Well, I finally got around to changing out the NGK TR6 plugs in the Cobra for new ones gapped at .032 tonight, and as I always do, I did a compression test. I started with cylinder 8 and got 185psi, great! Moved on to #7 and to my dismay a very dismal 60psi, yes I said 60psi.
Complete results:
1) 180 5) 175
2) 170 6) 185
3) 175 7) 60*
4) 170 8) 185
Im planning to to a wet compression test on #7 later in the week to determine if its the rings like I suspect. The car still runs great and I think I'll just drive it like this for a while without getting on it to much, I have no time or cash right now to pull it apart but this sure has got me to thinking on how to aproach the project when the time comes sooner than later.
Last years results:
1) 180 5) 180
2) 175 6) 185
3) 185 7) 150*
4) 165 8) 185
Any thoughts?
