I have a '95 XJ with a 4.0 that has ~287k miles on the clock. For a while now, I've had a clattering in the engine at higher RPMs. It seems to come in at ~2500-3000 RPM but hard acceleration seems to help until ~3500-4000 RPM. It will linger down to ~2500 RPM when I am off-throttle, decelerating.
My initial thought is lifters but wondering if there is anything else worth checking? (probably because I don't want to pull the head again) The motor seems to run hot based on reading the plugs (probably lean since coolant temp is never an issue) but it doesn't seem like a pinging situation since it happens on decel and cruise.
