I assume that the engine has good oil pressure when it is warmed up. For a short fix add one large (or two small) can of STP to the motor oil. This should be done with the engine running and preferably warmed up. Beyond this, it will require removing the lifters and determining their condition. Start with the STP and let us know if that cures the problem. If not, then we’ll go into detail on servicing the lifters.
