Is this a sign of turbo vanes sticking?????

[travisH3]

So i was on the on-ramp to the expressway behind some buick about to merge onto the highway doing 45mph, when i checked my mirror i seen a semi hauling tail and im not one to try to tick those guys off or get in there way so i gave it some throttle to get going and change lanes to clear the way and when i gave it gas it didnt have alot of power and i look down and have 0psi on the boost gauge. as i kept watching it, i was still kinda into the throttle then, boom back up to 8-10ish psi cruising.

is this a sign my vanes were stuck for a second and me giving it throttle unstuck them. i have no problem blowing the system out to break up some of the carbon build up. i love getting into the throttle and hearing the rumble so thats why i dont know why they are sticking
i have no smoke switch, hardly ever blow smoke.
let me know what you guys think. Thanks

Sounds like it to me. Run sum cetane booster if you haven't already. A can of seafoam in the fuel tank may help also. Maybe run a super heavy dose of cetane booster and get on the highway and really rip into her. That should help break anything up.

I'm running centane booster now I will get on it tomorrow heading to school. I might try the heavy centane as long as no one says it's bad or not to do it.

mine hung up once at like 15psi after i was deployed and truck sat for 7 months.... i pulled over, shut it down, figured a boost hose blew off... couldnt find nothing, fired it back up got on it, no problem ever since. I told that to dealer they said stuck vanes, drive it like you stole it

the cetane booster wont really do anything if you over dose it, its safe its just a waste of money

[travisH3]

ok, then i wont do that. lol

Even if you are not blowing black smoke it doesn't mean that you can't have soot build up in the track the vanes run in. If you want to be sure you can disassemble the turbo break it down and clean out the track and the vanes. But before I would do that I would check the the piston that advances and retards the vane is working properly.

ya i know it still builds alot of soot, i mean my new exhaust had a pretty good coat the first week i had it.

but i got on it a few times today and it never had any problems. i couldnt get it to do it again. if it happens again im gonna break the turbo down and do some cleaning on it.
thanks

maybe try 405 Fire Power additive. it's one of the strongest fuel additives out there. i use a qt a year just to keep the fuel system clean. also maybe REVx or HSS could help. but be careful because when your turbo sticks it can over boost and pop the head gaskets and over spin your turbo. also some turbos can be cleaned depending on the state of how stuck the veins really are. but yours sounds like an underboost situation... have you checked for any codes?

[travisH3]

Ya. I tried pulling codes. It came up with p0341 Which is cam position sensor but I have had that since before my ficm went bad. I told the dealer about it and they basically said don't worry about it. No other codes.

How can the truck overboost. I figured that could only happen if u had a aftermarket turbo. How does a stock turbo overboost. Thanks for the reply
