The whole front of the motor just had to be replaced that last time this POS craped out. So there maybe a loose bolt from that. It has the original Control arms too, so if y'all are not pulling my leg about that, they could be going to too. Just really looks to be coming from the front cover.
My money is on the previous front end engine work inducing a leak. As for LCA bushing, yes they are oil filled and can leak when they wear out. The oil is a small dark oil drop just inboard of the tire. Worn LCA's feel like a clunk in the suspension when going over speed bumps.
So since I never Follow up with whats was wrong and if it was fixed... The leak was from the front cover. LR fixed it as they just had that all pulled apart three weeks ago when they rebuilt the front of the motor.
