How do you know if you have a bad hydraulic lifter.
Is there any way to easily test them?
I had the head shaved, valve faces recut and new guide seals. The engine still has a stumble and misfire thing at idle, and even if you hold the revs up higher.
So unless I have a cracked piston, broken ring lands...(but compression was good last time I checked).......I can only think of lifters.
When the head was off I gave all the lifters a very good cleaning, I was hoping that one was gummed up. But they all looked really good for the miles on the engine.
My lifters look like these.
