I know this is going to sound like a very very stupid question…
Why are engines designed with a top and bottom half?
By necessity? Why not have it just be 1 giant part?
One giant block with valves on top, and crank on the bottom.
This would eliminate the need for a head gasket…
Obviously, there is a very good reason for this…But what is it?
Is this b/c of assembly issues?
Can’t get the piston inside?
Or is it for maint. issues?
