White Smoke w/ loss of power - Now with Updates!

[nlcougar]

This was posted in the Problems forum but am looking for a quick answer. I appreciate the help!

Got a quick update and a few questions for you guys.

I took my 08 into the dealer on Wednesday with a couple of problems which are down in a thread below:

smoke from front passenger fenderwell??

Talked to the diesel tech just now. Turns out I had a leaking exhaust which caused me to lose back pressure and was causing the whoosh noise on decelerating.

Also had a bum oil cooler. Was not cooling oil therefore the truck was running hot which was also causing the loss of power.

So now the cab is coming off and a new exhaust and oil cooler are going in.

A few questions for you guys:
Dealer recommended a coolant flush, oil change and injector clean/flush. Are these necessary? Will the coolant flushing cause problems with the existing EGR cooler? I'm guessing they would do the flush with the old oil cooler first before installing new. I want to do a flush and put in the EC-1 coolant as recommended and at some point in the near future do the EGR delete but what process should I take? coolant first then EGR cooler?

Any help would be appreciated? Thanks.

I am having my cab pulled for bad oil cooler now as well. I am going to also have head gaskets and egr cooler replaced while it is off. Better now than later and repull the cab. deabating on studs.

Why are they pulling the cab for an oil cooler??? No need for that at all. The oil cooler is directly under the oil filter housing in the front part of the engine V.

Good question. But im thinking it had something to do with the exhaust leaking. It was causing my turbo to wheeze and lose back pressure. I'll ask when I talk to them tomorrow. I always thought the cab came off for something like that.

In my case I was told to change the egr coolers it needed pulled, I also want head gasket changed.

If they told you the cab needed to come off for EGR cooler replacement , then they blantently lied to you. I removed both EGR coolers, the EGR valve/ elbow, all the hoses/ brackets assocaited with the coolers and plugged the coolant ports in my driveway, without cutting or damaging anything (in case one day I ever needed to put them back on), in about two hours with regular hand tools. It takes more time than that to remove / reinstall the cab. Now for head gaskets, it would be easier to remove the cab (they can be done cab on, but I wouldn't want to do it).

It didnt matter in the end It needs a motor.

Why did it need a motor?

oil cooler exploded which allowed the coolant and oil to mix most of the oil was pumped out via the coolant degas bottle and all over the side of the truck

If your oil cooler is bad now more then likely the egr cooler needs to be replaced with a bullet proof one or just delete the egr cooler which is what I would do.
