Happy New Year!
I just cleaned up the pistons for my rebuild and found some pitting on one of them after all the carbon was removed.     This piston was at #1 cylinder. Is it unusable? I'm certain they are NPR 96mm pistons from a late-80's rebuild. I already bought new rings! Any opinions would be appreciated. |

If you are spending the money for Len Hoffman’s heads, then spend the money for new pistons and cylinders too. This is not the time to turn ghetto on the rebuild. It would be like spending $2000 on a stereo system for a $1000 car.

QUOTE(914sgofast2 @ Jan 5 2021, 02:19 PM)  If you are spending the money for Len Hoffman’s heads, then spend the money for new pistons and cylinders too. This is not the time to turn ghetto on the rebuild. It would be like spending $2000 on a stereo system for a $1000 car. Easy now! This is called due diligence (IMG:style_emoticons/default/biggrin.gif) It's all part of me getting rid of all the parts that don't stand up to tough scrutiny. So far, none of the parts I've removed are good enough, with the possible exception of cylinders and case bolts. And some cars are simply transportation systems for a good stereo!
