I like to use MMO on the cam/lifters/etc of a car that has been sitting for a while that I'm preparing to start. I also had a '72 Bronco with pretty severe lifter noise that a pint or so of MMO completely silenced. Of course, your results may vary, and you don't want to use it to "quick fix" a potentially serious problem. Mobile 1 should give you similar results, so if it didn't fix your problem you might need to dig deeper into the cause.
