Topic: Hondabond differences

[Davidov]

I have Loctite brand "Gray RTV silicone" which shows to be an OEM equivalent to Hondabond, but only Hondabond HT. It does not mention Hondabond 4.

Same with Permatex brand "gray sealant"

Then there's this Acura service bulletin
http://www.acuralegendwiki.org/images/d/d6/AcuraServiceNews_1998-03.pdf
It states to not use Hondabond 4 on gasketless surfaces...but HondaMan uses Honda/Yama bond 4 in his book.

I say the Loctite version is just fine.
Clear as mud right? Did I just start a dreaded "oil thread"?

I'd stay away from the RTV sealants.  Flaking off and clogging oil jets would be a worry to me.   
Threebond 1184 has been used by many here with success.  I used it last time I sealed cases, and I will use it again. 
Light gray matches OEM case color.

Yeah.. worms.  I think my threebond is yellow though?  Now I'll have to look when I get home...

I  heard that the suzuki 1207B is better from all the honda mechanics that I've met.

Why not just get Hondabond and save the worry for something else? Not trying to be condescending at all. I was in the same debate and I just spent the extra.

[Davidov]

I'm going with Threebond.

The data sheet for Hondabond calls the chemincal oxy-something-something, where the Permatex/Loctite is still a silicone product.
It's really a substitute, not a direct replacement for Yama/Honda/Suzu/Three bond.

[bjbuchanan]

You can also use permatex non hardening sealant, available at almost all auto parts stores, easier to source. It is non hardening like yama, hondabond, threebond. Only difference is that the permatex seems to set just a little faster.

Not a big deal if you apply it when you are actually ready to put the stuff together. I used it on my cases and cam tower pucks with good results. It is recommended in Hondaman/Mark Paris book as a substitute if that helps too

Do not use RTV Silicone!


The original gasket sealer used at almost every motorcycle shop was Gaskacinch and is still available.

Yamabond and Hondabond are copies of Gaskacinch. EXACTLY

When I see any color of RTV Silicone on a motorcycle engine I know a beginner was working on it. I immediately have to investigate and clean that stuff off so it does not get loose inside the engine and plug up an oil gallery.

Honda cars and Honda motorcycles are apples and oranges.
I was a Dealership Honda motorcycle mechanic and there was no OEM gasket sealer.
All the shops used Gaskacinch.


On the engine cases just apply to each engine case half,
when dry, assemble the cases.

I used Threebond 1104 on my first rebuilts. It worked perfectly, no worms, good adherence to the crankcases, perfect sealing on no gasket surfaces, no oil leaks. When I finished the tube, I couldn't find 1104 any more. I bought Threebond 1104 NEO, not the same stuff, it doesn't adhere to the surfaces the same way, is more liquid and you have to wait too much for it to dry.

1104 was replaced by 1184, IIRC.
sets up in 15 min or so....

I'm interested in this exact question. I intend to stay far away from any silicon / RTV-type product--I've cleaned enough of it out of my engine already... I'd also like something non-hardening.

Dino (of Hackaweek fame) swears by Permatex Aviation Form-A-Gasket. Permatex claims it's non-hardening.

Others go with Permatex Ultra Gray, but that's silicon / RTV... So is the Suzuki 1207b mentioned above.

Gasgacinch sounds deadly (see their MSDS)...

I'm a bit surprised to find that Hondabond 4 and HT are both silicon based. Can anyone confirm that? Is there a different kind of Hondabond that isn't?

[PeWe]

Hondabond worked well for the cases. But it was really sticky to apply. Thinner than I thought easy to make a mess with it.
Not hondabond for gaskets when it glues the gasket very hard. I had on my valve cover gasket and have to spend 1-2 hours to remove it from the head when lifting head cover and gasket broken. I used it on one side only.

I'm curious to try Gasgacinch if it is a non hardening stuff to use on the rubber pucks under the cam tower and on the crank oil sealer behind the points plate and outgoing axis (front sprocket)
