Bernardd Posted December 5, 2005 Share Posted December 5, 2005 how serious does this look? http://album.hybridz.org/showphoto.php?photo=4991&cat=500&page=1 http://album.hybridz.org/showphoto.php?photo=4990&cat=500&page=1 compression on that cylinder was 120, the others were in 129-135 range with a cold engine.

PeterZ Posted December 5, 2005 Share Posted December 5, 2005 Looks like you burned some water, the two pistons are so clean. Can you catch your nail in the groove? Quote Link to comment Share on other sites More sharing options...
Bernardd Posted December 5, 2005 Author Share Posted December 5, 2005 no groove at all, it's just polished a bit. i did blow a headgasket this summer, i may not have noticed it when i replaced the gasket. Quote Link to comment Share on other sites More sharing options...
Cruez Posted December 5, 2005 Share Posted December 5, 2005 Honing might clear it up... or might need a bore job. (worse case) Might want to check the rings in that cylinder. Quote Link to comment Share on other sites More sharing options...
Tony D Posted December 6, 2005 Share Posted December 6, 2005 EEH, it's nothing. Take a look at JeffP's cylinders from when we took the head off last year! And that was still "nothing" it's going back together right now, cylinders not touched. I might take a look to see if the PISTON LAND is damaged causing the marking---but the cylinder wall is fine! My bet is broken land, or ring bit causing the irregular wear pattern. JeffP's was on the opposite side, on the piston thrust face, far wider, and a result of piston clearances at....uh....245+ Degrees Farenheit! If it didn't seize then Jeff, it aint going to! LOL My concern would be with the piston itself as that should not have a wear pattern there! Quote Link to comment Share on other sites More sharing options...

Bernardd Posted December 6, 2005 Author Share Posted December 6, 2005 I'll mic to see if the cylinder is out of round. There is nothing I can feel there, it just looks polished, wouldn't a ringland scratch it more than polish it? The motor ran fine, had no knock, used about a liter of oil per 1000km's which is what it's pretty much alway been since I've owned the car. Hmmmmmmmmmm, I'm seeing a v8 in my future.
