Blue smoke, low oil pressure, turbo number 3!!! What am I doing wrong?????
 
To start off, this is my wifes truck, 24v cummins with edge EZ tuner. Nothing too special other than its hers. We went mudding a couple of months ago, long story short we got it stuck and water/mud got into the turbo and oil system. We replaced the turbo changed the oil/filter thinking we were good, the turbo lasted a month and started blowing blue smoke. It got really bad so I pulled it and found that it had blown the seals and thrown oil back into the exaust manifold and had been pooling in the #6 cyl. Cleaned it flushed it made sure the oil system was clean and put a new turbo on started truck, realised that oil pressure guage was not working. Replaced sending unit, now to my problem, blows blue smoke on start up until engine is completely warmed up. Once it is warm the oil presure drops to zero at idle. I put 2 mechanical guages in one at the filter and one at the sending unit. Filter reads 15 and sending unit hole reads 8-10. Idle and when we release the throtle is the only time the stock guage reads zero. When it does that the mechanical guage on the filter side is still reading 15- 20. I need some help getting ready to drive this truck across the country and I am wondering if I am gonna blow another turbo. Were could this blue smoke be coming from??? any suggestions would be helpfull!

Would someone please give me an idea my brain is fried. Does this truck have a filter bypass in the oil sysem?

Have you check it for any codes? key trick or scanner?

wam9797 08-16-2012 08:04 PM

PCU code is p 1693 and ECU code is P 0522 (which is my oil pressure code) nothing else when I hook up the scanner

You had mud/water in your oil? like how much? could have done some serious damage internally, the fact that it blows blue smoke until it's warm tells me oil is getting by somewhere and burning until things heat up and expand...

No more than 1/2 a gallon of mud/ water in to oil. We flushed and flushed the motor doesn't seem like there was too much damage other than the turbo....

:argh: anyone know about a bypass valve near the oil filter??

Uh thought that was on the filters?? could be wrong, how high did you get in the mud you mustve pulled it thru the breather?

yep found a hole in the breather where it comes out of the cover water was just below the fan but fan was splashing water in to hole. Its about the size of a nickle... here is a pic...

I'd say 1/2 gallon of mud/water in the oil is a lot :scare2:

ME TOO! thats two quarts, so if you had 10 quarts of oil plus two quarts of mud I think its time to tear her down... or do a compression test and see how much they vary water does not lubricate as good as 15-40 oil, I dont know how far you went like that, but before you go mudding next time reroute your breather... car manufacturers never plan for people like us to take are trucks places like that.

If your vehicle is experiencing some kind of problem in operation you should check out its oil containing machinery for great performance.
