spin a baring

no



he spun a bearing because he revved the piss out of it or ran her low on oil (or more than likely both)


it's like saying a short throw shifter caused my fuel pump to fail
 
Well, I've heard of a person who installed Mac headers without deburing them first ended up drawing a chunk of metal back in to the combustion chamber.. which I suppose could indirectly result in a spun bearing somehow. :shrug:

Yeah I too have heard this... sometimes if you don't deburr the headers you can end up with oiling problems, not sure how exactly it happens. My only guess is the metal pieces hinder flow from the oil pump, don't quote me on that though. If you are not aware of this problem, and you're consistently in the high rpm range, then you definitely will spin a bearing. The way to prevent this if you buy MAC headers is just to make sure you remove all the slag (if any if present) so it doesn't end up back in your engine.
 
I have heard about the debrit problem too, but never heard of it causing problems with bearing. I'm not sure how it would get into the oiling system without doing damage to other parts first. Usually the problem that occurs is smoking and burning oil from gauged cylinder walls.

thats probably the case, I was just speculating as I have not had first hand experience with the problem. The gouged cyl walls cause excessive oil consumption, which in turn could possibly cause a spun rod bearing depending on how low the level gets and how hard the car is beat.
