I'm looking for the material that is painted onto the OEM throttlebody plate/bore interface for a better seal. You can kind of see it here (stolen image), but someone seems to have wiped some of it off...oops!



I'm working on something (not a throttle per se) and think this would be perfect. Can someone tell me where to find this or something like it that will work? I tried small amount of blue loctite and it doesn't really seem to do the trick.

 

are you referring to the grey hondabond gasket sealer? if so grab some permatex "ultra grey" from your local auto parts store

 

Oh no no. I mean the dark circle around the perimeter of the throttle plate. That's not just oil residue. Something is painted on at the factory to promote a better seal. I needs me some of that!

 

dumbass thats called a gasket

 

HAHA, READING >>> YOU.

 

im confused, the actually throttle plate doesnt need to seal completely unless the engine is off. if you are talking about sealing the throttle body to the intake manifold, there is a paper gasket

 

I'm not referring to how the throtlebody seals to the manifold, at all. I'm referring to the seal between the throttle plate and the throttle bore. I understand what gaskets, hondabond and rtv are

The throttle plate is supposed to produce a seal when the throttle is closed and the engine is running. The air needed for the engine to idle goes through the idle screw and/or the idle air control valve.

To produce this seal, the interface between the throttle plate and throttle bore is "painted" with a sealant, at the factory. This sealant dries and then the throttle is opened and it cracks the material that was "painted" on, and it produces a perfect break and thus a perfect seal.

I've used my mad paint skillz to show what I'm talking about, since I was apparently not clear.

 

your even dumber thats oil build up from the pcv valve dumb ****

 

I can assure you it is not just oil build up. It may be colored by the oil, but it is a sealant coating on there.

If you can't understand what I'm talking about, then how about you go somewhere else to try and feel better about yourself? Thanks.

Grammar >> Reading >> You

 

Oh no, I feel like a dumber dumbshit dumbass dumb dumb head. I was wrong and was just talking about oil residue. Very expensive and well engineered oil residue

I doubt this is the OEM chemical, but guy in the thread who overbores throttlebodies seems to use it...any (good) thoughts?

 

your still dumb

MOLYKOTE® 321 DRY FILM LUBRICANT

this is lubricant not sealant you even posted it yourself you dumb moron

 

If you're going to continue with the personal attacks, please endeavor to use proper grammar, lest your meaning be misconstrued, my good man.

I think you mean "You're still dumb.", not "Your still dumb." I doubt you're trying to refer to the still dumb of which I am in possession. You seem to be trying to tell me that I am still dumb, which would be "You are still dumb.", or the contraction "You're still dumb." Do you understand?

Another example: "I donkey punch your mom while you're watching scat ****."

Moving on...Please notice the word two before lubricant, in the term "Dry Film Lubricant". That word is dry. How can it be dry and a lubricant?! Ever heard of Teflon? Possibly.

If you bothered to read the data sheet (and have the ability to comprehend it) you would see that it DRIES. It is a DRY lubricant like Teflon. Then, if the next leap of logic is too much, look at the thread I linked to. Someone who overbores throttlebodies has used it on 40-50 throttlebodies with good results, for this same purpose.

Butterfly in the sky. I can go twice as high. Take a look. It's in a book.

 

wanna talk about grammar "lest your meaning be misconstrued"

re-read your own **** dumb ****

 

I'm going to need you to elaborate on this.

 

I'm very interested in finding out more about this coating.
I'm one of the unfortunate, ignorant multitude that cleaned this coating off of the edge of the throttle blade while cleaning the TB, thinking it was merely some of the 215k mile crud accumulation, and now I want to make amends without buying a new TB.

 

I believe the original poster was misinformed. The coating is not a sealant, it is sprayed on TBs from the factory to prevent carbon build up. Its not black, its clear. If you have black build up,its carbon,plain and simple. Eventually the factory coating wears away and then the buildup begins. You will not cause any harm in removing the buildup as the original sealant has already worn away. Ive replaced dozens of TBs with brand new factory TBs and have never seen any with a black coating on them(that I can recall)


(I did read the links he posted,but that is an aftermarket chemical that is not present on factory TBs, despite what he thought. That Molykote seems to be an aftermarket solution for an aftermarket problem)

 

This conversation was an amazing about something so insignificant. Look at every aftermarket throttle body that does not have anything but the clear coating as mentioned above. I'm not trying to be mean or condescending but if anyone would have used a coating on throttle plates it would have been GM the throttle bodies on LS style engines are notorious for carbon build up to the point the vehicle wont run(and Toyota). The reason this generation of Honda doesn't have that issue is because there is an air channel that bypasses the throttle plate for the IAC(because it has a throttle cable and is not electronically controlled) . I would also recommend not using RTV or Honda-bond for installing that paper gasket, something like gasket cinch is much better if you feel the need to use an adhesive for paper gasket on machined surfaces.

 

I know this is an older post but I thought I would reply to help based on some of my findings. This "sealant" or "paint" (whatever it is and whatever the original color is) on the perimeter of the butterfly valve - it is a real thing. Having a TB without it and a car that would not idle properly (purchased this way, someone cleaned it off) and going through every possible solution found on the web, it was eventually found that replacing the TB with a used one that had the ring of "sealant" fixed all issues. Unlike other cars that run fine with a butterfly that does not fully seal it appears that the Honda's (my experience is the H22 engine) the TB must be fully sealed to allow the idle air to be fully controlled by the IACV and the FITV. Well at least it fixed my issues.
Interesting conversation above though, Grammar: "The difference between knowing your crap and knowing you're crap!"
