How long can a turkey gobble before you damage the water

[Jonathan Monetti]

Thanks Dave.  I actually used this technique (thank god for the archives),
but I didn't have the stones to do it while the car was running--a little
tapping, start her up, a little more tapping, start her up again...

Seemed to help the gobble, but now I'm looking at the the tensioner and/or
pump (same sound as a failing bearing).  Maybe bad from the beginning or
maybe ruined from the original TB tension. 

Again, thanks!
JM
