Potential lower or upper oil pan reseal.




I had the rear main sral done less than 20k miles ago.
Oil dip stick tube gasket looks fine(pic below).
I wiped the bottom of the oil pan about a week ago and this much oil acumulated since then which tells me theres no way its the valve cover gaskets.
Im left with the oil pan only. Theres nothing else back there that could leak.
Has anyone done it before? I havent look into it too much? Does the subframe need to come out?
If its the upper gasket, does the engine need to come out?
