Q.
Because it's total B-S, the valve stem seals just deflect oil, a slight over fill has ZERO to do with failure...
I've checked hot and cold for my 45+ years of vehicle ownership, as long as the oil is given three or four minutes to drain back to the pan the level will be within a small fraction of cold reading... Remember oil does expand when hot, so theoretically it could read higher than when cold, though I've not seen a major difference in any engine I've ever checked...
