6.0 turbo Problem.

[dlsanders6oh]

So my friend just bought a 2005 f-250 fx4 with 124,xxx miles. He come's over and i hook my edge cts up on his truck to see if the truck has any problems that we can see from the edge. Everything checkeds out but... just the turbo acts like its having trouble building boost while we are driving the turbo will lose all boost and come back with in sec's. it dont matter if we are just driving @ 70 or just taking off we are going to take the intake off and check the turbo wheel tomorrow to make sure there is no play in it. But there is no codes, all the hose are tight, checked the air intake to make sure its not clogged up. It might just need the turbo cleaned out.

Turbo may need to be cleaned, have ran into that surging issue before being the unison ring siezed to the CHRA and the impellar housing was warped when i replaced the CHRA and when i put the impellar housing on wouldnt go over the impellar blades. Make sure the unison ring isnt cracked. Pull the vgt solenoid out and see if the tip that pushes the eccentric inside the chra has a ridge worn into it or binds up when you push it in. May just need a new vgt solenoid as well.

Check the EBP sensor and tube for being carboned up. Get some BG intake throttle body cleaner spray it down the tube use a pipe cleaner and get as much out of the tube and use about 5-10 psi regulated air to blow the sensor after spraying some intake cleaner in that.
