Water in oil/brown smoke

[Joshua Van tol]

It does work, but only for relatively loose pilot bearings. It works  
rather better on larger bearings (such as the fully sealed bearings  
used on some Saabs) where there's lots of surface area.

For the audi pilot bearing it probably won't work most of the time.  
But it's quick to try it, so why not?
