I have a 88 GT 308N/A.with Motorsport 1.72 stud mount rockers.Every 3 runs they start tapping like crazy.4 times i adjusted them and 3 runs is all they last.Im thinking its got 2 be a bad lifter.Just ordered new lifters and pushrods.Anyone else have this problem or know the solution.Also i marked the rockers last time i adjusted them and everything is in the same spot but they tap like hell???
