wastegate problems

ok i know how it happened the guy that had the truck before me hauled heavy oversized loads all the wind resistance caused the waste gate to work full time. the turbine half of the turbos hole for the wastegate valve is wallowed out, so the wastegate valve fits loosely and there for is impossible to close (no boost untill about 3000rpms). so anyway i want to replace the turbine housing but i cant figure out how to get the daggum thing apart anyone have advice or a breakdown any help would be appreciated. thanks in advance.

im pretty sure you have to remove the turbo to put on a new exhaust housing

thats a totally new one on me but if you say so.. pull the turbo and its then odvious how the housing comes of you need a 12 point wrench 8mm if i remember right pop the ebpv then then the housing

did you try tightening the wastegate rod in 4-6 turns or so i think id try that first

well i have the turbo off, all the bolts are out, and im wondering if i need to pull out the wheels. is there a trick to it or is it nessessary. the turbine housing where the wastegate fits is badly wallowed out. it has 494000 miles on it. and thats my lower milage truck

no need to pull the wheel the housing will slide off over it

ok i decided to adjust the wastegate as much as possible. i got about a quarter turn when it snaped off. good thing i have a 115v welding machine i got it patched up. now im just having trouble aligning the turbo with the exaust flange in the back. but i'll get it tomorrow i appreciate the help guys.

wow not heard off snappin one off ?? the exhaust flange is so much easier if you take out the bolts that hold the pipes to the manifold do the flange then bolt the pipes back to the manifold
