Comp cam lifter problems.......what lifters?

Does your oil filter have an anti-drainback valve? We used to see this 'noisy lifter on start up' complaint at the Ford store I worked at in the 90's... a Motorcraft filter usually solved the problem.

The only time I ever had noisy lifters is when I insisted on using adjustable lifters on the '57 olds I drove in high school...1965. My boss told me not to use them but I knew better...at 16.

Not...
