I know these engines have valve noises sometimes after 100,000 miles, but
mine is wierd.

Some times it makes a very loud tapping noise like the whole F'n engine is
coming apart.

Other times it runs so quiet its like brand new. NS.

This vehicle has 128,500 miles on it.

Do you think I need a new engine?
Is this engine likely to STB and leave me stranded?
Or do they go like this forever with no problem other then the tapping
noise?

thank you,

Tom L.

damn! something dropped down in it? could be demons, but sounds like
something is in there that shouldn't be. On the other hand, I've had
extremely noisey engines that knocked and banged for 30k miles and more. But
if it's not consistently obnoxious, I'd venture to guess there's something in
there that shouldn't be or something that isn't where it belongs.

It sounds like you have one of the old mechanical lifter models that
need adjusting. It would be a good idea to adjust them and clean the
oil returns.

Agreed. But could the poster have a 2.8? I know Ford was trying to
unload those old mmechanical 2.8's and put some in pickups and
Aerostars. That was a crime to make somebody adjust them in one of
those Aerostars.
