WHAT happened is solved. There is no head on the exhaust valve. Why is a mystery still, but it is what we suspected. The Duratec has been bulletproof until this. It only did 120,000 miles on the road, then 240 laps at Kent, 195 at Sonoma, 260 at Kent again, and for no reason at all, after only 47 laps at Thunderhill, a valve let's go! I should complain to Ford!
