2001 Nissan Pathfinder Oil leak help

[nicolelynne0391]

I have a 2001 Nissan Pathfinder 3.5l manual transmission and I just started leaking oil and I found where it's leaking from but I don't know what it is any help would be great Thank you
The pictures are if I'm under the passenger side looking towards the front of my truck and the the leak is from the thing in the green circle and I can move it if I touch it

It looks like some random plastic plug or some sort that was stuffed into the weep hole space to keep a seal leak from being noticed when it would normally just dip out the weep hole. Take the plug out. If the bell housing gets enough oil puddled inside the bottom of it, the flywheel is going to sling it all over the insides and likely saturate your clutch friction disk and cause it to start slipping. The weep hole ensures the build up of leaking oil within the bell housing does not happen and it gives you a heads up, when you notice oil dripping out of it, that you have a seal leak from the rear or the crankshaft or the front of the transmission, depending on what type of oil is dripping.

And I might add, the 3.5 seems to be prone to rear main seal leaks. I know mine does, although only if I park it uphill. Flat or down it doesn't leak due to how the oil level shifts, nor does it seem to while driving. Search a bit, it seems to be common, expensive to fix if you don't do it yourself, and often replacements themselves leak. I've got a rag velcro'd below mine to keep it from dripping. I call it a diaper.
