Wiped Cam Lobe Theory - Imput Wanted:

Crank splash absolutely contributes to the amount of lubrication the cam lobes gets, and how much is whatever RPM X the amount of oil 1 RPM throws. :D
Just don't know how much it matters because some of the cam sections are blocked from getting slung oil.

The only thing I know for sure is that I replaced a cam and lifters in the Wife's 72 318 that were fairly new and had a wiped lobe on the number 8 exhaust and it's been fine now for months with the new stuff in it.
So if it was because of a non existent or plugged oil slinger hole you would think it would have done it again.
Maybe?
