I never had roller lifters... roller rockers, yes.
So, I tore it apart last night. Wanted to put it back to where it worked before I started dialing up the power. Very first lifter to come out was stuck.... destroyed by the cam. Ended up with 3 lifters destroyed. Stuck the camera down the lifter bore and the ok a look... the lobes look ok! Ran my finger over the lobes and they feel ok, too.
I installed the original hydraulic lifters and set pre-load as per the manual.
Today, I will change the oil and filter. Use break-in oil and run the break-in procedure. Change the oil/filter again and roll the dice!
I’m neither that lucky nor that good... but really, what’s the difference... if the cam is done, the engine has to come out anyway. At that point it will be a full tear down and clean.
