I replaced my cam tower gasket last week and it took me about a month to do in my free time. During that time the cam tower was sitting off the car.
I reassembled it last week and the car sounded awful with a lot of lifter noise. I ran it until warm a couple times and the sound didnt go away.
Yesterday I got some Marvel Mystery oil as recommended here. I ran it until warm and then drove it about 500 feet. Suddenly the noise went away and the lifter pumped up.
So the stuff worked great for a lifter that wasnt pumping up. I wouldnt want to keep it in the oil long but it worked.
