so i have an o-ring that looks like this (http://6ixx.net/itb/DSC_0851.jpg), off one of the runners on a set of itb's

failing to find a directly replacement, can anyone recommend any liquid gasket stuff that will hold up as well as an o-ring?
i looked at what i had and found some loctite rtv blue but it says on the tube not to use where it will be immersed in fuel :(
went into a few stores and came out none the wiser

I heart the SSS

Go to a bearing shop. They have heaps of o-rings in weird sizes. This is the one I use to get odd-size o-rings is Advanced Bearing on Unit 1, 2 Forge Street in Blacktown. Here is their website: : http://www.advancebearings.com.au

Bring your ITB runner in with you so that they can find the correct size.

we would have this size at work as we have hundreds of different sizes

No problem. Hopefully a.b.c bearings has what you need. Otherwise, make a trip out to Blacktown.

in the mean time, time to rip them apart for the second time to clean off all the sealant and clean it :(

so as it turns out, a.b.c. bearings are long gone from south street in rydalmere(which is literally down the road where i work)

gonna hit up a couple more places on silverwater road tomorrow morning and see whether i have any luck

on another note though, between the throttle body and the adapter that bolts up to the block there is a metal gasket which is dry at the moment i.e. all metal contact
should i smear on a bit of rubber grease for good measure?
after seeing the o-ring i'm not too trusting of just the metal plate alone anymore..

Don't use rubber grease. Use gasket sealant like Permatex Ultra Blue. Hondabond is a bit strong and could ruin the gasket when you try to remove it the next time.

wouldn't that stuff just be eaten away by the fuel?

Oh shit, you're right. Choose one that doesn't get eaten away by fuel.

Or test with just the metal gasket first to see if you have any vacuum leaks. If there are none, then don't use sealant.

yeah i just put on a thin amount of grease and put it back together
gonna assemble the rest of it with the new o-rings later today then figure out what i want to do about filtration, such a pain

dug around the sealant section, appears nothing likes to be immersed in fuel so hopefully the grease will seal it enough + the metal gasket

remember kids, with enough lubrication we can do anything ;)

yeah i heard sock's were bad for itb's though so at the moment they're sorta last resort next to running them open + mesh sheild
