Got an issue with my turbo......probably self inflicted.
Our September trip went well but ended up with a brake problem where the rear caliper was hanging and caused enough heat to melt the seals in the caliper and losing brakes completely. The car was running great up to that point and when I realized that, I stopped the car and the brake rotor was glowing red and so was the turbo housing. I let it cool down and then limped it back to camp with no brakes.
So we just went on an October trip........I fixed the brakes and changed the oil. Made sure I had good oil pressure turning the motor over before ever firing it up. Upon taking it out for the first time, I soon knew there was a problem. The turbo made some squeaking noises and would not boost. I got out and looked things over and the housing was glowing red.
I removed the turbo and took it apart and it didn't have any indication of rubbing but did seam to have a slight catch in the rotation so I took it apart, cleaned up the shaft real good and installed a new bearing assy and it still screeched at rpm. I had already double checked and made sure it was oiling (gauge said 80psi) and the AFR looked good as well.......starts and runs fine.......the rotating assy just must not be free enough to spin correctly......hence it turning red.
So AFR is good, temp is fine, oil pressure is fine, drain line is fine.......did I screw something up with it when I got it hot while driving with my brakes dragging?
Any info on trouble shooting is greatly appreciated!!
