Searching this section but not getting what I want. My case is in two and I'm about to start reconstruction. I've seen Fujibond is used for oil pan, and some spots on the valve covers. I'll see about getting some today. How about between the two crankcase halves?

I've already picked up a couple of versions of Permatex. Black for oil soaked apps. and gray for the warmer sections of the motor. But heck if I wanna take a shortcut on something like this.

So what kinds/brands of silicone sealants should we use and where?

And an aside: Assy lube for the head/case bolt threads to make sure the torque is consistant. Is there a good, Advance Auto purchaseable version?... or something else.

Thanks.

Hondabond. That is the best stuff. I used it on all of my Honda builds as well as my Subaru ones. You can get it from your local Honda or Acura dealer.

Get the Fujibond. You use it on anything you would use permatex on except it is better. Use it on the half shape moons, oil pan, oil pump, ect...

Fujibond, Hondabond, and Yamabond are all company-based silicon sealers, just made/branded for each company, though about the same things. Personally I have only used Hondabond and it has absolutely rocked to no end.

Works like a champ for oil-exposed surfaces. It's cheap,too. :)

-assembly lube I use the redline brand.
-between case halves 3 bond, or Hondabond
-valve covers 3 bond or Hondabond (these are alot similar, honda bond seems to have a better consistancy to work with and sets faster)

With sealants what you want to pay close attention to is
1- to much silicone can spread and clog oil passages (I see this ALOT engines built by others, sometimes so excessive that it has caused the engine to fail)
2- to little you can get leaks (uncomon to see this)

Built 50+ Subaru engines and havent had a problem yet.

Hondabond is expensive. Retail is $24 a tube. The tube is about 1/2 the size of a toothpaste tube. If you get the "shop" discount (just ask, they usually are cool) it's only $12 a tube. 1 tube is enough for an entire build (although I usually buy 2 just in case). I use it for everything: block halves, oil/water pumps, valve covers, cam caps, oil pan, etc.

Either way, it's worth the cost. It's not like you're going to be doing this every week. I've tried to use the permatex stuff (being cheap) but I hated it. It sets much slower than Hondabond and when dry doesn't have the same elasticity and adheasion.

Got hondabond. It's what Flow subaru had (Acura shares the shop.) $11 and change with an account.

How much silicone do you use? The tubes I get are black and are 1.9oz , this tube is alot smaller than the subaru tube of 3bond, but it still will last 4,5,6 engines worth maybe more.
If you can use 1 whole tube on 1 engine, you will have other expenses to worry about than the cost of the tube.

If you have ever used hondabond you will most likely continue using it, it gives you the peace of mind and you know you will have nothing to worry about down the road.

It's the same small, black tube. I think that's the only size they have (unless there is a bucket in the back).

I used a whole tube sometimes because I use it for more than engine sealing; I use it to replace missing timing belt cover gaskets, which in themselves take most of the tube. That's what I mean about Hondabond, it's like Duct tape or JB weld: it has many uses. :P

Whatever you get, please, make sure it is an ANAEROBIC sealant so that you don't get chunks in your oil passage ways, lifters, etc! I've pulled apart too many engines where little chunks of silicone got into an oil passageway and caused trouble.

Silicone sealants should never be used in, around, or near any place where a piece that breaks off could get into your oil-circulation system! It's very risky.

So I could go to the Subaru dealer and ask for Fujibond?
