So I just went out to explore what appears to be a new oil leak in the underneath of my FJ40. As I am tracing things back, I decided to check the oil pan screw/bolts, and I realized they are all loose. I mean, like they aren't even finger tight! Now, I haven't messed down there in a year, since when I first put it on, so I don't understand why things would loosen up. The drips just showed up 2 nights ago. No screws are missing, but they seemed loose enough that it wouldn't surprise me. Anyone run into this before? The gasket is OEM and cork, so I was wondering if it somehow shrank with freeze/thaw conditions. Seems weird.
