The volvo is a 97 with 180,000. The problem is there is white smoke coming out of exhaust, The motor has a lot of pressure in it. When car is running and you pull dip stick for oil, you can hear the pressure being realeased. When coming down a hill it really stinks from exhaust fumes. This all just started happening. Otherwise the car runs good. I have been hearing, head gasket, piston,rings , pvc valve and erg something.
Can anyone HELP !!!!!
Thank you
"White smoke" (steam) indicates a leak between the cooling system and the combustion chamber(s). Go to a good mechanic for a cooling system pressure test. I suspect a head gasket. Check your coolant level.
The pressure sound through the dipstick hole *does* sound like a ring problem. Again, a good mechanic can diagnose this.
Also have the mechanic check the PCV valve.

I'm no mechanic but just want to confirm something. I always thought white and blue smoke were oil burning and black smoke was coolant.
I'm thinking he's burning oil. If so, perhaps a SeaFoam treatment as a cheap first attempt to clean, along with PCV maintenance and then start examining hardware.

Oil smoke is light colored enough to be called white if we aren't too critical about it :-) That's what I think is going on - crankcase pressure is building up and forcing oil from the turbo into the exhaust.
