I was getting on the Interstate, towing my 36 fifth wheel, and as I accelerated to speed, I heard a loud sound, like a massive air dump. Kind of a hiss from a tire letting go quickly but not exploding. After that, I had NO power. My turbo sounds like it is spooling up but dumping any pressure out. I only get 10 psi on the guage, where as before I would get 20, 25psi, no problem. Like I said, it sounds like the turbo is spooling up but the faster it spools, the louder the hissing sound gets. What is my problem? (Well, my trucks problem, I have too many for you guys to figure out.) I can drive the truck but hill climbs are a killer and I start chugging black smoke now under load. I don't know what terms to put in for a search and if I put in "turbo", I get millions of hits. Thanks.

 

I believe you have might a blown cak tube or intercooler,get some soup and water and spray all the tubes and intercooler and watch for bubbles

 

Have you inspected all of the turbo hoses and pipes? You could have a split in one of them or the hoses could have blown off.

 

Welcome to FTE dsbrew I believe the guys are right on the spot, you lost boost pressure from a split boot coming off the turbo.

 

Yes i will also go with bad boots i just got mine had to take out a bank loan but i don't like tow trucks

If you are having a problem keeping the boot on something like this may help

I agree! This just happened to me (in my work's truck, not mine) a couple of weeks ago. I was on the interstate and was having a lack of power/turbo farting between gears. Any time this happens in my truck (the turbo farting), I can solve it by giving it a hard run and blowing it out. I tried this on the work truck, and BAM! Huge boom from under the hood followed by a black cloud behind me. Lots of rushing air sounds and NO power. Come to find out I blew the boot of the CAC tube going to the turbo. Replaced it and all better....power was back with no turbo fart, but the dealer still got us for a blown turbo. I guess what I am saying is that it could be a simple CAC boot loose or blown off, to an extreme of a blown turbo also....

Good luck. The dealer got us for around $2600.....

 

On vacation on tuesday exact same symptoms. Mine sounded like a loud pop and the driver side air leak... I could hear the air rushing but no power. I stopped at a dealer there is a new metal pipe off the cold side of the intercooler. They replaced it $285 (ouch but needed it!) Works perfectly now.

Good luck but I would bet money on a boot or that pipe....

Well, we looked at the CAC while parked and throttling up to 2800 rpm. The silicon hoses appear to be "filling" with air and not leaking. I can't hear my problem without a load on the engine but while driving, it sounds like it is a driver side issue. I am going to look into replacing the boots and any other parts you guys tell me to look at. Does anyone have either part numbers or part descriptions so I sound like less of a moron than I am when I try to order them? I want to try to do this myself to save on the larceny complaint I'd have to file after having my local dealer do it. (trust me, he tried to get me for $700 to change the alternator. The dealer I bought the truck from had to eat that. One year and one week later, with less than 4,000 miles on it, I had to put another one in. $265 for the part and 4 minutes to change it out.)

 

The one that blew does not nessacarly mean the silver one with the 2 blue hoses.

Look at the black one, look at where it connects under the air box basically, you can see if it blew off there with out taking the air filter out.

On my iPhone look at this post I listed the part number. My 06 was plastic and was exact same symptoms as yours. I was out of town and had the dealer put it on. $285. You can get it cheaper I was in a bind though.

 

6c3z 6c640 aa connection -air inlet. $185. This was on my invoice. Good luck

 

Well, I found out what the problem was. Part number 6C3Z-6C646-BA. It is called an air duct on the invoice and it was $183.25. Better than the quoted over the phone price of $224.00. It is the driver side CAC tube (cold side) It was split along the bellows part of the tube and apparently a very common problem. Common enough for my dealer to have the part in stock and know exactly what I needed when I asked. At least it was a stress free repair. I am very happy that it was just the $200 (after tax) part and about 20 minutes of my time for replacement. Still love the Truck. Hope that is the worst of it. Thanks for the help everyone.

 

Did the replace it with a metal one?

 

No, I used the standard, in stock part.

 

Air to Air boot failure is one of the most common problems I have with my class 8 trucks. So much so that every driver has a boot and 2 new clamps in the dog box. I am currently working on finding class 8 boots and clamps for my 6.0.
