Capping oil drain after removing turbo
 

Hi all,

I am currently parting out my turbo car before getting ready for a move. The motor is drilled and tapped with the barb fitting that comes with FM kits. Has anyone found a sufficient cap to cover the oil drain so I can run the car N/A?

Thanks

If it's -AN, put a -AN cap on it. If it's a barb, I would remove it and use the appropriate NPT plug to plug the pan. I believe FM uses 3/8NPT with their kits, available at any hardware store.

yea it's just a barb fitting as I mentioned. I don't really see myself swapping the oil pan on what will probably end up being a 1200 dollar car. I assume someone has used some sort of rubber cap and hose clamp. I don't see why this would be an issue because the oil drain from the turbo was just a rubber line with hose clamp as well.

Assuming you put the barb in using the FM instructions (standard location at the front of the pan, using a tap and JB weld) you can just put a deep socket over it and turn it out. Then install a plug with some fresh epoxy. No need to remove the pan.

You mean remove the barb fitting from the oil pan? Its JB welded in there. Looks just like this:

My current solution is to tap the fitting and screw in a plug, but i dont really like the idea. I want to find a rubber cap similar to a vacuum cap that I can just hose clamp on. I'm going to message FM and see if they have any part.

Remove the barb and install the appropriate plug

So you asked us, were told what to do multiple times, didn't like the answer because it didn't match what you had already decided, and now you're going to waste FM's time asking the same question?

Cool.

Hit the bung with a socket, remove it, and stick a plug in it. The JB weld might even stay there.

ahh, no I think I was just a little confused and don't have much experience with JB weld. I thought I'd run into issues just trying to spin out a jb welded thread. OK, got it. thanks

JB Weld will give pretty easily if you put down your man's purse while swinging the ratchet.

I make no guarantee that this part is suitable for your application.

I would be concerned that the J-B Weld might fracture and end up inside the oil pan.

Nitrile is the minimum rubber of choice. Also known as Buna-N. Viton is what is needed, but I don't think caps can be found.
