How much start up smoke is too much start up smoke?
When the truck's cold, I get a pretty noticeable puff of blue smoke on start up. It lasts longer the colder the air temperature is, but goes away in the first 30-45 seconds of run time.
If this were a gas engine, Id say I have a leaky valve guide/seal. Does that happen on 6.0L engines, too?
On a separate note [or maybe related note, I don't know], what is the condition that causes long crank times on warm engines? I find that when the coolant temperature's north of 180*, it takes longer to start than when the coolant temperatures at or under say, 160 or 155.
