Well I got the pistons Greg sent me and they were filled with carbon deposits and the simple green soak was not working very fast,
SO I took them to the machine shop and had them hot tanked.
NOW after they were done it appears that the iron coating has been removed in certain areas especially around the skirts.
does anyone have any idea if these pistons will gall in the freshly honed bores?
I used a new stone hone with felt pads glued to them and Sunnen AN-30 silicone paste the bores are all dull matte in color.

do you think the carbon could have damaged the iron coating just sitting.
I was soaking two of the pistons up to the ring lands in simple green but it was taking a long time.
The hot tank solution is a soap you can put your hand in without too much worry it rinses off with water

I would send them to Swain's for their PC-9 coating on the skirts. Their coating has titanium disulphide in it and I suspect the reason it has been successful when used in the 944 engines is the fact it has that compound in it. That is a dissimilar metal. They will coat used Pistons as long as they are clean. It is not an expensive option.

Stan,
Crap, sorry to see this, did they say what was in the hot tank? I used the Berryman cleaner in the gallon can, soaked them for a couple of days and then scraped off the carbon with a plastic brush, worked like a charm. That being said the actual reason I was posting is that I'm curious about the drain back holes at the oil rings, did the piston come with those or did you drill them yourself? My pistons didn't have the holes so I had to drill them myself.
