New guides are assembled, Valveseats are cut (0.1mm then it fits)

Final assembly with fresh painted parts Big Grin

TDC

With the CAD Model of the Cylinderhead Gasket, i am very versatile with compression ratio, to level the mechanical work, mybe for a deep milled cylinderhead.

I can cut the Gasket with many differnt materials, different sizes, with a copper rinf for better sealing to the cylinderhead, or to seal better wet cylinderlinders in the OM606 Big Grin

.

Also this engine gets the 9mm elements for better performance, higher efficiency factor and lower amount of Diesel in a 2.7t G Wagon (empty).

When i had run the Motor, im not sure if i can run it over idle, so i dont did it. Very Powerful!

Nice work. What did you use for pistons and connecting rods? And 9mm elements, custom made?

In those idle videos it sounds and shakes like one cylinder is completely dead.

Hi,

Pistons are special made from a little company here in Germany.
They made also Pistons for old engines, where no spareparts are aviable.
The connecting Rods are also special made. The manufacter, i dont now at the Moment, i have to Check it. But i have to do some mechanical work on it, bore the piston pin hole, and hone the bin end.

9mm elements are also special made, from a little company in northern Germany. The grind it from my drawing.

Yes it Sounds a little bit so, but each cylinder fires good.

The engine has to Run in the car, there it is bolt down and nothing can fly away and laying on the ground.

I send a Video when it runs in the car, and the whole assembling oil are gut (-:

Best regards Steffen

Hello,

thanks!

Hm i think not much People want to spend so much Time and Knowhow in this engine, when it runs also with 3.0liter.

So it is not just to bore the Crankcase to 89mm and everything fits.

The parts for one engine are too expensive, so i have parts for two more engines.
Pistons, Connecting Rods, Crankshafts, Headgaskets and so on.

Best regards Steffen
