How do you know if your turbo is blown? My truck sounds like its leaking air in intake. Sounds like air hose when WOT. When I brought it to the dealer he said it is blown. If it is why would it sound like this? I thought the intake was leaking somewhere but they said no. If it is blown what Turbo to you guys reccommend, stock or after market. I do have a TST plate (240/605) and a full DTT trans also. Will be putting it in myself.

Thanks in advance,

Rob

 

Take off the turbo intake hose and look inside. If it is blown you should see some serious damage or at least metal flakes. Pull the compressor wheel in and out and up and down, you should have little play in the shaft.
Sounds like you do have an air leak. Inspect and tighten all turbo hardware such as hoses, clamps, manifold, intercooler, ect. Start the truck and spray soapy water along the clamps ,turbo hoses, intercooler, etc. Then, rev the motor up to around 1500rpms and look for leaks. May not see anything, but could see something leaking before you spend all day looking for a big leak.

Fill out you signature, helps to diagnose problems

 

I've seen quite a few lower intercooler inlet boots with a cut in them caused by hitting part of the sharp fender when expanded from high boost. When there is no boost you can't see the cut nor even see how it would hit the sharp edge.

If it sounds like an air hose then I would say the turbo is working, but you have a huge leak somewhere. If the turbo was blown, you wouldn't be able to get out of the driveway for the smoke and lowwww power.

The above recommendations are excellent and should have been done at the dealer

Thanks Again

I looked at turbo today and it is shoot. Truck has no power and alot of black smoke coming out. Should I put a rebuild one on or aftermarket turbo and which brand? I am looking for reliability and one that not gonna go deep in my pockets.

Thanks
Rob

 

If your turbo is shot go to www.piersdiesel.com/ContactUs.htm. You can call Piers and get his recommendations. He won't steer you wrong. I got my turbo for about $700 from him.

A diesel mechanic that works on the generators at dads work, says that if you have a blown turbo, and the oil from it gets in the intercooler, that when you put a new turbo on, the new turbo will force the oil from the intercooler into the manifold, and cause the truck to rev as high as it will go, because it will run off of the oil, and even if you turn the truck off, it will continue to run. He said the only way you can stop it is to pull the air filter hose off the turbo, and put a clipboard or something flat over it, to keep the turbo from sucking air, and wait till the motor dies. Not sure if this is true, but it sounds very reasonable to me. He said you should clean out your intercooler before you start the truck back up.

Rob, what did you find that brought you to your conclusion?
I can understand a turbo going bad, but the sound of the air you were describing still has me wondering.

 

I check all the connections nothing leaked. Then the other day while plowing my truck just lost power and nothing but black smoke out of exhaust. Also, it stopped making any air noises like before. Taking it apart on monday to replace. There is a cummins repair shop about 45 min away and may just get replacement there, need a quick fix before it snows again.

Thanks
Rob
