Turbo cleaning on an '04

[davegr1]

Well I did it, I dove in feet first and removed the turbo to clean it.. Never messed with one before, it was not as bad as they say. I read the article on "The diesel doctor" about tearing down the turbo. Mine was not that bad, 61000 miles the last 15000 on WVO mix.. The hardest part was getting the turbo back in, it didnt want to align back up.. (with the pipes). The vanes of the turbo were not pitted at all, and there was minimal rust. The unison ring was a little crudded, but emerycloth fixed that. Now for all you people that want to try it, Read the article on VGT re-learn, , I thought for sure I had not assembled it right, I started the truck and no turbo whistle, and mine was always loud...., with the K&N and the straight pipe!!. Ran right in got on the site and low and behold, the procedure was here.. Thank you Techs...... Now she runs like a scalded ape, which I guess is pretty freakin fast... Oh yea while I was in there I went ahead and pressure tested the EGT cooler, no leaks, so I welded the up-pipe with a steel plug. no more crap in the egt. No codes either, I like the '04s.. Next is a better fuel pump, the stock pump hates WVO.... But anyway, thanks to all who posted about the Turbo cleaning...

you wont make any boost in park..at least none of my turbos ever have

turbo chargers need load to build boost

Cleaning a turbo. WTF this is all news to me. Never heard of anyone doing this. I know of pick-ups with 250,000+ that never had it done. My dads last dump truck had 700,000 and never had it done. .


What is it going to do having a clean turbo??

nothing..as long as you mash the go pedal your turbo is clean..turbo "reconditioning" is basically taking it apart and cleaning it out..problems such as sticking veins, ect.

i have never cleaned mine other then putting the pedal down

hmm guess I read wrong then. Any easy way to tell if the veins are sticking?

one way is by looking at your boost gauge and if it shows low boost or the truck/turbo feels laggy then you could have a problem there.

What is low boost? Mine on hard acceleration is 20-22. I just got this 05 and am not sure what is right and wrong. I read somewhere that you can unplug the connector on your EGR valve. I did that and my truck runs better but my boost is about the same. I have 75000 miles on it and want to fix anything I can while under warranty. Your advice is appriciated.

I HAD AN 05 6 SPEED THAT WAS MAKING 34 TO 36 PSI STOCK, HOPE THAT HELPS

The vanes can stick and cause an overboost almost as easily as causing an underboost. Over 30 psig stock sounds too high to me.

The Variable Geometry Turbo is wonderful technlogy - until it fails. This is why things like buying clean fuel (and proper fuel filter maintenance), minimizing idle time, occasionally driving it like you stole it (after it warms up), ccv re-route, EGR delete, etc. are all good things to do.
