I picked up a 2006 4 banger 2.4 TJ project to work on with my 14 year old son. Today I finally dropped the transmission to replace the clutch and dropped the oil pan too as it is dented and leaking. Glad I did, as I found a loose bolt in the oil pan and a bunch of RTV junk in the oil uptake. While looking around I also found a strange hole in this part (maybe oil pump )that sits above the oil uptake. Anyone know if this hole in the picture is normal?
