95 Trooper 280,000 runs great but time for new engine?
 

Hi
My 95 trooper has had the outer lifters changed and the ticking got quieter but periodically gets worse thinking of trying the oil drain technique but if doesn't help I'm thinking of either changing the rest of the lifters and rocker arms or getting a new engine .. It runs great with pick up but not sure it's worth it at 280,000 mi (mostly all interstate mi) Any help is much appreciated:)
