Alright guys, Im kinda baffled whats wrong on here.
Recent work done by Diesel Mechanic:
New Cam
New timing belt
New OEM Turbo
New Fuel Filter
Problem: (No Boost)
Turbo makes high pitched whining noise at idle, Compressor wheel will stop spinning while engine running, you can turn it by hand (I know dangerous, haven't lost a finger.) If you remove the vacuum line going to Actuator, the turbo will start turning again and there is a lot of exhaust pressure that releases.
Things Ive Done:
Checked all vacuum lines, Source vacuum all the way to N75, Pulling 22inHG at idle, at actuator and source vacuum. Smart Actuator holds vacuum.
Blocked off EGR At egr Valve near asv
Pulled exhaust out, Exhaust is clean, still removed for testing.
Checked all boost hoses for leaks, all super tight
Zip tie mod.
Triple checked timing, everything seems to be perfect.
Turbo shaft feels tight. spins easily by hand.
