open it and squeeze some out , it seems to be that it is SUPPOSED to be less consistent than tooth paste.. check it and see..

I just ordered a tube of yamabond4. Should be here Friday so I can continue the build. Not worth messing around with such a critical area.

JonT 03-31-2016 05:23 AM
so which Threebond is the Yamabond rebranded? 1104?

theiceman 03-31-2016 10:29 AM
yes I think so from what I read here.

We looked at it on line in the Yamaha dealership and it described it has non hardening flange sealant. I new right away that was the one I wanted as that is how they describe the Loctite.

for 20 bucks CAD for such a critical piece I thought it a drop in the perverbial bucket.

Pelican sell a complete sealant kit with everything you need.
You can also buy ThreeBond and all the other proper sealants (including Dow 55) from 911 Vintage Parts.

Don't do Yamabond 5, I did, and fully regret it.

5 is watery and too thin.

theiceman 04-01-2016 04:12 AM

I will in terms future, but not just because that.

I think I have some broken rings from an ego race in 100°+ weather with too much timing against a guy and his buddy on an M3. Kid wouldn't stop pestering me race after race. I guess he liked getting smashed in every race?! Ha.

Oh yeah, I beat the M3, the Porsche gods beat me! :)

Does the yamabond have to be applied to each surface? How much working time do you have with it?

picinkoff 04-14-2016 03:10 PM
Question: To which (paper) gaskets do you apply 574?

As posted by CBRacerX, ThreeBond sealants are recommended for the following components, all of which use (paper) gaskets. ??? Are there other gaskets I'm forgetting about?

1) Intermediate Shaft Cover to Case: ThreeBond 1211 (now 1215)
2) Oil Breather Cover to Case: ThreeBond 1211 (now 1215)
3) Cam Chain Housings to Case: Threebond 1104 (now 1184)
4) Cam Chain Housings to Cam Towers: Threebond 1104 (now 1184)
5) Cam Chain Housing Cover to Cam Chain Housing: Threebond 1104 (now 1184)

Again, thanks for your help and good humor!!!

I only put it on the cam housings then dropped the heads on . I am not sure what the working time is but I had the heads on in about 2-3 minutes then flipped the whole thing over and started torqueing them down , all together about 10 minutes , I think working time has to be at least an hour as I came back two hours later and it was still very tacky . Il see if the tube has more info.

the only one I am wondering about myself is the cam chain housing cover.

When I took my car apart the previous person only put sealant between the gasket and the housing , but nothing between the cover and the gasket.

There were absolutely no leaks and I was able to pop the cover off just from undoing the nuts with no issues. It worked fantastic

I m not sure but I think this may have been intentional as this is to me a " service cover" to do cam timing, check/ change tensioners. I think it would be miserable to try and do any of that with the engine in the car if this cover were " glued" on and trying to clean the surface of the housing afterwards while in the car .

Just a thought.

Outer case halves perimeter : Threebond 1104

Bearing web surfaces: Loctite 574

#8 Bearing O-Ring: Threebond 1211

Case Thru Bolts: Dow Corning 55 on Green Viton O-Rings

Flywheel Seal: dry

Front pulley Seal: dry

Intermediate Shaft Cover to Case: o-ring Dow 55, gasket style 574

Oil Breather Cover to Case: Loctite 574

Cylinders to Case: Curil T

Cam Towers to Cylinder Heads: Threebond 1104

Cam Chain Housings to Case: gaskets Loctite 574

Cam Chain Housings to Cam Towers: gasket Loctite 574

Cam Chain Housing Cover to Cam Chain Housing: Gasket Loctite574

Gaskets: Thin coat of Loctite 574

The Loctite Hysol is a perfect epoxy for sealing galley plugs and tensioner pins.
On late 3.0 & 3.2 cases it also seals the exposed oil tranfer tube in front of the cooler.

If you can't find 1104 use 1194 and Dow 55 can be replaced with 111
