if a truck does not smoke when cold or at wide open throttle but does smoke when hot and u first start it up a little cloed of smoke comes out,what could this be? what trips me out is that every morning at start up its cold and willNOT smoke only when its warm and only at start up.it starting to use oil also, i think its valve seals what do all think? any xpierences with this problem?

 

What color is the smoke?

 

looks blueish, white look like oil2 me plus its using oil, i dont believe its the rings cause it would smoke all the time and at wide open throttle and thats not case here

 

It may be a bad valve seal, but I wouldn't completely rule out the rings. If one of the rings didn't get seated properly it can be hit or miss when it will leak and how bad. How many miles are on it?

 

well the 6.2 has 7k on it and the l92s from texas speed have 500 miles on them,i use 10-40 mobil 1 full synthetic

 

can rings make it smoke at warm start up?

 

An unseated ring can do all kinds of funny things, but if the engine has 7k on it and this just started I would lean to thinking it is something leaking with the heads, like the valve seals.

 

well texas speed did the heads and dont know what kind of valve seals they used

 

any body

 

it doesn't say what kind of seals they use on their site just that they are part of the PRC spring kit.

thats what it sounds like to me.
