I was trying to push out a piston on my Ls block and accidentally chipped this corner.


would this be ok to run still? I couldn't get a picture today but the piece that broke is small and broke cleanly.

 

i would think it would be ok but would file it to make sure its not going to score your cylinder wall

does this seem right to any one else?

Yeah I was going to work it down if needed whenever i got it out.

BTW: Any suggestions on getting these things out? lol

I'm afraid I'd have to disagree...

however small it may be, it means you now have one of your 4 pistons that weighs less, which means you will throw off the balance of the engine, which can screw up things in a big way.

and a single used LS piston is probably only a few bucks anyways

*Performance shops when they buy their pistons weigh them each to make sure they are all within a certain weight of one another, if they are not, they have to get a new ones made.

awww [freak] would a small chip throw it off that much?

 

yes, thats why shoppes balance them. You need a new one.

Honestly, I don't know how much it would throw it off, but I DO know that weight differences in pistons has an adverse effect on engines, so I'd play the 'better safe than sorry' game. If you already have it mostly apart you will be spending a fair amount on new gaskets anyways, you might as well drop the money on a single used piston, or just buy a full new or used set to not have to worry about the 'new' piston still being a different weight do to more/less use, etc...

Rule of thumb "when engine internals break, replace the whole thing"

Pretty much the best advice you'll get. When it comes to engine internals, why not spend the few extra bucks to get a new part and not have to worry about the consequences of the originial problem? Do it right the first time so you wont have to tear it apart again. That would just be a pain...

doing it right the first time with engine internals is so important...

I got an ebay headgasket once, and blew it an hour after installing it, which cost me another 3 hours to tear it all apart again, and I spent the same on the OEM gasket anyways.....

 

Maybe I just don't see it. Where's the chip? Did you just nick the piston skirt or did you chop off an entire piece?

 

Dont always listen to what you hear all factory pistons have a weight difference in tolerance all you have to do is take it to a machine shop and have them check it by weight to make sure if its within tolerance also this can be found in the honda chiltons manual if not they can take some material off the other pistons or add some back to that one its called balance and blueprinting it is on the skirt so it shouldn't be a problem but check it better safe than sorry This dasfinc guy is a retard and should be giving anyone advice because he has no idea what hes talking about but if you do decide to run with it i would file the edge so it wont scrap, scratch, or score the cylinder wall.

I'll get a picture of it today if i can

 

Agreed. Do it right the first time.

 

yeah bro this is definitely not an intake or exhaust job.... this is a job that once everythings put back together, its a huge P.I.T.A. to have to redo all over again... id definitely say get the **** fixed first before u throw it in there... even if it doesnt matter an wont mess ur motor up that bad, id still replace it that way ur not ridin around town constantly hittin pause on ur cd player because u think u hear a new noise lol "am i the only one who does this"...

 

It's not worth the risk. At the very least get all four pistons balanced if you want to re-use it.

LOL I can pretty much almost never finish one entire track without pausing it and giving my car the face and listening in. Good luck dude!

Machine shops = $

a new set of used pistons = cheap/free....
