What happens to engine if intake manifold is not torqued properly?

because it is
The prior answer is incomplete at best.
An Intake manifold for an engine is torqued to specifications that guarantee there are no leaks of vacuum, oil, or water from being ingested into the engine.
The seal on the intake manifold is critical to the eventual operation of the engine and it's correct mixture.
That being said, the torque or just the tightness needs to be sufficient for a seal and may function well if it is sealed even if it is not torqued, but it is not recommended.
As a side note, many torque values on cars are given because they had to specify something, not necessarily because it is 'critical'.

What is the difference between an intake manifold and an exhaust manifold?
The intake manifold is where the air and fuel mix and enter the engine. The exhaust manifold is where unspent gas and air exit the engine. In other words the intake manifold is where the engine breathes in and the exhaust manifold is how the engine exhales out.
Would a bad manifold gasket cause gross vacuum leak at the intake?
Yes. If an intake manifold gasket was not installed properly or has somehow become damaged the engine will pull air through the opening.
How can a rocker arm on a 1990 Geo Tracker be replaced?
By removing the valve cover from the engine, then removing the rocker nut on the bad rocker. Refer to a technical manual for torque specifications, as this must be properly torqued!!!

The intake manifold is on the top center of the engine. The exhaust manifolds are on the front and rear of the engine.
Where is the exhaust manifold located on a 1997 Dodge Avenger?
More information is needed to answer this question properly, such as; is the engine a 4 or 6 cylinder. In the case of a 6 cylinder, their are 2 exhaust manifolds; the front exhaust manifold is located under the hood between the radiator and the engine: when you check your oil level by grasping the dipstick your hand will be just a few inches above the exhaust manifold. Basically, follow the exhaust pipe(s) to the engine and where it connects to a device that splits the exhaust 3 or 4 ways, that device is your exhaust manifold.
Honda crv 1998 model you have change the head gasket but still water goes to the engine oil what is the problem?
It IS possible that the new head gasket was not installed properly - either the gasket slipped or the head was not torqued down properly or in the proper sequence (don't feel bad it has happened MANY times to LOTS of other people) - OR - there is a crack in the block itself and the engine might have to be replaced.
