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.

always use oil..how thick? i would at least use 30w..

ps if your worried about ring break in then you shold of had the final hone plateau honed so they break in on start up !!..

I use STP motor treatment. I know it will stay on the walls till fire up.

Do your rings ever seat bro ? I put that chit in a motorcycle when I was a kid and slicked up the wet clutches , major slippage !

They seat just fine, I have never had one with blowby issues. I also run the snot out of them as soon as I can, and change the oil extremely frequently. Might not be the prescribed method by the experts, but it has never failed me.

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 .

I use transmission fluid in the walls and rings. Talked to my machinist about it and that's what he's used for years. Burns off easy enough and let's the rings seat, but still lubes skirts for start up.
