Just did an intake and plenum repair with hughs kit on my 99 durango 5.2. noise went away and hesitation, but now I'm leaking oil from harmonic balancer. I drove for a while and everything was fine for about 20 miles then my temp went just above 210. pulled over immediately and let it cool, checked fluids. levels and colors were good. started back up and ran at normal temp for the 15 minute drive to my buddy's house. looked it over and looked fine. later on my way home it started squealing and oil pressure dropped for about 5 seconds. I pulled into a gas station and oil was dripping out pretty good. did I screw something up to cause this? and what steps do I need to take to fix this?

 

Clean it up, and then run it for a few minutes. (check your oil.....) Likely its just the front main seal that is leaking. Not to bad a job to change.
