You didn't have CHP look at it and maybe fix it for free?
Ok I pick up my motor on monday, it had two blown pistons and one scared cylinder wall which L&R Automotive in santa fe springs said it would hone out, they replaced two pistons I got new rings and bearings with a re-balanced rotating assembly for $900.00 he promissed it would be fine now and to have it re-tuned because he said that it didnt seem to be a build issue with the motor, Steve @powertrain dynamics had tuned it so im going to have him look at it, he has too good of a reputation around here so I think im going to let him re-tune it unless there is somebody better that anybody knows about here in southern california... While it has been down I had the headers ceramic coated, PS and ALT brackets powder coated in xtereme chrome along with my C&L inlet tube and changed my hyperblack saleens for chrome saleens, Im hoping to be rolling again in two weeks.
They would not look at it, they said they only had a 90 day warranty and labor alone was going to be over a grand for me, they said one thing one day and when it came down to taking it to them they backed out... but they really aren't to blame, after the tear down it was obvious it leaned out and they wouldn't have fixed for free anyways within the 90 day period and it would have cost me ALOT more to fix. Given the work beign done I think I got a pretty good deal.
that's good news that you are getting back on the road soon
so did detonation cause your problem?
That doesnt look like detonaton to me...I had motor lean out and it made holes in the TOP of the pistons, not tear up the skirts...There was no oiling problem was there? What about junk on the walls/in the oil? The ring lands are not even FUBAR...I think there may h ave been something else going on in there...Did it overheat or get real hot?
Wow man, that sucks. I'm siding with squeeze here, that doesnt look like leaning damage, if the top of your piston was white or melted. that looks like an oiling issue or possibly a tolerance issue (piston too tight or too loose) . Thats really odd damage.
