I think you are right woody, but it is hard to prove also. I have seen many engine failures in cars and trucks with my years in dealerships, and after taking down engines with damage you cant prove it one way or the other, if the motor has spun a rod brg or main brg,whose to say if it was lack of lube or bad brgs, high rpm, just to many variables. Most engine oil failures on auto engines will happen to the camshaft and lifters as that is where the most pressure is exerted, between the lobe and the foot of the lifter, I remember back in the early eighties, chevy engines in pickups were notorius for wiping off the #6 cylinder intake and exhaust cam lobes, we came to find out that it was caused by the egr valve which allowes hot exhaust gas to come in close contact with the engine parts around the lifter and actually cook the oil away. hence the wear on the cam and lifter. Now all modern engines have roller cams and lifters, so those problems are history.
most engine damage is caused by one thing and one thing only........
LACK OF MAINTANENCE!!!!!!!!!!!!! keep the oil and filter changed and coolant regularly serviced, and all other fluids serviced and you should have many trouble free miles.
