Doughnut gasket help!

Featured Replies

I've never used these types of gaskets before the donut type which is between the output of the 2nd cat and center pipe on my 95 Legacy L which way should the gasket face in the center pipe?

Ok looking at it more it must be picture one but it looks like I'd need to clean the inside of the flange so it would make a good seal.. I don't have a wire wheel.. is using a light grit sandpaper ok?

Yes, you can sand, scrape... to get the flange clean. You have it on right, you will see the taper on the aft exhaust pipe once its clean.

thanks so I will sand the inside so its smooth not sure how this exhaust is going to sound over my stock 95 I got a used bosal/subaru 2.5 gt muffler along with the center pipe

the people who did my work on my car they wielded the spring bolt, bolt to the nut I would guess no way I can save it?

 

If not can I just replace it with a normal bolt and nut?

I installed everything with the gasket part number 44011AC000 for my Legacy I start the car and I have a leak in that area and I saw the doughnut gasket just spinning around with the car idling.. I don't know how much tighter I can make the center pipe...

 

Do they have something else you can use besides a doughnut gasket?

if you bolted it together and it still leaked, i don't really know. but i have read post where people have just used regular bolts and tightened it up.

 

when i did my ej22 swap, i could not get the second bolt threads to grab, so i bought a longer bolt with out the 'special' shoulder and bolted it up using an extra nut and washer and the original spring to re-create the intended design.

 

the springs are intended to create a flexible seal??????

I don't know I put the gasket in the center pipe like in the first picture so the tapered smaller end was in the pipe but the gasket just turns.. and drips a little moisture as well.

 

To me, the first photo is the wrong way and the second the correct. Flop the gasket and see how it works.

I turned it around and it still leaks!

 

do I need to sand more? I'm running out of time today

turns out it smaller I don't know how and I don't know if the part number changed over the years.. this exhaust comes from a 2.5GT model legacy wagon..

 

The last issue I have now is (maybe because I don't have spring bolts in right now.. can't find washers large enough) Is the center pipe to the muffler area with the gasket it's got a small leak. I might be able to work it out by giving a little slack but it's hopeful.

The doughnut gasket paired with spring bolts is intended to provide a joint that's flexible. I think also, it provides an emergency outlet if anything ever becomes clogged in the system.

 

I just assembled one of these joints and didn't have any issues. Doughnut goes in the direction so the curved surface mates with the curved flange. I believe this would be your photo 1. To install, you need to slip the doughnut over the PIPE and it should be fairly snug. If you sanded the outside of the pipe down too much so it's loose that could be your problem. You then tighten up the bolts. I would not run this without the springs. They're not that difficult to get.

I still have the springs I just need new bolts because I snapped one of them in half.

If that's the case then all you need to do is measure how deep the old bolt would have driven into the nut so you get the correct spring compression. Use the new bolt with a nut and jamb nut and it should be good.
