Looking at what attention my 93 cherokee may need to survive another year of DD abuse/weekend wheeler. I drive all over, 3 hours to school from home, 4 hours to visit GF, and trips to beach and mountains every other weekend. So this jeep sees a lot of highway. Transmission was recently serviced and has a large cooler on it. Entire cooling system was replaced last summer and the engine internals has remained untouched at just around 168,000 miles. Still runs like a champ and never ever thrown up any codes or nothing. Obviously it has developed noise over time and I can hear ticks and just the loud low sounding knock. I was planning on replacing the valve cover gasket since it looks like it is starting get really wet with oil. If l go through the process of replacing the valve cover gasket should I take the time to go any deeper into the engine? I took a video and have tried to captured some noise. Does this engine need any attention or should I just keep on trucking? :driver:

first your oil pressure looks to be reading too high... you should put a manual guage on and check it the sending units . secondly the noise in te video sounds like the rockers are dry.. you may need a new oil pump. the valve cover gasket will help as oil is much better IN the crank case.lol but before you do any gaskets u should be sure ur getting good oil pressure.
 
Does the noise seem like its coming from the valvtrain or bottom end? Could just have some clogged push rods. Cheapest and easiest thing to do is an engine flush with kerosine.
