Can anyone explain it? In English so that I can understand.
Back this season I had an engine that was smoking like a 2stroke. I bought a crashed one from some dude in Concord NH and did the motor swap. Now I have the old motor to put back into the crashed one.
I was talking to a guy that said that an engine can show no signs of compression loss and pass a leakdown test but still have a collapsed oil ring which would cause oil burning because the oil ring isn't scraping the oil off the cylinder causing it to be burnt off in the combustion chamber. He also stated that on downshifts with a closed throttle that the crankcase pressure is great enought to cause even more oil to get into the combustion chamber causing wicked smoke on deceleration.
I understand the theory but can anyone quantify it?
