2.7 Leak Down Test
 

Here's my second question for the morning. I took the valve covers off to upgrade them to turbo style covers and while open, I had a close look at the cams and rockers. Not pretty. They're coming out now and are going in for re-grind. I also did a leak-down test this weekend. This is what I found... #'s 1,2,5 & 6 are less than 5%.

#3 was a weird one in that it measured 35% and could be heard coming out the intake valve only. I looked in with a flashlight and there was debris between the valve and seat. When I cleared the debris and re-checked, it was down to 20%, but now I could hear it coming from the exhaust valve. In turning it over and rechecking several times, the lowest it got was 15%.

#4 was a steady 20% and was coming from the crank case. The engine has 130K on it with a full rebuild done at 94K. The car was neglected and when I got it, the oil was bad. I'm hoping that #4 might be just gummed up rings and that running it might help fix the problem.

What do you think and what would you do at this point.

Thanks...

you can either drive it and hope it clears up, or tear it apart and go through it and know where you stand.

dump some techron or berryman chem-tool or similar in the gas and take it on a "fang" (a hard drive). If things haven't improved after that you may have to start taking things apart. If you search for "carbon build-up techron" or something you'll find more info.

what did the "Full rebuild" consist of?

It has been said many times- throw the leak dwn tester away and do a comp. check and see what it is doing in the real world.
