[ba] Mystery fluid leakage -- '04 A4 1.8T

[Arun Rao]

Folks,

My son's 2004 A4 recently started doing two things, which *might* be unrelated:

* Dripping clear oil 
* Losing coolant

Both of these things started happening soon after he changed the oil and replaced the stock exhaust with a Magnaflow. 

The oil seems to be very clean, almost clear, but with a slight pinkish tinge to it. Is manual transmission fluid pink? Never heard of it leaking.

We've checked for obvious leaks (engine oil, brake and hydraulic fluids -- none of which are pink anyway), but found none.  None of them are particularly low, except for the coolant.

The timing belt was overdue (96K), so I had it changed along with the water pump, but it looks like we're still losing coolant.

I'm baffled. Any tips would be appreciated ...
