It could be a number of things but must be diagnosed via computer code check. If you are unable to do so yourself, find a reputable Volvo mechanic. It could be the air mass meter, a bad O2 sensor or something related. Mine turned out not to be the air meter but a bad ground wire going to it. Didn't find out until $400.00 later.

The smoke coming from the valve cover and dipstick is called blowby. It is combustion gases the have passes by the piston rings . A small amount of blowby is normal on all engines. The PCV system(Positve Crankcase Ventilation)pulls the gases out and directs them back into the egine to be burnt again. I would first check the PCV system to make sure it is working proper. Also a compression test of the engine will tell you which cylinder is not sealing proper. If the compression test is ok, a leak down check of the cylinders will determine if the engine is wore out.

Sounds like you have a clogged PCV valve thats the valve that lets the gases that get into the crankcase be rerouted back into the intake. It's silver about two inches and is usually in a rubber fitting in the valve cover and will have a hose on the other end. it's no tools installation just pull the hose off pull it out and replace with a new one. thats the first thing i'd do - 10 mins and 10 bucks should do it

Its the problem of oil.The oil is getting burned out. The vehicle is either burning oil or it is moisture in the gas chamber if you notice white smoke from the exhaust. This is a common possibility.but in some cases this white smoke is not due to oil burning.In that case
White smoke from the exhaust is a symptom of coolant entering the combustion chamber. Normally this is a sign of a blown head gasket or cracked head. And this is not a common problem must be repaired immediately. You must STOP driving this vehicle or you will cause serious engine damage. you will have to get both this possibilities checked.
Thanks. you can rate this solution and show your appreciation.
