My turbo is broken. PLEASE help.
I got turbo troubles. This is my Daily Driver and I have to be able to get to school and work, so I need to know what's wrong and how to fix it, if it's cheaply fixable.
Symptom: massive turbo lag, max 12psi of boost. (Pre-cooler), barely any freespin and 7mpg city. NO surging (has not surged).
I thought maybe it was the exhaust leak where the y-pipe meets the turbo that I hadn't fixed yet.
I got the intake stuff off and checked the intake turbine and it's goin "clank clank" fore and aft. So I removed the whole turbo to inspect it and will probably be putting it all back together tomorrow in the rain, if I can or can't fix it.
It has about 1/16" of endplay, the fins are in pretty good shape on both sides. No oil in the exhaust housing. And the exhaust wheel has the same endplay, they're moving together so I don't think the shaft is broken.
Also it doesn't spin very well. I hear a funny noise in the middle when I spin it, dunno what it is, but if I flick the wheel with my finger it only spins for barely a second on its own.
So turbo wizards what does this mean. Do I need an $80 WW or a $2-3k turbo... in which case I will be parking or selling the truck.
