After boosting a few nights ago, my car has a total lack of power. I did a compresion test: 160, 175, 170, 165 are the results... slight blow by in the crank case, and also the 160 cylinder #1 spark plug was wet with oil. It almost feels like ignition break up when i am driving it. I guess it could be a piston or ringland... anyone have any ideas?

did you retard your timing at all.....or do you have stock fuel system???

Where is the oil on the spark plug? On the engine side or spark plug wire side? If it's on the wire side, it's the valve cover spark plug seals leaking and causing a misfire.

do you have a dump tube?

my timing is at 13 deg right now and gets adjusted through the AEM ems. my timing should be at 16 deg though... I don't know what happened but the plug is wet from the spark side, not the wire side.

leak down test? does it sound like a wrx? when u give it gas it breaks up? my last motor did that and i....crack rings, melted ringlands, and spun a bearing ...who said LS's cant handle 28psi on a t04e lol

PrettyLude

mines did that too, when the ringlands gave, i had alot of oil on the bottom side of the plugs

boostedsol

yeah it breaks up bad when i give it gas... and there is no power. Must be the rings then. damn this sucks

How bad does the break up feel? Anyone know how to test for broken ringlands?

boostedsol

the thing that kinda gets me is that there is no smoke pouring out the crank case breather.... on my last motor when the rings went, it was like a choo choo train of smoke out the crank case breather and oil cap.

turbo could be seized or something could be slowing it down?
