can anyone tell me a cheap way of testing preasur in crank case?

heres what has been said about problem:
I have recently posted about the oil light comming on and check engine light. i have a 2.2L 91 sunbird. My dad and i have replaced the PVC thing that is connected to the crank case like a week ago and it ran fine then later today when driving the oil light started to come on again, it was going into low idle. so me and dad looked at the carberator and looked at the breather filter and it was really dirty and whe had went and got a new one and it was still going into low idle. (IS THE BRETHER TUBE SUPPOSE TO BE BLOWING AIR OUT OF IT(SHOULDT IT BE SUCKING AIR IN?)?) Anyone know what might be wrong?

sounds like you have some high crankcase pressures that is most likely caused by combustion chamber gasses blowing by compression rings. I'm guessing your car has a few miles, it being a 91 and all. do a compression test, it may only be one cylinder or something. i'd say it's time to overhaul or look for a new ride.

If the air breather was real dirty, the problem I had with a Sunbird and my Firenza is the vacuum hose that goes to the map sensor on the firewall would close when the car was started. The cruise did not work at all. I replaced the hose and it ran perfect and the cruise worked again and I got my gas mileage back.
