your oil resevoir is to full
breather tube from crankcase or valve cover brings blow-by to the air cleaner to reburn. excessive blow by will be heavy with oil in the air.
The engine is getting worn and blow by is getting into the crankcase and forcing oil from the valve cover into the air breather.
Engine oil coming from breather pipe
The oil might be getting into the air breather of your 2000 S10 pickup if there is a leaky gasket on the engine. It could also indicate the air breather housing is cracked.
oil in intercoolereither turbo seals leaking or excessive blow from engine via tappet cover breather or clogged air filter or under capacity air filter could be some of the causes kulvir66.comIndia
valve guides and oil rings are most likely worn but a pcv valve can be stuck and blow blue smoke
If I understand correctly, you're getting oil in the air filter that's building up around the "vent" hole??? That's PROBABLY the crankcase breather pipe and it's an indication that the engine has a LOT of "blow-by". Blow-by is a condition that is typically caused when an engine is not adequately maintained and exhaust gasses leak past the piston into the crankcase. The exhaust gas MUST go somewhere, so engineers provided a breather tube that keeps the oil vapor from getting in the air. But... when an engine has a LOT of "blow-by", the oil will build up on the inside of the air cleaner and make a mess.
usually a gastet problem Check the breather tube, you might be getting "blow-by" into the intake.
blow back or blow-by is pressure that builds up inside the engine causing oil to be blown out of vent,oil stick,oil filler cap, or into air breather.. Causes of blow-by ---- Bad PVC valve (Positive Crankcase Ventilation ) Worse case is worn piston rings or cylinder walls - engine needs to be rebuilt. http://en.wikipedia.org/wiki/PCV_valve
there is a check valve in the oil system that is stuck open over filling the oil tank will cause the dipstick to blow out of oiltank
remove the air breather on the valve cover add oil there
the valves or rings are allowing compression blow by to enter the crankcase which causes excess pressure that is brought to the carburetor by the breather tube. your engine is getting tired or you have too much oil in the crankcase.
