and also rough start when cold, and also when the block is heated too. Weird how only one rotor can have a problem, and the other be fine.
