What should I do if my Mopar lifter makes noise?

Whether something got into the lifter because of more ‘cleaners’ in the new oil or who knows what reason, I would pull the valve cover and inspect the rocker arm, pushrod and valve tip just to make sure there is no problem. Or, do an oil/filter change back to what you had been using and see what happens. Keep us informed. Good luck.

How do you Prime a Mopar 440 lifter?

Using a wooden dowl rod, I work the piston to allow the tappet to draw oil into itself (pump it up). Simply fills the tappet cavity with oil. Sure, some will leak out, but it’s primed before it goes in the motor.

What should I do if my valve lifter is making noise?

Flush out the old oil. Unscrew the cap under the car and place a container or bowl under the cap.

This is probably the best solution to avoid noise from lifters.
