I got my lifters and they got a little note in the box that says they are not suitable for extended periods of idleing.. It says pin oilers required for that... Is this true? Im guessing They wont see enough oil splash to lube the bearing at idle? seems kinda far fetched at the cam has oil just pouring over it.. Do i need to send these back? im using NON oiling push rods if that is a factor? .680 lift, W 1.6 roller rockers. Thanks again.
