some,enough to pull blowby out an recirculate it into the intake,to much and you implode seals and gaskets,causing oil leaks and pulling debris into the engine.
that must be some metro to have a big block
Haynes repair manuals have good vacuum diagrams
a good engine to put in a car i think is a 350 small block with a twin turbo. another is a 440 big block v8 with twin headers
Test it with a vacuum gauge.
The engine does not produce enough vacuum to be usable.
20 in hg at idle is good.
The engine is the vacuum pump. All the vacuum operated accessories are operated by the vacuum supplied from the engine.
A gasoline engine makes it's own vacuum. The diesel engine has a vacuum pump next to the power steering pump.A gasoline engine makes it's own vacuum. The diesel engine has a vacuum pump next to the power steering pump.
no.

A cracked "engine housing" probably means a cracked block. Very not good. A new engine will most likely be required to fix the problem, as a cracked block is next to impossible to repair.
As you are looking at the front of the engine, it is located behind the vacuum pump; bolted to the block.
