I was just under the car and noticed an exhaust clamp that is cracked that i want to replace. To me it looks like the clamp has shifted and is not in the middle of the joint where it should be. At the clamp it loks like there is a crack in the exhaust pipe itself on the bottom. I looked up the parts diagram and there is a sealing ring at that location. Now im wondering if what im looking at it the sealing ring, the mesh part (to me it looks like mesh in the new ring photo). Wondering if the built up material on the exhaust pipe is actually that sealing ring. If so how do i remove it, does that sealing ring compress down and get melted together from the heat forming a seal, can I just knock it away with a chisel, of will it have to be ground away with a grinder? I plan to order a new clamp and new sealing ring. I dont want to start the job without knowing what im in for. Seeing if someone who did this work before can explain what im looking at in the photos.


Parts diagram of the area im looking at. It is the joint with part # 140 and 150. 140 is the clamp, and 150 is the sealing ring.


The sealing ring part 150.


Cracks in the clamp. The clamp does not appear centered to me, looks like it moved left of where it should be. But its not loose, pipe doesnt move.


Close up. Looks like a crack on the pipe on the bottom. Wondering if what im looking at is the mesh part of the sealing ring, around entire pipe, maybe compressed and melted together. Or is that pipe flared out and the pipe im looking at and not the sealing ring?

 

Looking at it from the other side i'm hopeing it is the sealing ring, and not the pipe cracked. And the bolt seems to be missing. This just moved up on my list of things to do.




Edge of sealing ring?


Where did the bolt go?

 

Can I put a new clamp on without removing the pipe, open the clamp up and slide it over then bend it back?

 

First, are you having a problem? Is there an exhaust leak or rattling or anything that is driving your decision? If not, I'd leave it alone until you actually have a problem.

 

Check out clamp I used for same problem area..30,000 miles ago and still leak free. Riker Produc t''Torctite 304SS exhaust 2.5", Part # TTS250" (tried to download photo but "no go". Had to wire wheel off the crud and smooth down surface.

Thanks for the tip..

 

With the car running and looking underneath I dont hear a noticable exhaust leak, sounds normal to me. But when i'm driving with the passenger window down I can hear a ticking sound when accelerating. On a cold start the passenger side manifold area is really loud, not sure if the gasket is bad or it has to due with the secondary air doing its thing. Also besides the clamp in the photos above the same looking clamp further down on the drivers side is cracked the same way, so I do want to replace the clamps fearing it failing while driving then ill be really screwed.

Id rather fix things now with the nice weather, than wait for something to break or fall off and its the middle of winter. I have quite a list of things to address. Oil filter housing and oil cooler gaskets, replace coolant, oil drip pan, breather cover, oil separator, secondary air valve gaskets, trans fluid and rusty trans pan, now the exhaust, spark plugs, rear control arm bushings. I enjoy working on the car.

 

Excellent point!

Sounds like you're going to be a happy guy!

 

Just received the sealing ring part# 2044920081. Very strange looking, though i never work on exhausts so this could be common. One side is exposed wire mesh, the other side came with a cardboard protective ring on it. Take it off and that side is a smaller diameter. Im assuming it can only be fitted one way, one side going into the pipe and the mesh side going over the other pipe. I want to say its made out of lead, its heavy and soft metal. Wondering if thats how it works, it melts to form the seal. Still waiting for the clamps from another store in the mean time. I'm hoping the old one comes off easy,

 

Just picked up some exhaust weld to hopefully repair an exhaust issue. When i removed the old clamp i noticed some of the pipe itself was brittle and broken off. The sealing ring seemed fine so left it alone. I just removed the old clamp and fit the new one on.













I was at the auto store and saw this product. My plan is to smear it on and form it nicely so the clamp will fit back on. I chose this because it says it cures like a weld, as opposed to the JB weld exhaust that says it cures like a cement. i want to seal it up so hot gasses arent flowing through and giving me an issue with the new clamp. The old clamp looked like it cracked, maybe from the heat?

 

Finally nice enough weather to work on the car. Removed the clamp so I can smear some of that exhaust weld on and allow it to cure overnight. Nothing major, just want to try and make sure no exhaust gasses blow out where they shouldn't be and also build up the area where the pipe was cracked off and missing so i can tighten the clamp all the way. Product is very easy to work with. Wire brush the area to remove any loose stuff and rust, cleaned the area with brake cleaner, wiped area with a wet rag per instructions then spread on with a craft stick, smoothed with gloved fingers. Theres another clamp down near the drivers muffler that is also cracked/split that I need to replace. Its odd how I have 2 clamps that have cracked/split apart.

 

Did this fix your noise issues when driving? I have a C250 that seems to have similar issue to yours.

 

I dont think it was leaking to begin with, I just replaced the clamps because they were broken. The clamps are holding up fine.

 

So do you still have this issue?:
"But when i'm driving with the passenger window down I can hear a ticking sound when accelerating"
I have a similar issue to that.

 

Oh, the ticking. I really dont know what it is, i thought maybe it was a hole in the passenger exhaust manifold. I keep forgetting about it since I hardly hear it.
