i tried searching but i know these engines are probably known for noisy lifters, but my 91 XJ 4.0 4X4 5spd has pretty loud noisey lifters when engine is warmed up. Oil is kinda of dirty (plan to change it soon) and the level is fine. Engine runs like a champ (170k miles) and has plenty of power. Is there anything to reduce the noise like some sort of additive or does anyone recommend a different grade of oil other than 5w-30 or 10w-30?
thanks in advance.
