ok, i passed the compression test... now what
whats a reason allot of oil is coming out of my
PCV the numbers were from left to right: 150,
150, 145, 145... the car lost about a quart of oil when i raced 1/2mil @12 psi, and lost 1/8th of a quart when i floored it down a small street after doing a compression test... the car runs fine , smooth, except for the oil coming out of the breathers.


what do these 3rd gens have that would make them

it was only cranked 4 times.... the compression test is weird... basically they remove the spark plugs, and hook up this machiene to where the plugs go, then they cracnk the ignition like 4 time, or whatever times.... my mechanic did it 4...and comrpession builds up, so after 4 cranks it was 150, maybe after 5-6 it would be 200.

on a cool note: allot of unburned gas got in my exhaust during the test, and it bogged big time when the test was done and we started it up again... too bad i didnt have a camera, it scared the **** out of me thou.

even on stock boost oil comes out those things...

to get the right reading it should be turned over at least 8 times, 4 turn overs on a 4 stroks car makes for only one compression stroke.

AND THE EFI FUSE MUST BE PULLED

you dont want fuel going into the engine, dangerous and harmful to many parts.

you must crank the car over until pressure stops building. 220 is perfect, 150 sucks, badly.

your rings are shot. it might also be the valve seals, but rings would have a larger affect on how much oil gets forced out of the engine and into the pcv

go do another compression test to see exactly how bad they are, and this time pull the efi fuse and crank till the pressure doesnt increase anymore.
