1992 Dodge Caravan noise in lifters

Mitsubishi engine? (Overhead cam). The lifters in those should really be replaced all at once and the rocker arm assembly should be inspected very carefully at the same time. Once disturbed, they tend to not want to pump back up, especially at that ileage. Have also seen the holes where they ride in the rocker arms get worn too much for oil pressure to stay behind the seal. IF it's a Dodge engine(pushrod) remove valve covers and take a look, have seen a bunch of them break the rocker stands right off the cylinder head
