oil leak from side of block

Hey guys, new to the forum and I'm desperate for answers. My 07 jk shelled the engine @ 60k miles. I replaced it with a new long block and now this engine appears to be leaking from an unthreaded hole on the driver side of the engine where the motor mounts bolt to the motor. I'm not getting help anywhere. Its the damndest thing I've ever seen, I want to love my jeep but beyond frustrated, can anybody point me in the right direction?

I looked at my 2010. It has the same kind if hole, directly below a plugged hole. I was hoping I could tell you there should be a plug there, but I didn't see one on mine.

Wish I could've more help....

Is it actually dripping oil? Or is a small amount of liquefied junk kicked up from driving collecting in there and over time it appears to be leaking? Just a thought............ I'd spray some brake clean in there and clean it up let it sit w/o driving it, and have a look again. It could also be weeping oil from a poorly cast block. Cleaning it would help in making that determination.

Yea I witnessed oil pouring out like a drain plug was removed but best I can tell nothing is supposed to plug that hole. I cleaned with brake cleaner and tightened the threaded plug above it and it seeps out now at a drip which has me more stumped. I found a thread on the forum previously someone had experienced the same issue but never reported on what fixed the issue. I'm clueless.....

Since tightening the plug above slowed the leak, I would try draining the oil, removing the plug, clean everything, and install the plug with some good thread sealant. It sounds like the two holes communicate or drips from the plug are accumulating on the hole.

Still leaks, really bad if put into gear. I have up and took it to the dealership. I'll post what it was when and if it gets fixed.

Hate to hear the problem isn't solved yet. Hope it is a cheap fix.
