“Toyota is currently recalling 100,000 vehicles for engine failure due to metal shavings internal to the motors.”
I don’t doubt that there’s a problem but you’d think the shavings would either settle to the bottom of the oil pan or be caught in the oil filter.
Maybe the problem is that some rubbing surfaces are producing shavings continuously.
I heard it’s possibly a tolerance issue at the crank shaft......engine gets hot and theres not enough space for parts to expand......it would probably only take a few thousandths of an inch to be an issue.
