My favourite engine builders pistons

I've had these pistons on eBay and they have sold, I've had them in a bucket of petrol to get them clean and get the black burnt shite off them, after I've rubbed them down they are scratched on the top of 3 pistons, long story but they had to change a piston after the first £7500 build so looks like they have scratched them previous to get the shit off, so question is will these be ok to sell on?






The piston that ruined my engine

Not an expert but it the sides not the important bit?

You are right Daz, use some autosol to get the scratches out.

Cheers Jonny

Agreed....."that will buff out"
