Need some advice 4.0 engine running like crap

[Todd~Rod]

Ok so my 4.0 has been idleing a little rough the past few thousand miles i didnt think anything of it and now its really sounding bad and not running right. there is coolant leaking down the front of the engine i believe its coming from up top but not positive where. should i replace all the gaskets on the top end? its a 96 and i dont want to put alot of money into it because i plan on selling it but i dont want it running like shit either.

Get a flashlight and look where it's really leaking.

Find the trail and look all the way up, see where it originates.
