From a frustrated 944 owner to you engine builders. Alu dust in crank case.
I bought an expensive "no-fault" 944 turbo this time last year which quickly lost boost. Turned out that a washer had entered the intake and was eating my compressor wheel. This, combined with the need to change all things rubber lead me to pull the engine.
I finally installed the engine a couple of weeks ago and have been on a few very short drives since then. When checking the oil I discovered a gray residue/coloring on the wipes. I first thought it be traces of the assembly lube, but today I discovered aluminum dust in the intake plumbing and crank case vent pipe. Turns out that my turbo has decided to eat itself again. This time the compressor wheel is grinding itself to bits on the housing.
I have owned this car for a year, and have driven less than 200km. Apart from this problem the car is faultless, but this setback has me considering selling it as a project. I understand that I need to drop the engine again to fix the turbo, but please tell me there is a quick way to flush out the dust other than taking the engine completely apart to clean the galleys and crank case.
