Exhaust Burning Through Clam

[Ladders]

Had thought I'd managed to adjust the exhuast (after bending the hanger this way and that for 3 hours ) so it didnt burn into the clam, again!

 

But noticed it's started to do it again, even though the pipes sit in the middle of the hole

 

So was wondering, would it be a good idea to rivet a some sort of stainless steel at the top of the hole to protect the bodywork?

 

Cheers for any advice!

Bit surprised at this, Dave.

 

Ordinarilly, if it's not touching, it's hard to imagine enough heat getting to the clam to burn it.

 

I know the chav brigade staple metal plates above their exhausts - please don't tell me you're serious about that option !!!

 

A metal plate only works if it's held away from the material it's supposed to be protecting, giving some reflection of heat and hopefully acting as an insulator by keeping a layer of air in between as well. If it's in contact, the heat will go through it almost as if it's not there. After all, you're replacing a (eg) 2mm think piece of air (with low heat transfer) with a 2mm piece of metal (with some reflection of heat but far better heat transfer than air). Overall effect will be negligible at best.

 

The other reason chavs use them is that their engines are so knackered that they burn loads of oil and discolour the plastic around the exhaust. With a metal plate, they can take a brillo pad to it and not damage their lovely paint jobs.

 

I'd get the fundamental cause investigated rather than trying to stop the effect it's having.

someone at mallory had one of them. As they are metal - do they not attract heat and warm up more than the plastic would anyway ?

 

ive also got a prob with my exhaust. One of the hanging down brackets on the drivers side is rubbing against what its hanging on and squeaking. rubbed it with grease but it keeps wearing off. Doing my nut in squeaking.

Honestly, if you could actually attract heat, you'd be the richest man on earth (even richer than Bill Gates). You could harvest all that energy and solve all the world's energy problems in one easy step.

 

In reality, metal just keeps heat longer than air or clamshells, so it feels warmer for longer once heated up.

I think my exhuast must swing up when you rev the engine or something?

 

I was thinking of sticking the metal on so the exhaust hit that instead of the clam!

Mike gave me some metal effect tape to put around the exhaust area on mine as this was happening.. really should get round to it.

 

Looks a bit like duct tape, he seemed to think it would do the trick.

[Ladders]

I've got some aliminium tape, but thought it would probably just melt through that as well?

[Scott_Mac]

Doubt it... thats probably what i have....

Fwiw,

I had a similar problem with my S1,don't know what zorst it was but in the end the only solution was to use some Ali sheet to protect the clam.I understand what Chris is saying but the zorst was just burning the paint so it did the trick so to speak!

If you need some ali sheet let me know its about a mm thick and can easily be cut to size.

Has anyone removed the metal plate afterwards ? Could be that the clam or paint is still being damaged, you just can't see it ?

[Ladders]

Thanks for the offer Jon!

 

Doing a few bits on it this afternoon so will see what the best thing to do is?

 

Might just need the exhaust fettling again?

[dobbo]

Ladders, are the exhaust mounts knackered ? That might explain some of the movement.

I think because you use Aluminium it reflects heat well and dissipates any it has absorbed quickly.

Well done Chris, you guessed the right answer!

 

Had to do an oil change and replace the cat, and one of the hangers had gone!

 

Put some ali tape at the top of the hole to hopefully protect the body untill I get it sorted .
