Hi Stan:
Thanks for the ideas and the quick reply.
As far as I know I have hydraulic lifters (original 82 2.0L engine with 51K
on it). Given the ambiguity I have with Boston Bob's method, I will try Tom's
and see how that works. In general which is the best to use with old possibly
leaky lifters?

Would I hear this as I tightened the adjustment screw or when the engine is
warming up after the adjustment?
