headed in for the oil cooler again. this time i was smart enough to take off the wheels and drop the Jeep to a more comfortable working height! last time replaced it was around 100k miles. i'm at 161k now, so doing plugs again too while in there.

it appears the actual heat exchanger was separating, which is not a common failure from what i've read. it also seemed to be leaking either from one of the plastic plugs at the front, or that bottom seal. both of which are typical issues.
