Blow-by Question
I have searched with no luck.
What causes blow by? I see people talking about it on here and I can't remember the cause. Any other info on it is appreciated.
Thanks

Blow by is a result of piston ring sealing. Basicly when the piston is on the compression stroke a percentage of the compression bypasses the ring seal and is dicharged into the crankcase. As the rings wear the percentage of blow by increases.
