Re: Too Much Crankcase Pressure? 700 1988

Is it blow by or just normal oil/engine vapor? Do the vapors sort of waft out? With enough crank case pressure to push oil past good seals, you should have quite a bit of venting out the tube.

I was at a Volvo shop earlier this year getting some A/C work done. Next to my car was an '86 744T with some leaky seals and a messy valve cover gasket and oil cap. The mechanic pulled the dipstick and the tube looked like a furnace stack! Car had good compression. Ended up being clogged hoses and fittings on the intake and a clogged oil separator.

Note that the PCV system on these cars is not the best. The turbos, particularly, are prone to leaky oil caps and valve covers. I've read many accounts here, at Swedishbricks, and at Turbobricks with folks struggling to better that situation.

Are you doing the job yourself?
