Title: Diesel Issues
Post by: jstone on September 03, 2016, 04:15:21 PM: What could be wrong? I just got home from eastern Washington almost home going up hills my turbo was winding up but losing power?? I need ideas before I take it to the shop. Before I get hosed from the dealer. Its time for a new truck. 2003 f-350 6.0. Frustrated...

Blowing smoke? Using or making oil? Can you hear anything abnormal, running rough etc.

Post by: jstone on September 03, 2016, 04:24:43 PM: Not blowing smoke, just turbo winding up and louder than normal and no power. I will check on the oil

Post by: Fowlweather25 on September 03, 2016, 04:31:47 PM: sounds like a boost leak. check intercooler and all boots as well as air intake boots and lines coming out of the turbo. sounds like the turbo is hurting for air which would cause the loss of power as well as the noise.

Post by: Jim/WA on September 03, 2016, 04:44:35 PM: Clogged air filter can cause the turbo to whine. I'd rule out the simple stuff first.

Title: Re: Diesel Issues
Post by: jstone on September 03, 2016, 04:52:25 PM: I will check the air filter but it is new as of spring time

Post by: b23 on September 03, 2016, 05:14:42 PM: I'd make sure all the hoses that connect the intercooler piping are connected properly and are in good condition. They can get old and split or just pop off and when or if that happens you'll definitely notice less power and more noise.

Post by: jackelope on September 03, 2016, 06:17:36 PM: Yes. Fix and recheck.
Title: Re: Diesel Issues
Post by: jstone on September 03, 2016, 06:32:54 PM: ok know another question take it to the dealer or who does quality exhaust work in the Tacoma Area. I love this web site!!!
Title: Re: Diesel Issues
Post by: Mark Brenckle on September 03, 2016, 07:03:07 PM: Personally I only go to the dealer if it's covered under warranty. Sorry I can't recommend a muffler shop in Tacoma.

Post by: jackelope on September 03, 2016, 07:21:34 PM: No dealership for exhaust work. I've had good experiences with Dan Fast. Is there one Down there by you?
Title: Re: Diesel Issues
Post by: Gsp90 on September 04, 2016, 08:32:11 AM: So did you fix the power loss issue? And for the price of a dealer or shop doing an exhaust you could buy a brand new kit exhaust from mbrp or diamond eye for way less (starts around 251 shipped for a turbo back

Post by: fernsjd41 on September 05, 2016, 01:24:47 PM: Exhaust leak after the turbo will not cause you to lose power in a diesel. I would check your intercooler hoses there very prone to come loose or split.... If anything you would probably gain power with your exhaust broke off, not loose power.

are there any sensors on the exhaust downstream of the break?

Pretty easy to do it yourself, I agree. I replaced mine last year with a Diamond Eye setup.

I also agree with other posts, this sounds more like an intercooler hose issue than anything. You are probably losing power because your turbo can't build up the pressure.

Not on that year of ford, the didn't go to the dpf exhaust system tell 08 with the 6.4l.

Post by: jackelope on September 10, 2016, 10:35:06 AM: I agree that the CaC tube issue is still the most likely cause but the exhaust needs to be fixed either way.

Title: Re: Diesel Issues
Post by: KFhunter on September 10, 2016, 11:16:29 AM: interesting you get full spool, loss of power and no smoke. Something is pulling back the fuel under boost. If it was a boost leak you'd see lot's of smoke as you're still full fuel but lacking air = black smoke

not familiar with 6.0's but I'd look for something that would restrict fuel - like mudman's theory of the EGR

Post by: Mudman on September 10, 2016, 11:56:59 AM: Check coolant. Replace egr or clean it carefully. Easy enough to do. Then drive it and see? Boost problem possible.Lot of times you can hear swoosh of boost leaks when under high boost. Egr common issue and you should clean/replace it regardless. Learn about these 6.0 so you can prevent spending 5000$ in the future, which will happen.
