Dumbo question approaching - exhaust gaskets
« on: July 08, 2007, 12:21:41 PM »
Forgive me, but my only experience has been with dismantling my 650Z, so when new parts arrive in the post they don't necessarily look anything like the bit I took off due to PO's changing bits, or puttting things together wrong, or whatever. OK excuses over.

In my gasket set there are 4 rings that look like a felt or wadding material wrapped with a gold wire. Now they are (obviously?) exhaust gaskets. Question is, there was nothing like these that came out when I removed the old exhaust, just a copper ring (in fact 2 copper rings on some ports!!!)

I like the look of these felt gaskets, but is that all I need? Or do you use copper ones? As well, or instead?

Sorry, might seem a dumb question, but I can only go by what came off when I pulled it apart. And it weren't these little babies.

thanks for your help, Phil

There is an amazing variety of exhaust gasket types. The original ones had an asbestos core I think and, asbestos being a hazardous material now, they aren't made that way any more. If the ones you have fit in the ports OK then use them, I've had obviously wrong sized ones come with gasket kits. Make sure you get all the old ones out - it is not unusual to find more than 2 in a port.

And what you describe as "felt" probably is asbestos.  An old gasket kit on the shelf is probably the reason.

Sometimes the oem gaskets are so sooty and squished you can't see them in the head. A skinny screwdriver carefuly punches them out of that black hole.

Are the gaskets black? Some manufacturers are using felt like carbon fiber gasket material. I believe the advantage is that they withstand heat better and don't shrink.

Here's one of 'em...

Looks more like a c&%k ring than a gasket if you ask me ;D

An asbestos c&%k ring! Now that's some quality S&M. :D

I'll bet those are old asbestos exhaust gaskets. Wear gloves and a respirator when installing them!

That is the same exhaust gaskets that came in the stock Honda gasket set I bought for the 650 from David Silver, and they do work as long as you have removed the old gaskets. You can skip them and buy copper gaskets instead. I think the 44mm copper gaskets will fit.

that exhaust looks loud, how would you tell if it was leaking? The diameter is bigger than the intake!

haha, no offence, but are you kidding? a hazmat setup for four rings? :D
asbestos is most dangerous when in very fine particulate form that can enter and deposit in your lungs.
otherwise, these rings are "mostly harmless" unless you live in California, where everything is cancerous or dangerous.
