Hello, most of the "easy fix" products that are supposed to seal leaks are just thicker weight oil.
That could possibly cause a lifter to stick because of the viscosity of the new addative. Thinner oils can leak faster if there is a leak, these companies offer products that swell existing rubber gaskets and thicken the oil offering a temporary fix that can add to problems in the future.
you are full of crap. you dont even know what a valve actuator is
I'm not the one who added a $5 can of snake oil to cause a $1500 problem. Good luck finding a magic answer.
