Just wanted to start a thread of machine work in progress and the final product. For block Sleeving and parts production.

After cutting of the block for closed deck sleeves

Thanks for sharing these shots with us here. Please continue to do so. I enjoy seeing some of the work. Whats the difference between the two sleeves in the first two pictures. I guess more or less the significance of the shape of the sleeve is what I am curious about. And are those in the same kind of block?

 

The first two are b series and the differance is the water channel that is cut in the top for a pocket of coolant directly on the gasket. It aids in several ways. One being it leaves stagnat coolant directly on the gasket as the factory open deck provides. Two, it decreases the total surface area that the clamping is distributed on creating higher clamping load around the combustion chamber leading to a better gasket seal. All of the blocks are also stepped decked to aid in clamping force and thermal expansion of the aluminum.

The weekend workload

 

This is where I spend alot of time. But it's what I love to do.

 

Thanks for the explanation. I really appreciate it. And please keep posting pictures.

 

Interesting... your saying the block in the second pic will have better clamping load for the head gasket to seal? I would have thought the first pic would have the best head gasket seal do to more surface area it has for the gasket mating surface.

Nice work btw!

 

If X amount of pressure is pressing down on more surface area then the psi is lower. Same pressure less area higher psi of clamping load.

 

any pictures of the process of the sleeves being pressed in?

 

Install

 

O-ringing a b series closed deck

 

Makes sense. So do you only reccomend o-ring's on the closed deck block or?

 

o-ringing the block? is that a set up for nitrogen filled rings that can be ordered from Cometic?

 

Copper or stainless o- ring groove either one depending on application

 

do you really press them in like that? or one at a time?

 

Nice work Howie!! Now get back to work!!

 

I love looking at this stuff.

 

It's nick and send me another I like that d series stuff. It's like fixing a dinasaur... Lol

 

I start them by hand and a dead blow hammer then press 4 at a time till the flats are below the deck the. Press individually. Then a deck plate goes on till the temp. Equalizes to room temp.
