I recently took possession of a 2001 Avant 2.8 with 120k miles. The car had been sitting for a few days and I noticed a little bit of bluish smoke at initial start up which disappeared after about 5 seconds of run time.

A fair assumption would be its about time for valve seals. While I'm doing the valve seals, does anyone think I should consider springs also? If so, what makes are recommended for seals and springs?

I plan to do the whole timing belt routine along with the waterpump and any accessible seals, including the main crank seal. Since the timing belt is one of the more important items, I'd like to get some recommendations on what folks think of what make of timing belt would be best.

Wait , there is more.........remember this has 120K and from what I can tell the engine is still very strong and shows good compression from tests.

I'll be doing the work myself. So, while I got this beast apart, what sensors do folks recommend I replace?

I defer you more experienced Audi owners.

 

for timing belt visit blauparts.com. as for the blue smoke, i get the same thing. the only sensor i recommend changing is the ECT which is right behind the passenger side head. make sure you document what you did and do a writeup.
