Turbo going bad.....i thinhk

[strokin444]

I have a 2000 f-250 and im only getting 21lbs of boost with a dp 140 hp. And my milage is going way down. My friend said the turbo might be going bad but i dont want to buy a new after market one. I was thinking about rebuilding mine and up gradeing it. I was wondering the best way to go about that. thanks

You can inspect the shaft to see if there is play in it.. Just pull off the intake side at look at the wheel for damage and the wiggle the input shaft.

I took off the intake side and tried that and it seemed fine. Should i take of the exhaust side?

no... move the intake side in and out and side to side.


If you're building 21lbs you don't have a broken shaft.

Thanks. I will check it better this weekend, i checked it about a month ago but it was a quick check.

You have some other issue. Your turbo seems fine to me.

any ideas on what it could be. I also think i have a bad ehaust backpressure sensor could that have anything to do with it.

make sure the ebp valve isnt stuck closed , may be open with engine off , but after started ive sen them close off even partially when running , if you have a ad ebp sensor which is common for the 7.3 , just unplug the ebp solenoid at the turbo and dont sweat it , see if that makes a difference

Thanks. I will check that sensor tommorow. Where is it on the turbo.

I believe he is saying to unplug it at the pedestal that the turbo sits on. The plug is on the front side of the pedestal held in place with wire clip.
