I've finally find the problem with the car, I've done a compression test, on each cylinder, and the result is : cylinder #1: "0" PSI cylinder#2: "15" PSI
cylinder #3: "30"PSI and finally cylinder #4: 22PSI.. WTF??!!

How could I find if it's the piston rings or the valves? remove the valve cover and check?

Do I have to remove the crossmember to remove the Oil Pan?
Oh and, could I put the head of my old 2.3N/A, or simply the valves on the turbo engine?

thanks

try getting the cam timing right first. There is nothing that I can possibly imagine that would blow all 4 cylinders that badly. Hell, when my rings were broken in #2, it still had 70psi cranking.
Oh yeah, squirt a little oil in the cylinders, and retest. If compression markably improves, then it is the rings, if not, then it is the top end (valve, HG, cam timing, ect)

Done, nothing is changing, no any improvement.

If i turn the crank pulley, it become pretty hard when I am at the TDC point, so I think that the valve is ****ed up....

get your timing all correct like bhuff said...unless your pistons halved themselfs, you would get 50+ psi cranking...heck i cracked the piston skirt, broke both rings AND blew the headgasket and managed to make 50psi

I'm going to bring it to my friend garage, and I'm going to open it, and see what it look like inside, but yesterday, we've remove the valve cover, and all the valves look perfect.. this is why I need to get it out of the car, open it, replace all the piston rings...

Damn, I'm tired.. lol

Did you read any of what we just said?
You will not find anything wrong with the engine internally. The cam timing is way off for some reason, and needs to be reset.

cam timing or somehow a valve got bent. if the valves are not shutting correctly they will look right from the top but will just let all of the compression back out as it gets it.
