Are these pistons worth reusing?

Ok i make a sad effor to clean them with gasoline, acid and water adn a bit of WD40 after spraythem with water. Thast why they have some stains and some heads are cleaner i didnt finish cleaning them at all. The last piston was the one that was missing the bearing when i remove the oil pan and its rod moves when still mounted on the crank.

The only real way to answer your question is to measure them. It's simple, they are either within the measurement specs or not. Just looking at them won't give you an accurate evaluation, unless there is any visible and serious damage such as scoring or cracks from metal fatigue.. Measure them..

Hey PEOPLE. Actually I was not being sarcastic about this pistons. I take then to the machine shop and they re- round the button part of the rod, the one that connects to the crank journal. About the piston head I remove all piston pins very hard since they were stuck and take the head for sand blasting clean. Then I lubricated all the pars and re assembly them and again they start dancing and look as sexy as new. Ive been using them for 6 month and no problem.

wouldnt bother wasting money on old pistons, there cheap enough to buy new forged pistons and rods now.

i would just get new pistons and rods.

the pistons are off the motor already so i would just go with new ones

you can always do what Burt Monroe did with his Worlds fastest Indian. he made him own piston molds and when he found the right design he made his own metal combo, i think i was 1 chevy, and 2 of ford. because chevy pistons back in the `30s and `40s had titanium, and ford pistons were Cast, and what you get is a relatively light weight piston that you can handle the torture of running on alcohol at 200+ mph.

@nathanmeitzler Never oil new pistons because of you do not want to saturate the rings, if you do then compression will be compromised. Use ATF not regular oil.

[nathanmeitzler]

Oil them up and if u actually want top notch performance replace ur rings.

unless you are on a budget no piston/conecting rod is worth reuseing in a motor you truely care about

[rcpro17]

Why put them on the cement?? That caused damaged alone!

[loko95ftp]

ill give you 1USD put you have to pay the shiping

[seapeddler]

They would work well as Christmas tree decorations.

You could always tie a rope to them and use them as a boat anchor.

@gt4mazda Holly true. In my country for one piston You will give something like 200pln, it is 70 dollars. In USA i found set of pistons with piston rings for 100dollars. This is sick :D hehe
