Haven't raced the car in a little over 3 weeks and the last time I raced it ,the weather was pretty hot and very humid. Went through to pull the plugs tonight and I noticed that number in 3 and number 6 had a little bit of white on the inside and had some Rust specks. Also looked through spark plug holes and I could see a little bit of a rust ring on the exhaust valves of number 6 and number 8 on the top side not on the combustion side. Could this be condensation or could I have a head gasket leak somewhere any thoughts. I will post pictures as soon as I figure out how to.[URL= ]Plugs[/URL]

A leak down test might be in order.

I experience the same issue with running Q16. Its a little more pronounced. It did the same thing running C14 also. No coolant problems either.My problem is the inside temp of the shop. Which is cool most of the time. I have dealt with this for years. Bore scope great little tool. Now when i put the car up for the season, I pull the plugs and spray some WD40 in the holes, spin it over and re plug it up. But like CV stated above, leak down first in order. I have a friend that has the same issue with the Q16 in his home garage. He puts the car back in when the motor is still warm. I will see it around the margin of the exhaust valves also.
