Blow by yes it is , however the cause which is what you require is due to a blockage in the crankcase ventilation system. The Volvo 850 has a reservoir located on the block below the inlet manifold, several pipes come of it and lead to the air intake hose at the throttle housing, usually this system gets blocked and when this happens the crankase is unable to vent through the correct system and therefore appears as pressure/smoke coming from the dipstick tube or the oil filler cap, oil often leaks fron here too when its blocked.
You need top check all pipes for cleanliness and ability to vent ptressure, failing that a kit is available on eBay to completely service the the PCV system. hope this answers your question and opoints you inthe right direction
This is not that uncommon. Some oil is so hot that it will start to smoke. The smoke can escape through this opening to the engine.
Blue smoke is burning oil.Blue smoke is burning oil.
Sump compression
pcv system is clogged up.
wah wah wah
There are several things that can cause your 1990 Volvo 740 to stall while driving. The most common cause is a bad fuel pump.
yes and ignition relay would..
Probably not the smoke, but certainly HEAT would cause problems.
my truck started to smoke from the rear end when I was driving down the high way and now its jerking around WHY or What would be the cause
Do you have your terminology right....The injector relay would be the computer right??? The fuel pump relay could cause that problem!!!! good luck and let me know
look at:Besides a coil plug or wire what would cause a 4 cylinder missfire on a 2002 Volvo s40?
I know the white smoke would be caused by coolant, which would be leaking into the combustion chamber.
