I think I may be a case of the old sump Baffle & or no surge protector. 12 trackdays no sump baffle or surge restrictor, on street tyres. Last year EC warm up lap BANG! broken inlet valve #3 right beside where the surge protector shim goes?
On inspection nothing except a metal fatigue caused from surges of hot and cold oil could explain. $4k for a new engine, $1k to repair turbo (Inlet valve squeezed past the Outlet valve made its way out to the turbo), $4k for the labour, $5k on go fast & track longevity bits. Two parts which were included, a sump baffle and a restrictor shim $500.
I think so many thing can go wrong at anytime, there are other related factors such as heat, age of car, KM travelled, how hard a life it has had, its hard to say exactly what goes wrong.
If you don’t have things like a bigger radiator, oil cooler, larger oil pump, baffle, restrictor, I think personally you can limit your risk by keeping the RPM’s below 7000 and not to think you are playing PS2.
My thoughts only!
