Initially I thought my problem was a fuel issue - I thought we were getting an intermittent lean condition. The engine would run fine for 2-3 hrs and then just explode. What i finally realized was that the crank angle sensor (distributor) would heat soak to the point of failure and then the ignition timing would become erratic. All i did was to make some heat shielding to protect the CAS from the header heat and the engine has been bulletproof ever since.

So how did you fix it? I have braoken ringlands in the past but on engines with lots of hours on them. I did not find the normal signs of detonation that I would have expected. But these things do turn into a big freaking oil pump whrn they loose them.
