Hey guys just pulled them today from my friends 4AGZE, compression was 160 - 158 - 160 - 156 across the board. Looks like he had some detonation.
But do you guys think t would be safe to run these again??

 

pics dont work

 

one pic works, the edges look kinda chewed up. How do the sides/skirts look?

 

the skirts themselves are just fine no damage there. just little pits on top of the pistons.
ring lands are good too not cracked anywhere. Do you think that the little damage on top
of the piston would cause any real problems The motor is 8 : 1 on compression with these
pistons BTW.

 

I think you should sell them to me Too bad it wasn't the newer version, with those nifty 8.9:1 compression pistons. Them ***** are forged. I think you should go to a machine shop and have them clean them up and assess the damage.

 

honestly, if the lands and skirts are good, and they are cheap, Id try them myself.
