Yeah, the cam cover gasket was changed about 10000 miles ago, so were the cam cover nut gaskets. I checked around the head and I don't see any oil leak there. I wiped off and cleaned the oily area thoroughly and ran for about 30 min and nothing happened. Then I drove 2 hours next day and the same area is wet and couldn't find where the oil was coming from.
I have the aftermarket oil cooler sandwich adapter, and the bottom side is kind of oily very little but it looks more like a spill from the filter change. And it never gave me a problem before.
Oil Pan Gasket?
After reading other threads, I'm also looking into checking the oil pan gasket (from what I've heard it's not usual to leak there), but it's kind of hard to see.
Rear Crank Seal?
The last time I had the leak on the rear crank seal on the FX16, if I remember correctly, the oil was coming through inbetween the transmission and the engin backing plate, not the engine side of the plate. But the leak I have now seems to spread more than that.
I haven't quite saved enough for the full engine rebuild and hoping to take care of this with minimum expense. Any more input will be appreciated.
