Limp Home and Check engine light

[jd811]

I installed a 5" MBRP turbo back on my 05 about 4 weeks ago, for about 3 weeks now the limp home light has come on about twice a week. I figured this was just becuase i did do a tuner yet. Today on my way home from work my check engine light came on and it was the EGR positions sensor. After reading a couple forums i realize i may have a bigger problem than just a tuner. Maybe a week ago when i started it i blew some decent white smoke and it sounds like that may be coolant in the motor.

I plan on buy ing the SCT Tuner tomorrow but now after seeing i can get it with differnt tunes already installed i would like a point in the right direction wiht that. My truck has 164,xxx on it and id like to keep if for a while longer. If i should install and EGR delete or aftermarket i will but again i am new to the modifications of a diesel.

Any advice is greatly appriciated and i understand there are plenty of forums out there to answer my questions but i have mulitple issues (always something) and im afraid i dont have the time, i drive roughly 200 miles a day and it will probably catch up to my truck quick if i dont fix it. Thanks again

What is the condition of your coolant? What is the coolant level?

If you're getting the limp home mode and white smoke out the tailpipe the last thing you want to do is add a tune to your motor now. Check your coolant in the degas bottle. Is there oil in there? Check it with the engine cold before you start it in the morning, this is the best time as it allows the oil to come to the surface of the coolant better.

If so, you may be in store for some head gaskets.

Sounds very much like a leaking EGR cooer (losing coolant AND white smoke). To confirm, you can park on a downslope and pull the EGR valve (look for coolant in the intake). An EGR delete will take care of it except the oil cooler is probably plugged at the coolant passageways also. You should replace or rebuild the oil cooler.

Thanks for the advice, ill take a look at my coolant this afternoon before my ride home from work. Sounds like my best bet is to do an EGR delete and a new oil cooler. Thanks again
