Are these symptoms related?
1) on 30 C days, after about a minute of heavy throttle the engine suddenly starts blowing a huge smoke screen. It goes away instantly on easing off the throttle, and the engine continues running as normal. The temperature gauge remains on 80 C. On cooler days, nothing untoward
2) the oil pressure when the engine is warm is consistently 40 psi, except on closing the throttle on the over-run when it drops to 30 psi. Pressure is 10 psi at idle when hot. Oil is new and is HPR 15 (25W 60 Penrite).
