Excessive blue smoke blowing out from the crankcase vent tube, which smells stronly of burnt oil and blue in color, and the engine idling very roughly is a strong indication of what catastrophic engine problem? Thanks for the help guys.
Sounds like a cracked piston. Sorry to hear about your problems
X2 , hope your compression test shows different .
x3. Damn LBZ's........
Got the codes.
P0299
P0401
Any more ideas? One injector is knocking pretty hard, and I noticed very low oil level too.
Thanks again.
Also, not sure if you posted or I missed it but what were the conditions before the problems started happening?
Sounds like my truck. Just out of curiosity, have you done any towing with the truck recently?
I realize that, but had you done any extended towing with it a day or two before this happened?
edit: I think the 299 is an underboost code and the 401 code is an EGR code. You need to check balance rates to find out what cylinder is causing the problem since you don't seem to be throwing a misfire code. FWIW, just because you aren't throwing a misfire code doesn't mean you don't have a problem. I never threw a misfire code when I killed a piston either.
Ok, I was just curious about the towing stuff.
To check balance rates you need to open your scantool on your laptop, connect all your cables to the truck and computer, connect the scantool (little green button at the top left of the screen), open the PIDs tab, clear all your existing PIDs, find all the balancing fuel flow rate PIDs (there will be 8 of them) and double click them, now that they are all selected, click the red record button at the bottom, and click the Data tab. All your balance rate info will be displayed there.
