The oil cooler lines are on the opposite side of the engine from the exhaust, so it shouldn't be a big deal. Mine seeped for a while and just ended up on the front differential. As long as it's not dripping on or near something hot, I wouldn't worry much about it, at least from a bursting-into-flames perspective.
