Hi All !
An update
Cylinder head assembly

Hi Roger B !
First, I defined the holes in the paper..with the cylinder head using the tool in the picture ,

Then I cut the sample paper to the size of the cylinder head - but slightly larger about 0.5 mm . I also cut 0.5 mm thin aluminum and paper to make gaskets
I do as shown in the picture

Finally, fix them together with bolts and cut the size of the template and grind the edge of the aluminum gaskets, and cut the paper gaskets according to the aluminum gaskets.

Thank you :) I see you also use a template. I have been using an aluminium template and hardened punches with high temperature gasket material. I was wondering about using the same methed to make some thin copper shims to adjust the compression pressure.

Hi All !
An update

I'm back with my project.
I'm planning to do the oil pump after testing the engine but I hate to take the engine apart so I decided to do the oil pump, anyway it's better to have an oil pump :)

Hi All !
An update :

Checked the gearbox, everything is fine, but I can't assemble it yet because I am missing a lubricating oil tube for the cylinder head, I ordered small brass tube

While waiting for the small brass tube, I made the fuel filter

I don't intend to assemble the pump body into the engine block as I haven't finished it yet , but it was too difficult to install, so I decided to install it first.

looking great !!!. if it were mine I might have made the heads not-to-prototype so that more of the rocker arms would be visible when the covers are left off, its just a personal quirk that I like to see exposed rocker arms on my engines.
 
Hi Peter !
I'm a bit different from you ;), I like every part that can be seen when the engine is running and it's really fun to watch
 
Hi All !
Just an idea and experiment but the result is too good

Hi Andy !

That part to adjust the amount of fuel by changing the stroke of the plunger , and it also adjust a relatively equal amount of fuel between the cylinders
Just need 4 sets, I make 6

An interesting idea :)

Do you have a means to balance the injection timing accross all 4 cylinders?
 
Hi Roger !

Do you have a means to balance the injection timing accross all 4 cylinders?

That's a question that I really...can't answer
With the single cylinder engine I did, I know the injection time - exactly the lobe starts to contact the plunger - is between 22 and 45 degrees before TDC ( 22 is from 19 to 22 . 45 is from 45 to 47 and I would say 22 to 45 and that would be the correct number)
Balancing the injection time for 4 cylinders seems impossible to me - at the moment. Because it depends on the spring force of the needle and the pressure in each cylinder
With the force of the spring of each needle: I will try to adjust to be able to vaporize as much oil as possible
With the pressure in each cylinder , it depends too many factors such as cylinder , ring , piston ....
With this engine, I will choose the injection time to be 25 degrees before TDC and when the engine runs (hopefully it will run) I will adjust more
It's so small and I can't control everything, all engines I've done I'm pretty confident it will run , but with this diesel engine : will it run? And how does it run? I'm not sure
