What is the effect of excessive piston blow-by on a)crankcase ventilation?
Answers:
massisve amounts of blue smoke and oil pouring out of the breather vent,ultimately there is a danger that the piston will "suck" oil up from the sump and start burning that.result you WILL NOT be able to stop the engine from revving itself to destruction
16 years in trade seen it on big truck engines scary stuff !
Your real problem will be burning of oil.
It'll empty it of oil and/or blow it all over the place from compression!
i dont know but damn your question got me hot
the affect..or the cause..
the effect will be oil coming out of place it shouldnt.. crankshaft seal, dipstick, rockercover..and others..
It'll pressurize the engine. The PCV valve can't handle that much air flow. You'll start blowing seals and gaskets.
Your dipstick and oil filler cap will eventually blow off. On over-run (coasting with no throttle) oil will be sucked into the cylinders, burnt, and come out of the exhaust as dense blue smoke.
engine worn out , it will burn oil , run sluggish , smells in cab ,(poor starting although not always) plugs oil up and cause missing, poor petrol milage
