Vacuum Leak

Can a small vacuum leak be plugged or do I have to replace the whole line?

Where is the leak?
Always better to replace the line...vac hose is cheap. A few bux can replace several feet of hose.
If the leak is in a canister that costs >100bux, it's worth trying to patch.

I'm not sure where the leak is yet. I got my oil changed (I know I could have changed the oil myself but it's to hot) today they said I have a vacuum leak that I need to plug. I finally had a minute to go look for the leak but it's to dark to see where it might be coming from.

Starter fluid while the engine's running will help you find the source. Spray it along the line, and if you hear the engine pick up, you've found the spot. I wonder why they said you have a leak. Did they explain it? Wait, I'm giving you advice. I can't imagine it's something you don't know, but on the off chance.

I know. You should just trade Jeeps with me. I've had my vacuum issues resolved so all's good there. Good. Now to meet up and complete the transfer. *Rubs paws together.*

I can definitely here the leak I just don't know exactly where it's coming from yet. I kind of have a general idea but I'll have to investigate more tomorrow when I can see what I'm doing.

Haha there is so much stuff I still have to learn, mostly engine stuff because I haven't spent much time working on them. That's the point of these forums though, most everyone has knowledge about a certain part of the jeep, we all work together to get the problem fixed. One big happy family. (maybe not that happy lol)

Oh and no thank you.

I found where the leak is coming from.

This first picture is just for reference.


Here is where the leak is.

is that the hose that goes from the master? I think that would be pretty easy to replace, it looks like it would just pull off the fitting at both ends.

I don't think it's a hose. It looks like it's just a plug that goes over that small tube.

Yep that's exactly what it is.

From looking at mine, I didnt want to rip it out, I think you could get away with RTV for the time being. It seems like there is a little nipple that is flared on the end that holds it in place. Might be a dealer specialty part.

I don't know if I would put rtv there to potentially get suck in. It doesn't look like a very unique piece though. I'm sure you could find a plug somewhere. Even a tapered plug with a head maybe?

I grabbed a pair of needle nose plyers and got it to come off. It looks like a little rubber end cap. I wonder if autozone would supply it.

When you find them, pick up a bunch of them. If that cap is shot, you can bet others of the same vintage are not far behind.
