White and Blue smoke

LOL now, that there's funny I don't care who ya are. LCG

 

I have a 2004 KW 900 with a twin-turbo cat is blowing blue smoke out of one exhaust and just a little out of the other I'm suspecting the house maybe even a injector what else could it be.

 

My old Detroit does that after idling. Last one did it too. Sometimes it looks real bad like at night under a streetlight . Then almost unnoticeable. I think it has to do with air outside maybe high humidity. Blow by same way sometimes looks like trucks on fire other times just a little. Pittsburg diesel has a video explaining idling and turbo leaking fuel past seal Looks like oil.

 

####. We should have the entire Sistine Chapel rented and lock our own Congress in there until all agree on a bill.

Your funny has me on the floor this morning.

I generally associate white smoke with 10 degrees and lower and blue smoke for cold engine not at temperature yet. (These would be the old iron in excess of 1 million and half the stuff on them don't work... anyway)

 

What's your coolant look like? Dirty like exhaust gasses? Send out an oil sample. If it only happens at idle it probably isn't a cracked a head or cavitation. If it was the hotter the engine gets the more it would expand and smoke. That's my take on it.

Have you ever over heated before?

 

I hope it's not a cracked head. I had a lawn tractor do that to me and it did the exact thing at temperature. It was a little 25 horse Kohler that gave me 10 years bush hog service where it is not really designed to do. It finally cracked. But you wouldnt know it until it got hot enough working and then expanded. Once it did it turned into a old 70's 5 horse briggs. All tired and no go.

 

After its warm and you shut it off for 10 min does it let out a big cloud when you start up again? More so than a cold start?

 

It can be fixed for $22,377.49

 

That's stiff.

Im fixing to drop a new oxygen sensor and one fouled plug to solve a open loop problem in my tahoe (Runs over rich because computer does not have valid input from O2 sensor) It's only 150. Prior to that we were thinking there might be compression or valve issues.

 

Trucks these days are so sensortive..
