My truck was running and I unscrewed the oil fill cap and I have some smoke coming out, not a lot but you can see it. Do I have a major problem about to surface or is this normal?

cquestad

how much is some?

At idle I would be scared if the truck is warm.

O.T

I have lots///
A stock engine that is tight should have minimal to nothing for blow by.

If this is on your '07... you got something goin on in there.
Rings, probably... but who knows... anything that provides a path for the exhaust gases to get into the crankcase is suspect on something that new.

GOT BOOST?

Guys, his truck is pretty new, his rings may not have set yet. I would expect some blowby if the rings aren't set. And anyhow any you are gonna see some blowby from these trucks anyhow.

Well it not not alot, but you can see some... and yes the truck was warm and I have 73k on it... I am in sales so I drive alot everyday, is this some thing i can take to the dealer and get under warranty? Of course I will take everything off the truck, what do ya'll think, I am getting close the 100k mark and then no more warranty so if I can get some free work I will try.

cdennyb

if you got 73K on it and it smokes warm... I'm thinkin there's more there than seating the rings...

From my sig. do you think any of that had a hand in this, i am a little nervous to say the least... or am I making a big deal over nothing?

johnh

all engines have some blowby, if your'e really worried about it take it to cummins and have them check it.... i'll bet they won't find any problems

cdennyb

yea, I'm in agreement with that last comment 100%. Probably nothin wrong and if you're the only driver, I'm guessing majority of those miles were highway. You know, those taxi cabs in New York last almost forever because they never hardly shut 'em down!
If those engines are always warm and runnin... they live good.

I'd run it and with those kind of miles you're probably going to trade up soon anyway. LoL
I hear those Cummins usually need an inframe overhaul at 300,000. Better save up for next years overhaul! LoL

kw5.9

LOL!!!!!! i hope you guys are right, lots of hwy time and she hardly gets turned off, as far a trading up I love this set up i will be calling cummins for a crate befor she get traded! When I am done with the over haul I should be around the 1000hp area!
thanks for all ya"lls info

They all do it. making big deal over nuttin... I got lots to i have a stedy stream of blow by untill it gets warm and i only got 1100mi and about 40 hooks!!
