[HTi]Johnson Posted February 7, 2006 Share Posted February 7, 2006 Hey all. My wagon (1987 Gl-10 Turbo), is being stupid. I pulled each plug wire, one at a time, while it was running...(and this time I didn't get shocked!) The only wire that didn't affect the idle was the thrid cylinder wire. So I let it cool down and checked the plug...it was on the black-ish side, compared to the other 3. Then I did a compression check on it...there is only 45PSI on the #3 cylinder...and the rest of the cylinders are 110-120... I am not blowing smoke or steam out the exhaust and there is no oil in the water or vice-versa. But I do lose coolant. What could the problem be?? Is it because of the turbo being sooo close to the 3rd cylinder? Thanks, Justin. Link to comment Share on other sites More sharing options...
Dylan86GL10 Posted February 7, 2006 Share Posted February 7, 2006 I have the same thing going on in my cylinder 1. But I have a bout 160psi on that cylinder so I'm leaning towards the injector. With your compession so low in #3, you may have a leaking headgastket, a bad valve, or bad rings. Do you have much blow by? Is there bubbles in the coolant? Is the oil milky? If you squirt some oil in cyl #3 and retest, does the compression go up? Link to comment Share on other sites More sharing options...
[HTi]Johnson Posted February 7, 2006 Author Share Posted February 7, 2006 No bubbles in coolant and no water in the oil. About the oil in cylinder...I forgot to try that. Link to comment Share on other sites More sharing options...
