Just in from the garage, girlfriend is up on jack stands and I sure hope I'm wrong about the source of the leak.
It's definitely from the right front of the motor, not the oil pan.
The drips are coming from under the lower control arm area.
The radiator hose is wet as is the top of the mono spring so the oil is coming from somewhere above. There are two oil sensors, one under the oil filter and another in front and to the left of the oil filter. They both appear to be dry, but honestly, it's really hard to tell. There's no room to get a hand in there, especially the one under the oil filter.
There's crud around the oil cooler lines, a smoking gun for sure. I've wiped away the gunk with paper towels and tomorrow after work I'll fire her up and run her until she's warm. Then I'll clean the area again, if there's a leak there it should be obvious.
So, I guess the question of the hour is, what do I do if it's the oil cooler lines? The lines themselves look OK, I didn't seen any cracks in the rubber. Would it do any good if try tightening the fittings at the block? I guess it could be coming from where the metal ends are crimped on the hoses, if that's the case then I guess I'm screwed. I seem to recall that the oil cooler hoses are "Unobtanium" these days.
Ideas? Anybody got any good tips?
