I got some used pistons for a screaming deal and I was wondering if this one is bad? There is some very small dings on one side of the skirt. The pistons are JE915 -29cc. Let me know what you guys think.

 

I think it will be okay.

 

Does anyone else have any input? Just curious.

 

I wouldn't think as far down as it is. But with a turbo its hard to say...

 

looks like a porous casting, what type of pistons are they? I would use it without thinking twice and I'm fussy.

 

Has the pistons been recoated or is that a casting flaw. Hope that's not spray paint

 

I would send that pic to the manufacturer and complain about the flaw. You might get a replacement for free, and if not, at least it will be well documented if that cylinder takes your engine out.

 

Oh they're used.... Then why are there no marks in the skirt? Weird...

 

Like I said, I hope that's not flat black spray paint, If it is and you install them they will seize up in the block. I would take me a rage with a little paint thinner and see if it comes off.The mark on the skirt, looks like a gall mark, piston trying to seize to the cylinder because of lack of oiling.

 

Mic the skirt and see if its with in the manufacturer specs

 

Looks good to me. As far as for boosting I dont think it could be safe.

 

OG geez I just realized these are used pistons..

TOSS UM IN THE GARBAGE!!!!!!!!! Someone spray painted those!

 

I would send them back to JE and have them inspected and recoated if that is in fact, spray paint. When you rub your finger over it, do you feel any roughness protruding up from the area?
