Anyone got any idea why or how this has happen on my pistons out my engine. It has happened on 3 out of the 4 pistons. It would seem like a valve has hit the piston but im not sure how its happened.

Surely That's been made like that! Your valves would be seriously f*cked if they managed to make them indents

Thats what i fort it could be. If it had though it would of been a while ago cuz ive had the car 3 years and my mate had it for 7 years before i had it and he has never had the head off.

That's odd!
Surely both valves would hit the piston if the belt snapped, or if someone timed it wrong though?

i timed the engine up before taking the head off and all timed up ok

DEFO valves hit piston...

But, I was thinking if someone got it slightly wrong at a previous belt change, heard that it sounded bad and tapped like a '6, then re-timed it after...would that be the outcome? Does one valve come out further than the other?

That's a belt snap caused that... Ive ran an XUD 3 teeth out and its fine...

frosty maybe you need to check the rods too!
@tom go read up on your 4 stroke cycle, both valves are only open for a very short time one or the other valve is open for a far longer duration

So it looks like I will get some new pistons depending on price.
What would people recommend? Is there any uprated 1s?

Probably smashed the cam in two shortly after that happened!! Then of course the other definitely wouldnt have!!
 (14-05-2013, 03:43 PM)Ruan Wrote: Probably smashed the cam in two shortly after that happened!! Then of course the other definitely wouldnt have!!like one i bought with a f*cked engine, best snapped smashed the piston and cracked it with an indent like that and snapped the cam in 2
