Piston Coatings - Worth the bother?

[TerryS]

This is not something I have ever really bothered with before, but have any of you guys had good results from coating the skirts or tops?

used to run ceramic coatings on differant turbo cars not really sure how much of an advantage it gave but never had one fail

Apparently the skirt coating lets you run tighter bore clearances with the 2618 alloy, which usually rattles around. Cuts down on noise and skirt wear. Crown coatings not many bother with.

Mine are usually coated, skirts and crowns. That said carbon may accumulate on the crown once a few miles have been cloaked up.

I wouldnt worry much about it. Only one I might have an interest in is ceramic coating of the crown.

Even then....my pistons have always worked ok without that too lol

Cheers guys, still undecided. I read an article once (which I now can't find) where the guy took a blow torch to the crown of a coated & uncoated piston. Not very scientific but from memory the coated one lasted significantly longer. This was what had me thinking.

If the piston is going to melt, its going to melt. Thats a tuning issue though, not a piston problem.

A coating may help a little...but I suspect not enough to mkake it worth worrying about
