304 oil pan

[mbrunelli]

Hello, I am new to the site. I am an amateur mechanic and will be reading here often! My v345 in my 79
scout II is locked. Just sourced a 304 which spins. Moving it around I noticed it is puking oil from the side of the oil pan. At first I thought it was a catastrophic failure but I believe the opening is supposed to be there. I have looked up threads and images but cannot find the name of this part/plug or understand the purpose of a second opening in the oil pan. Thanks for any advice on problem number 1!

if it's a two sump oil pan, the whole in the side is for a dipstick. The trucks had single sump oil pans with dipsticks in the front of the engine.

Note, you can switch pan/pump/oil pickup between engines, but need to make sure you bring the special stud and nut from the scout eninge to the new engine.

Thanks Derek
If the opening is bare on the outside, Is it likely the inside half or component has fallen into the pan? Wondering if I need to take off the oil pan to check or replace or to reinstall a new one?

Hi,

I’m not sure if there is a piece that would have Fallon in, my dipstick is just caulked in. I would cover that hole to keep oil in and dirt and water out. Or add a scout two dipstick to fill the hole

Surely if it looks like it was created by the factory, perfectly shaped hole, You wouldn't ne discussing something grenading, but I'm thinkin' maybe the hole for the dipstick?

I have a truck pan that is single sump, with the dipstick tube grommet on the side as well. It was what I was going to use for a 10qt pan, rather than cutting the center hump out of a Scout II pan, but soon after discovered the Scouts had their own Oil Pump.

What You're saying must apply to older vehicles, when they first had the filler tube in the timing cover or sumpin(?).

This is the hole. If it is for a dipstick, I cannot find a part number or one that I can purchase online. When I look up images, I don’t see an image like this on Google.

100% the dipstick hole. Scout oil pan. Check lightline dealers.

Or make one out of 3/8" tube.
