Question On Coated Pistons
Someone has brought it to my attention that when assembling an engine and using a piston with a coating on the skirt there is no need to oil the rings or the skirt . How many of you guys have heard this or use this method . I am told you get your best ring seal this way . Curious . I have always used a light coat of dino oil .

I have assembled several engines using Calico coated pistons. I have always oiled the skirts, pins and rings. I even oil up the cylinder walls. I cant see any reason not to oil them up.

That is how I've always done it . I'm old and times change along with methods and materials . I was told NASCAR engine builders stuff these pistons in dry . Trying to find out if there is any truth to it . An old drag racer from Canada told me this . Yea and then there's the NASCAR engine builder thing again . Curious that's all .
