BTW, I always found that a bottle of Marvel Mystery Oil in the oil of a
10V or 20V I5 worked wonders on quieting down noisy lifters. I would
usually pour it in a couple of days before an oil change, run it a
little while, then do the change with nice fresh oil of the proper

Kept my 20V purring along for many miles.

Both common symptoms.  New rubber (not cork) valve cover gasket is about

$20; the nuts must be torqued very gently or a new one will leak, too.

An oil change or two might quiet the lifters down a bit, if you really 
can't stand it, they're about $60 or a set, and not too bad to replace 
if you're used to "inside the engine" mechanical work.
