By open I mean it was stuck up, on high cam lobe position, leaving the valve open.
It will now tap back down but stays back up when acted upon by the cam lobe.
Yes, I do believe he was pumping a dangerous mixture into the tires.
(Just having a discussion about that very thing.)
Valve and side covers are off and painted, lifter hosed down with P Oil, waiting game started.
Is there a specific method to safely pull a stuck lifter without tearing down the engine?
