i was racing up Mt Stuart and noticed my oil over flow catch tin was full, i emptied it and after the next run it was full again. be for everyone tells me my motor is shagged and it need to be rebuilt, i just want to know if there is any thing in the rocker cover that could fail (like a one way valve) allowing oil to come out into the catch tin. i am talking about 1/2 lt of oil !!!!!!.
the oil was comming out of the rocker cover breather
i havent lost any power, but the motor was getting hard to start (like a flat battery. but the battery was fine the next morning) probably 2 different problems.
any ideas b 4 i pull the motor out and rebuild it :( ???????

i sounds as clear as mud i know :rolleyes:

What sort oif a catch can setup are you running. Line size, does it run back to the intake etc...
My engine is 270000 k's old and I don't see any oil in my can. I run a sealed can with -12 line to and from it.

How much time do you spend in a parking lot with your performance car? If you do a lot of parking lot driving, and hang out in parking lots, chances are you are a ricer, go home and read import tuner. If you’re complaining about noise you should not be modifying your car. You should also consider no longer being a man, please hand in your genitals at the door.

yes it does run back into the intake, and once the catch can fills up it sends oil through the motor and blows blue smoke (only then does it blow smoke)
it runs from the rocker cover to a catch can, from the top of the catch 2 pipes, one breather (i think) another back into the intake.

So you don't have a pcv valve anymore? Does it pop the dipstick?

if the dipstick is popping out thats not a good sign, the PCV is on the inlet manifold side of the rocker cover pointing back towards the firewall.
If that is not working it wont let the pressure out of the crankcase through the rocker cover, if you have removed it already it will most likely be
a ring issue.

A simple compression test will reveal whether the motor is ok and it's just a pcv problem.
