I am replacing the intake manifold on my 2006 R50. (The old one was removed by someone - long story.) Anyway, it seems there is a rubber gasket that connects to the airbox that the intake manifold that creates a seal between the two. That gasket has basically deteriorated on my air box. It is just a glob of sticky rubber. I have searched for a replacement, but there doesn't now seem to be one. I guess it comes attached to a new airbox, which is quite expensive and I do not need.

Can anyone confirm that the gasket is not available by itself and, if not, any thoughts on an alternative? I was thinking I'd just coat the area with an RTV gasket maker silicon. Would this work?

Here are pictures of the parts in diagram and on I found with the gasket in place.





Thanks!

 

I haven't found a source for that gasket. Best bet is a wrecking yard or possibly someone on this forum who is parting out an R50.

 

It is a pretty gooey mess. I don't know if it would come off of one in a salvage yard. I could probably replace the whole airbox, but don't really want to do that.

 

RTV is flexible. If you don't need that property, perhaps a different type of silicone adhesive would sort this out for you.

If it's unobtanium and it's necessary, epoxy that sucker.

 

The rubber around the hole was flexible at one time. It probably absorbs some of the vibration between the intake and the airbox. If I can't fine some kind of rubber to use, I will use RTV.

Thanks for the replies!!

 

Honestly, it's not even that important of a gasket since it's in pre-filtered location.
If it rattles or really bothers you, take a length of a larger diameter vacuum hose, split it long ways, and make your own gasket. You can use a small amount of silicone to hold that in place if need be.

 

It would rattle around I think if something was not around it. The vacuum hose is a good idea. I was thinking about 4M black Butyl rubber around it, but I am not sure it can stand the heat.
