Tim, this was just hard road driving but I do corner pretty hard. Even with a full sump of oil I could get the light to flicker on hard cornering if I was shifting. The car can still go round corners faster than it's driver! There has been several events leading upto the death of the crank which make me believe it to have been oil starvation due to surging oil and air pockets.

Mark, do you recon I'd be better with a simple baffle on a big capacity sump rather than a gated affair?

Got to do something as I can't keep throwing a crank and rods in it!
