Re: More thoughts on excessive crankcase pressure 200 87

posted by  someone claiming to be Peter Hertzing on  Mon Nov 27 03:00 CST 2000 [RELATED]

I've always found that the true messure of crankcass pressure was if the oil dipstick was "blown out of its tube." If it is not, I would replsce the filler cap gasket. The only other really wierd one I have run into was high crankcase pressure caused by a plugged exaust, This will not show up on a compression test from me experience but was the problem on my 88 740. Check to see if a smaller aftermarket muffler has been installed. The Volvo tend to use a large exaust, with at 2 - 2 1/2 inch OD

Good Luck
