Motor rebuilding

[Chr1s]

Don't listen to the advice from Chr1s above your post. Not any good advice in that post. The first clue is anyone recommending "Polishing pistons?????" doesn't know much about engine building.

HAHAHAHAH, also, and because he CAN afford a full rebuild with new pistons/rings. He clearly mentions money will be an issue (when isn't it) and using the same pistons is fine for a sealing job for a rebuild (what he is trying to do) AS LONG as their fine, which i also stated. So once you decide to use the same pistons, are you going to whack them in with the carbon deposits that have accumulated on the piston crowns ? oh wait, that's ****ing normal ! all engine builders do that !!!!!!

The point of polishing them is to remove the carbon deposits which leave the piston with a polished surface which acts AGAINST promoting further carbon build up, it doesn't last forever, but it helps !!!

Don't go saying he doesn't know anything, JUST by going off my "newcomer" status. I've had PLENTY of experiance in engine building.



EDit: just to make you a little weary on rebuilding for new rings, I've seen a motor throw a rod which has been freshly rebuild (like what ur doing, on the budget so avoid blowby and loss of compression, etc) then his oil pump began to fail for short periods at random, 300km later, it threw a bearing (seized up the bottom end and the rod flew out the side)

Back to my point, it's not always about the rings..my old car before i rebuilt it had 320,xxx on it and the leakdown test showed it had plenty of life "ring wise" left in her. I replaced them anyway as I have custom pistons.
