Case Sealant......Pic
 

Would my case be okay if I used this sealant. I wanted to put the case together this weekend. I got some of this stuff, but I remember reading somewhere to not use silicone based sealants. Is there any other sealant that is recommended, that I can pick up from my local auto parts store?

Thanks,
Rod

Permatex 3H Aviation Sealer would be better. Silicone can have too little wok time and if you don't get the cases buttoned up fast enough, they may leak, or worse, they may not come together all the way leaving your main bearings loose on the crank.

Milt, do they sell 3H Aviation sealer at local auto parts stores, if not where could I get some?

Thanks

What about anerobic from a GM dealer, they use it in transmissions.

Won't dry until the parts are torqued together (might dry too well then though)

Yamabond at the Yami dealer in the morning. It the same stuff as we use Three Bond 1104. Steve

Well , I bought mine at a VW shop. The folks over on Shop Talk Forums like Curil K2. Here's a good trick if you are starting from bare cases. Assemble the cases empty and lightly torque. In a dark room, shine a light in the cases and look for light at the parting line. If all is well, use a very small amount of case sealant on one case half spreading evenly across the whole surface just before setting the other case half in place on your final assembly.

I agree with Zeke, That is what is recommended by all the VW engine builders I have talked to and it is what I used on mine. Works great.

I used to use Curil k-2, But now 1104 is my sealant of choice thanks to Otto who showed me how well it works. Clean all the sealing surfaces with acetone or MEK.Steve

Where can you buy "Top Bond 1104"?????????? Not sure my FLAPS has it.

Ken, you may be talking about "ThreeBond 1104" in a yellow package available at most motorcycle shops.

Steve is this the stuff? Mark

The Yami dealer Yamabond is the same stuff.Steve

Thanks,

Ken

Steve,sorry I took to long to post Thank you Mark

It works great,Mark whats the specs on your 2.5? Steve

Steve it has been about 4 yr since the motor was done. It started as a 1.7l that was made into a 1.9l then a 2.2l est now it is close to 2.5 l in the 1.7 cases. Big crank counter weighted, Big cylinders maybe 103 or 105 big valves. Another engine builder in Orange County helped me and I am Very happy. You also helped me get some parts for the car. I will try to get the specs for you. Sorry I feel silly for not having all of the answers in my head. New baby will do that. I will call you during the week. Have a good weekend Mark

Thanks to all, I picked up a tube of Threebond 1104 from a Harley mechanic this morning.....

Thanks,
Rod

I always had the feeling that the cases should be one piece ... maybe something like this http://www.pauter.com/super_pro.htm .

Now those engines are nice..........$$$$$
