That orange crap is the most awful looking product you could use for this job.  It "screams" I have been inside this engine and put it back together using the most obnoxious product I could find.

And as DragBikeMike stated in post #8.....you put sealer on the sides of the little oil reservoir along the cam....it should not be there.  Look at the head cover, and if there is not a matching surface on the top for the sealer to squeeze between - don't put sealer there.

For silver colored engines it look far more professional if you use a gray sealer......like Yamabond.  For black engines use a black sealer like Suzukibond - both of which are actually made for sealing motorcycle engines.

I put a very small amount - just a tiny thin smear.

Thanks, Gentlemen.

Is Yamabond a discontinued product? The amazon-page says: "Currently unavailable.
We don't know when or if this item will be back in stock" and I am not sure it is possible to get it in Sweden.

I use what I can source here so red silicone motor gasket is in my opinion better than none at all.

Today I fiddled around with a pneumatic dispenser I bought of ebay. I wanted to see if it was usable to dispense gasket silicone and it actually was. I had great fun and learned something in the process

I use an arduino to controll a pneumatic valve that pushes the gasket silicone out of the syringe. The first test I just let the arduino to open and close with a set time, but once I got that to work I used a couple of pieces of copper tape so I could manually activate the dispensing system with the tip of my finger

That sure does look like a marvelous way to apply sealant.

I'd be willing to bet it would be perfect for our head cover. No seeping out and perfectly distributed

Yep - Cool!

I use plastic syringes with a plunger I have to squeeze manually.

I put down a bead just a bit smaller than a pencil lead.  You want enough sealer so that a tiny bit squeezes out both sides  and provides even coverage across the mating surface.  The sealer that oozes out doesn't do any actual sealing - it is more of a telltale that you have used an adequate amount of sealant.

I found that the sealant doesn't stick to the smooth plastic of the syringe - so after about a week you pull on the plunger and the PVC pops right out of the syringe!
