Is there any shaft play or are the blades messed up any?

 

Dont know I was too pissed to look. I'll probably take a look tomorrow since i'll have nothing else going on. I'm literally sick to my stomach with that truck I cant believe how its one thing after another.

 

I know exactly how ya feel. Been through the same thing with mine, so pissed at it I had it for sale for a few months actually but I knew I would miss it if I would have sold it.

 

Well sure as hell I went upstairs to my wife and told her its for sale. I'm tired of being let down with this damn thing. I wouldn't be half mad if the mileage was good when it was running, but since I got it tuned and did all the work to it I'm getting 4mpg LESS on the highway than stock w/ a 3yo fuel filter! So what exactly could it be then? I'll check for shaftplay and the impeller tomorrow. But what else? Doesn't appear to be any boost leaks.

 

You can't "look" for a boost leak... You have to pressurize the system and inspect all the connections around the boots... You should try to post in one thread insted of multiple ones that are on different things that all turn into the same thing.

 

I'm saying there are no obvious boost leaks thru couplings or anything. But I dont foresee any boost leaks magically popping out of nowhere that would cause a zero-boost situation

 

if the turbo sounds like its spooling and theres grinding noise, then the turbo seems to be ok. make sure on the bottom boots by the intercooler they didnt blow a hole in the bottoms. or something. if the turbo sounds fine, it should be fine. you obviously not getting the air into the manifold, and it wouldnt hurt getting new upgraded boots and clamps anyway.

 

Ya no noises yet. I'm checking the imp shaft and blades tomorrow. Also gonna check the flanges for proper fit and secure and dtuff like that. Gonna check stuff and report back to u guys. I'm sooo pissed tho this second turbo better not be fried.

The impeller shaft still spins. Checked for obvious boost leaks again, nothing happened. Truck doesnt smoke TERRIBLY like it did the first time I friend my turbo; I can drive down the road and not smoke too bad. But as soon as I hit 1800+rpms it starts sputtering and popping like crazy. All the flanges are tight. Afc is looking good. I have a line going from the intake manifold to the afc, so the line from the afc to the wg is staying capped.

Somethign I noticed when driving it today. The turbo is NOT as loud as it was, and when I let off the gas the air doesn't "woosh" back into the intake.

Another thing I thought of was even when the truck was working right, the first cold-start of the day if I gave it too much throttle around 1800rpms or so it would pop and sputter real bad until its driven for a few miles. Dunno if its relevant or not.

 

when mine is cold it will kinda pop and sputter if i rev it up to, did you check for a pre trubo exaust leak?

 

yep checked there everthing was good to go. Only place thats obviously leaking is the vband right before the downpipe.. but thats after the turbo so it doesn't matter
