Powder on inside of engine

[Dels383TA]

Was just wondering if I should be using a certian kind of powder to do the inside of an engine ie: lifter valley,intake and such parts.Was also wondeing if connecting rods can be coated or not,or will it just peel off due to the oil and fuel in the crankcase? from what I have seen white is the better color to use on the underside of an intake as it reflects heat better.

Internal engine parts (rods etc.) require a special coating. Powder won't do it. I have known of guys painting the lifter valley for better oil return. I can't recommend doing it with powder, cause I don't know.

It takes 350 to 400 for powder to cure, but will scorch at about 275 after curred (so I'm told) I did a guy's intake once, and the powder burned at the area that supplies heat for the choke. Needed to block the port off in the head, but he didn't.

Why would you want to paint the inside of an engine? What would be the benefit? Possibly smoothing of the airways, but connecting rods and rocker boxes? If it came off it would be a disaster because it would fill up the oil filter.

The color of the paint doesn't matter, white or black or anything else, it all looks black to the infra-red (heat) spectrum unless it's a metallic paint. Bare aluminum reflects heat better than paint.

Painting seals the pores of the casting and speeds up oil flow back to the sump. Most engine builders use GLYPTAL It is a non conductive paint that is great for alot of applications. It is usally brushed on and is available from Caswell. Todd
