I just read a pretty interesting article in the new Hot Rod mag that had to do with coatings for engine internals (pistons, cyl. heads...) from a place out in CA:
http://www.techlinecoatings.com/articles/a...ation_guide.htm They (Hot Rod) performed a test on a coated vs uncoated piston with acetylene torch, and the coated piston lasted three times longer than the uncoated piston (32 sec. vs 97 sec.) before melting a hole through it. They also recommended coating the inside of the cylinder head (particularly aluminum heads) and the face of the valves. All of these coatings can be applied at home, and cured in the oven (send the wife shopping...unless she's VERY understanding of your cause (IMG:style_emoticons/default/wink.gif) ) Any comments? |

This is what the coatings look like. I had the following done:
Piston Top, Combustion Chambers, Valve Faces, and Exhaust Stub Tubes coated in a Thermal Barrier. Piston Skirts coated in an anti-friction coating. Valve Springs coated with a dry-film that absorbes oil.
