BreakOut

Well my jeep is defiantly a champ. Running great but now i need to fix the oil problems im having with it. First off is the oil pressure. Im holding around 10psi at idle and at almost 2000rpm going 55mph to 60mph im only holding 20psi. Now this is all oil pressure just to clear that up. Im wanting to know why and if this is normal that my poor jeep is like this? And now the second problem. What is the most common leaking points of the 4.0? My jeep is currently leaking 1 quart of oil in about 5-10 days. Its getting worse as the days go by and Im getting sick of seeing her like this and i want to get her all fixed up and running greater than she is. Any help or links or guides leading to my repairs needed would be amazing!

Thanks guys!

They pretty much got it. You could also check around the oil pan gasket. Go get yourself some of that dye you put in your oil and a blacklight... It will make things easier.
