So I have 2 lifters that won't bleed down as I roll the motor over and I'm wondering if this goes away after seeing oil pressure. I can put my cam in the position that will open the valves and in 15 minutes or so they will compress but when I roll the motor on over to let those valves close the lifter will "expand", holding my exhaust valve open. Is this a typical thing on these or what do you guys think? See my pictures and thanks, I don't want to install the engine if they are going to hang open. This is only on 2 lifters, the rest all bled down and are fine. ???
