jagardh;49591 wrote@phonsa i did change the PCV (volvo OEM). Do you mean that this can still be the problem and that it might be fixed to change one of the original hoses?
Yeah that's right, one way of checking if the PCV is still choked is to get a disposable plastic glove + rubber band and secure it around the engine oil filler neck. Then start the car up and let it run, if the rubber gloves inflates then you still have postive crankcase pressure.
Another indicator is smoking dipstick when engine is running.
This is the 5'8" PCV hose mod i was talking about.
