3-bond vs. Permatex
3-bond vs. Permatex
(OP)
I've got an oil leak where my valve cover of my motorcycle engine bolts onto the head. The local bike shop says they use 3-bond 1104 gasket sealer but all I can find is Permatex.
I understand that they are both silicone gasket sealers that do not harden and are meant for high temperature engine applications.
I've never used either before and was wondering if anyone has used the Permatex brand. Also do you need special gasket remover to clean the old gasket, I've been reading that brake cleaner or paint thinner can be used to remove the old material.
Are there any tricks to using either of these products?

I ended up using the Permatex Ultra Bond over the weekend. Everything seemed to go fine and I'll have to wait till I run the engine to see if the repair was successful.

I used the old "YamaBond" on bikes years ago and TB 1104 is, apparently the same stuff. Obviously, I'm sold on it.

RE: 3-bond vs. Permatex
I was calling around and could not find the TB 1104 or I sure would have used it. I don't think that the valve cover sees a lot of pressure as there is a breather hose attached.
This actually leads to another question, for which I should probably start another thread, but here goes.
I have a breather from the engine crank housing. It's routed through the frame of my bike and them out to the air box via another nipple on the frame. I'd like to move the hose off the frame nipple to allow access to the carb (adj. of the fuel/air mixture screw) while the bike is running.
Is there any reason that I should be concerned about unplugging the breather from the frame temporarily while I make the adjustment.
