oil pan appendage
Pulled out this oil pan to use in my new build and noticed this.
Thought it was a return line from an added filter,but upon inspection I found it is blind with no opening on the inside of the pan. Any idea what it is for ??? |

Re: oil pan appendage
Look on that blind spot on the bottom side and see if there is not a slot cut in it to direct oil flow towards the bottom of the pan.Spray some carb cleaner or WD-40 in the fitting and see if it comes through to the inside.

Re: oil pan appendage
The return hole is located on the bottom of the appendage.

Re: oil pan appendage
If it has no return hole, it may be a plug for a vehicle with no filter added. (return delete)

Re: oil pan appendage
As has been indicated there should be a slot in the bottom which directs the oil flow toward the bottom of the oil pan.

Checked and found a small hole about 1/16 on the bottom.

Re: oil pan appendage
1941 pans had a return fitting at that exact spot. I've had pans like yours and have wondered, like you, why the "patch" on the inside.
