After pressure testing my intake system, I found a leak at the bottom of my throttle body. I’ve read as much as I can find on what to do next, including rebuilding it, but I can’t find any kits available. Arnnworx is down and Paragon is out of stock.

Should I just buy 3 O-rings or do I need to buy other parts? What about upgrading to a larger one? Any help and recommendations are appreciated.

TIA

Try to source o-rings and if needed, the needle bearings. There is little point fitting a larger one if you are running stock size valves.

I'm pretty sure I have an old kit. Let me see how much of it I can replicate. The key parts are the o-rings for the throttle shaft, and I'm sure McMaster has those.

I have seen several sites that have the O-rings, FCP Euro and Pelican has them as well.
Tom, let me know what you have and I’ll make the trip up there to get it.

Thanks Thom and Tom.

Never mind my bellow comment.
I will have to post pics when I get home. I thought I posted all my throttle body rebuild pics.


If you have not seen my posts I have a bunch of stock throttle body pics on here.

I will dig around

Also I can measure my oring kit when I get home

You can buy bags of those orings for cheap from The oring store or mcmaster

If you can find a can of this No Flash contact cleaner it’s the best thing I have ever used to clean out a throttlebody.

Blasted the bearings spotless and that was looking through a magnification scope at my work.

Thanks Gruhsy!

My bad

I got distracted working on my motorcycle last night.
Will try to remember when I get home today.

I have 3 throttlebody’s apart and a 4th from Soloracer’s car ready to come apart.

So correct me if I’m wrong here, I will need 1 large O-ring, 2 small O-rings, no flash contact cleaner, and 2 small circlips?
