94 Volvo 850 Turbo 2.3 with crankcase pressure and oil leak

[rippertele]

I did. Well I stuck my finger in each hole and could feel the interior of the engine. Nothing seemed blocked to me. Why would a car manufacturer place a seal in such an area that requires more cost in replacemnt than the car is worth? I just don't get it.

So where could this block be?! The oil leak from the rear seal has all but stopped when I ran a vacuum line from the dipstick to the vacuum tree! I'm lost! Can anyone help?

I MIGHT HAVE FOUND A FIX ! im gonna try itand see if it helps try eplacing or cleaning the flame trap. check out this info !

the flame trap (a replacement for the old PCV valve in the "positive crankcase ventilation" system) prevents engine backfires from igniting in the crankcase. However, airborne contaminants and oil residue will eventually clog this device and cause excessive crankcase pressure. Symptoms of this problem may include finding your oil dipstick lifted up from its entry tube and worse, leaking engine seals.

HOPE IT HELPS YAH

Any update on this? I got a similar problem on my base 1995 850 non turbo.
I replaced the entire PCV system, a new oil trap, all new hoses and lines, new flame trap, cleaned out all the holes completely but the crankcase still holds a great amount of pressure that it explodes after about 30 seconds of cranking, shooting smoke everywhere and oil everywhere on the engine cover.
