My turbo seized up last weekend, removed it and had it rebuilt, cleaned the inside of the intercooler, all the intercooler pipes, the inlet manifold, the inlets on the cylinder head, the EGR valve, the turbo oil feed and return pipes, oil breathers and all associated holes that go in to the block. Put it all back together, primed the new turbo with oil fresh oil and filter. Test drive started out alright, but then started struggling setting off, foot flat to floor in 1st gear and it bearly makes it to 2500 RPM. Same symptoms as the seized turbo......gentle drive to get it home praying to the big guy in the sky that the turbo hasn't gone again.......on closer inspection it hasn't phewww. What else can be causing this lack of power? Anyone know how the turbo vacuum solenoid should work? Any help could be greatly recieved as I'm at my witts end with it now!
