"Build a diesel engine by printing it and you won't have near the gasket or leak problems that are so common with all internal combustion engines."

I only have a basic understanding of diesel engines (I've rebuilt many 2 and 4 stroke gassers)...

Why would a diesel, with higher cylinder pressure, have less stringent tolerances for seals? Less volatile / caustic fuel?

[right way right]

They don’t.
I was writing about the possibility of printing an engine more fully complete in what would be considered an essembled or nearly assembled unit by todays methods, thereby greatly reducing the amount of individual parts caused by the manufacturing process.
I’m writing about not having the need for separate heads, engine blocks, cranks, head gaskets, oil pan gaskets, bed plates etc. Its printed not assembled.
As it is today more Oil leaks on diesel engines are tolerated by consumers due to labor cost and frequency, so I was thinking more in that direction.

Being a tech my first thought is they would leak less but be less servicable
and more durable.
