[Vwdiesel] injector leaks

[James Hansen]

Nope, not thread sealer.  Use antisieze or other antisieze type product 
on the threads, such as graphite.  Bubblies as you see are from the 
bottom of the injector not seating on the heat shield, which more or 
less doubles as a gasket, the pressure escapes through the threads. 
Shitty deal is, over time, carbon migrates into the threads along with 
the combustion chamber pressure.  If there is no antiseize present, it 
makes the injector threads and the head almost become one.
