Thanks a bunch! I had my oil changed and
had an additive put in the oil which
is supposed to clean out the valve train.
It went quiet after about 5 miles. We'll
see how it goes!

In case that doesn't work, I may try the
injector line idea. Do I loosen these
at the block end of the line?

I'll run a dose of Techron through the
system at the next opportunity.

Thanks again!
