The engine had 30 minutes of running in on a rolling road, 2 hours of set-up and 15 laps of Snetterton on a track day when it spun number one bearing.
Then New crank, new conrod, new oil pump, new oil cooler and rebalanced.
2nd time, it had done 4 laps of Combe very gently, 3 hours of re-setting up on a rolling road (don't ask!), and then 16 laps of Brands Hatch indy.
Nearly everyone says it is an oil feed problem. The only two common denominators was that immediately prior to the failures is that I spun the car. Both relatively low speed (about 40 mph) and on both occasions I remember dropping the clutch as soon as the spin was un-recoverable but by the time I had come to a rest, the engine had stalled anyway!
Thanks for the advice everyone. Anymore thoughts are welcome.
