So I installed a used turbo which apparently wasn't in as good of a condition as the seller said. Anyways the car ran fine for a day and then while I was adjusting the VNT rod (car was idling) the turbo seals blew and resulted in a run away engine. It took me about 30seconds to get the car stopped, but because it was sitting in neutral the RPMs went through the roof. The motor drank about half of the oil, but didn't run completely out.
I installed a new turbo and got the car running again, however it doesn't run the way it used to.
Symptoms:
Upon first starting, the car wouldn't rev above 3k. When it hit higher RPMs the car would shutter and then idle very rough...almost felt like it was running on 3 cylinders. Also, lots and lots of smoke. After running the car a little longer and revving it I got the engine to rev up to 5k, but its by no means a "smooth" transition from 1k to 5k. A lot of times it'll get "stuck" at around 3k and then if I let off the throttle a little then hit it again the motor will rev very fast to 5k. The last straw was when I looked under the car and saw oil coming out of the downpipe, not a lot, but enough to make me concerned that there is some serious engine damage. Since I got the motor to rev to 5k or so, the smoke cleared up considerably.
Also, when everything cleared up for a little bit I attempted to drive it and there is no power at all...feels a lot like a dead maf (vag-com says maf is fine).
I'm thinking the high RPMs might have killed the injection pump along with bending rods/valves in the engine.
My current thinking is get a long block and when I have time rebuild the messed up motor.
Thoughts?
