Case Sealant
I promise I am not rehashing an age old debate here but…
I'm a 574 fan, but lately the case sealing surfaces are looking worse and worse. Even Ollie's is putting a relatively rough cut when they align bore. So… I have been using DOW730 with great success (it's much more expensive though). Today I was reading the factory manual for the 996tt (Mezger case) and it says to use DreiBond 1209. This makes me wonder if the 1209 (which is easier to source) would be a welcome case sealant for the older cases also. Has anyone used 1209 on a pre-wasser cooled motor as case sealant with success?

If you need fill, I like Yamabond, Hondabond, three bond. Got to apply to both surfaces.as directions.

Permatex Ultra Blue, applied sparingly, works well when you have rough surfaces. Cheap and easy to find.

So I guess this means no one has tried 1209?
The water cooled stuff has some pretty rough surfaces for the valve covers and sump plates. It would be nice to minimize the number of chemicals I have to keep on hand. Haha |

Hondabond 4, and Yamabond 4 are both rebranded threebond. I went to the local Honda motorcycle dealer and bought a tube for 6 bucks. It looks like this: Dirt Bike Pro Honda Hondabond 4 | MotoSport
I used it on the cam tower to head surface and on the chain case to engine case surfaces with no gaskets because the heads had been milled down around 018" and going gasketless on the chain cases made them line up with the cams just right. The motor has no oil leaks or oil sweating anywhere. It's nice stuff and cleans up easily with laquer thinner on a rag. |
