When a race engine goes KABOOM

I remember a quote from a team running a Torana at Bathurst one year - they said the car was retired due to "electrical failure"

Someone asked the driver about that reason, and he laughed and said "well yeah technically, that is correct - the actual cause of the electrical failure was a piston coming out of the side of the motor and knocking the generator off...."
 
What a good deal of damage!
 
Hi.

Interesting. The interviewee "Ken" was mentioning that the fine metal particles from the excessively worn thrust bearing/crank were progressively blocking the oil filter, to which he attributed the diminished/loss of oil supply to the bearings and their subsequent failure.

Do engines in racing vehicles not have an oil filter bypass valve, for occasions when not enough oil volume is flowing through the oil filter?

Of do they just rely on the Pressure Relief Valve to dump excess oil flow downstream of the pump back to tank?

Cheers.
