I tried them all - MMO, ATF flush, engine flush, resealed the oil pump, i even replaced one of the lifters cause i was doing the head gasket and it was questionable.
Sometimes it worked for 10 mins, sometimes for 3 days, and sometime it did JACK S*#T....
and then i found the BEST junkyard ever.
I got 2 oil pumps (more is always better), a muffler, some t-belt covers (not that i run with them anyway), many odds and ends, a strut tower cross-brace (or whatever its called), and a headlight case all for $30 - and that's canadian eh!!!
Threw on the oil pump and drove it hard for 10 mins - oil pressure up and lifter noise gone bye-bye. HAPPY HAPPY HAPPY. Needless to say I'll be going back for more since he has 3 soobs ripe for the pickin.
