A small screwdriver is used to insure that the circlip is fully seated.
Next, loctite is applied to the plug that covers the installation port.
The port is closed with the plug. This process is repeated for all 4 pistons and the short block is now together.
The bottom end of the engine is just about together.
Copper wire is cut to length to form the gasket o-ring. First, one end of the wire is filed flat.
The wire is carefully tapped into the receiver groove on top of the block deck.

Fantastic series Mike. Seeing this level of detail is masterful.
Is the situation with assembly of the piston pins the same for 6-cylinder boxer engines? I can’t imagine how you would get the pin into the center cylinders.
Also, there must be an obvious reason why the block can’t be assembled with the pistons, but I am kinda spacing it. For the Boxer builders, how does ease of assembly compare to straight engines?
Now, I am really curious as to how Porsche assembled their flat-12s. Going to have to do some Googling, I guess.
At least the older air cooled Porsche stuff is different because the cylinders come off the block individually.
Yes Joe.
let us know what you find out
I forgot about the air cooling. I am sure that the same situation applies for the big 12 as Dan mentioned.
I did find a decent build video for the Water Cooled Porsche Flat-6 but it looks exactly as hard as I thought it would be. Knowing Porsche, they probably have a special assembly tool at the factory for getting that pin in more easily. Or maybe some special jig?
Oh, I am sorry. Obviously, the rod bolts can’t be torqued. I knew it was something simple.
The rod bolts can be torqued but the stretch which is the proper technique is used.
Love it – i wish i could have this build.
What is the copper wire diameter and how much it sticks out of the block deck?
Don’t know didnt ask
