Ive heard that using the exhaust brake even without a trailer helps keep the vanes and ring clean but i do not know if that would help you if your stuck at 51% with no range of motion.

You will definitely want to fix that, I ignored P2563 for a couple years with no issues, the third year I got to my destination with my 28' gooseneck and 8000lb load, truck had no power, if I tried to rev it up, it blew alot of black smoke. I don't know what position my vanes were in as I did not have a way to look. After it cooled down, it ran fine, dealt with that all summer. I replaced the turbo, figured I was there, why take a chance, I did split the old turbo, the unison ring was seized to the hub it sits on, pried it off, cleaned the hub of rust, I believe if I had to use the old turbo, it would work.

Definitely want to fix that. I'd pull the stocker and clean it up.

 

[Steve54]

Replaced turbo pulled the old one apart and the unison ring was cracked and the housing pitted
What a difference the new one is
I went with a new unit as it was a big job and didn’t want to do it again using a repaired one

Glad you got it fixed, that was my theory, and too did not want to do it twice.

Wynn's Turbo Cleaner

Anyone try Wynn's Turbo Cleaner ? The advertising says that is does clean vanes, not sure how.

 

[Steve54]

Mine was pretty clean inside and no amount of product would have fixed the cracked unison ring and pitted housing and travelled 460000 klms
Full performance restored and came with new boost control and vane position sensors
Glad I got the new turbo

good to hear you got it fixed

For those who now more than I do (which is most of you Im sure) I have a question about his Turbo.

Which came first, the stuck vanes or the cracked ring?

The reason I ask is to see if keeping the vanes clean, with Waynes or some substance like this would have prevented the ring from cracking:

In other words, would cleaning the turbo with something like this be a good Preventative Maintenance procedure.

I have a 2011 LML, the vanes stick just every once in a while, should i go ahead and get a new turbo, and how long for an amateur to put one in

You may consider this first to see if it works for you:

Cleaning vgt turbo, I did it!!!

Well I've been noticing the vanes on my truck seemed to have been sticking, slow throttle response lots of smoke and laggy. I planned to replace the turbo, but figured is try cleaning the vanes first, the worst that could happen is it still ran the same. So I started by going to the parts...
