this is probably too general of a question, but i'm not very mechanically inclined. anyways, when i start my XJ, it has a pecking sound for about 2 seconds. sounds like it's in the top of the engine. if anyone can steer me in the right direction, it'd be greatly appreciated. it's a 92, 4.0, 184,000 miles, hope that helps.

and its done it since it was new. :wave:

your lifters are worn, there filling up with oil for those 2 seconds and your push rods are making that sound slapping on the valve rockers.
once the lifters have oil in them noise goes away, all is good but for those 2 seconds you have no oil in them so wear will be more prominant in them.

Yeah, ALL Jeeps make noises! I had an XJ w/ about 60K on the odometer, and it did the same. One w/ 88K that never did. Current XJ has 214K, and does it only when it feels like it! All I know is that they will run a LONG time if you take care of them. :thumbsup:
