Quote: Borrow a gauge and put the hose on the dip stick tube and run the car with the same set up you normally run an see what the gauge says..... if you have pressure it isnt evacuating even with the PCV and breathers which would indicate a ring issue.... if you dont have pressure its more likely to be a intake issue... a leak check or compression check can not tell you anything OUTSIDE of the cylinders(cant tell you if the intake is sealed or not) Also for a quick check.... change the PCV and make sure its a V-8 one... there is one for a 4 banger also
That is good to know about the PCV. Will the 4 banger part even fit? What is different if it will?
