RE: Turbo problems
I recently wrote:
> I have a 1990 Audi 200 Turbo. [snip] It appears as if the impeller on
the turbo doesn't spin.
I then asked the following questions:
>>1.Is it possible to soak the turbo to remove the oil deposits?
>>2.Would an oil change with synthetic oil combined with an
aftermarket additive to remove deposits help?
>>3.Would a few light taps on the turbo cause the impeller to
break free and spin?
Here are the results of this weekend's work:
Soaked the turbo in WD-40.
Gently worked the impeller until it broke free and spun.
Changed the oil with synthetic.
Max boost as read on the on-board computer:
Before turbo problems: 1.2 bar
after turbo problems: 0.7 bar
after this weekend: 1.3 bar
I still have to change the oil lines feeding the turbo and I'm planning
on replacing the turbo with a re-manufactured one because I don't think
my band-aid fix is going to last all that long. A minor success,
