The earlier years of this model had trouble with lifters that failed
at relatively low mileage. The lubrication passages in the head were
too small, and there was probably a design problem with the lifters
themselves. If you're lucky, a switch to synthetic oil - with the risks
of oil leaks developing that this entails - will solve the lifter
problem.
If not, you may be looking at new lifters, down the road. And no, I
don't
know exactly what the design fix was. Maybe someone else here does.
