760 Excessive Crankcase Pressure 700 1989

posted by  someone claiming to be TexasSteve58 on  Thu Mar 15 06:18 CST 2012 [RELATED]

760 Turbo wagon. 200 K..........Did pressure test on cylinders. 1&2 were good at 110 & 115. 3 & 4 were weak at a hair over 90 on both.Plugs looked good. No fouling. Replaced wires and still has a "idle" miss. Runs good at highway speed. Blows dipstick & lots of oil everywhere ove 5000 rpms. Way too much crankcase pressure.Mechanic beleives it could still be a faulty head. He said if valves were bent & not opening fully, it would do the same thing.Volvo folks in Ga said excessive heat from turbo is very hard on these engines. Hard for me to beleive a "redblock" not good at 200K.And to think,I wanted a turbo..... Might take car to dallas Α hrs away} & find a real Volvo tech. Good folks here, but Volvos make 'em back up.lol. Opinions & advice wanted & appreciated. Flametrap replaced 01/11,including hose & nipples.
