odd situation with turbo oil return lines at oil pan

[slowguy]

In case I didn't say already, I'm doing a full build with the help of another forum member. I'm hoping for 500 whp.

For the matter at hand. I ordered two orings from ecs using a parts diagram I found on here. I pulled both stainless flexible oil return lines at the oil pan to clean and reseal. On the passenger side line, there is a groove that accepts the new oring (and there was an old oring upon removal). I noticed on the driver side, there was no oring on removal. If I place a new oring on the line, where it looks like it might go, the flange will not seat all the way to the pan. There seems to be no way this will seal properly. Any ideas?

This is with oring in place




What it looks like with it pulled out where I would expect the oring to fit



How it looks after pulled out first time and cleaned with no oring



It seats fully on my daily driver, like I would expect and how it was pulled out of the engine I'm building

Thats a collar that sometimes pulls out. Pop it off the return line and you will see the oring underneath. When i had this happen on a car I had a perpetual leak. Soooo what I did was superclean the area of the upper oil pan. Clean the collar wicked good and then insert it with 2 part epoxy and let it sit over night.

So I can grab a hold of that center piece with pliers and pull it out with some force?

I would be super careful its very thin wall maybe work itup with 2 small screwdrivers

Chisel or something (with very fine edge), try to create a gap between sleeve and flange with it, once you get it moving, keep pushing it out. If you nick/scratch what's on the outside in relation to o-rings, no big deal. Don't grab the sleeve and don't pull from the "inside" of things. You will mangle it and then you will have a real problem.

Use penetrating oil, a little heat if needed. Then epoxy/rtv that piece as advised.

Both of those stupid sleeves came out when I did my build years ago. Perpetual leak, no matter how much black permatex I smear on them. Lucky for my driveway, my Panzer plate catches all the drippings.
