High Crankcase Pressure || Cleaning The PCV System  || My Daily Driven Volvo 945

Having issues with High Crankcase Pressure on my Volvo 945. I have noticed that the dipstick is blown out sometimes du to the high crankcase pressure. Probably, partly due to a clogged up PCV system, and in this video i go and get it cleaned out on this is a B230fk engine.   

I don't expect this to solve my problem, but keeping this clean will certainly help. 

We will do a Leak-Down test in a future video to see if we have compression leaking past the piston rings or maybe have some other type of problem that is causing this abnormally high crankcase pressure. 

I don't recommend using silicone sealer in the place that I use it in the video, but this car has to keep its costs down so i didn't want to replace the entire hose that goes down into the crank housing, but if perfect is what you are looking for, that would be the "right" thing to do.  

If you do use silicone, beware that it will probably be harder to remove the canister the next time around.
