What's the difference between gasket maker and gasket sealer?

Most “sealers” and “gasket makers” are RTV Silicone, same thing. Surfaces need to be clean and dry, apply sealer to mating surfaces / gasket sides ( I coat them all ) and wait a few minutes, install parts, tighten bolts in sequence, wait a few more minutes, re-tighten bolts to spec .. cure overnight.

Do you use gasket sealer on exhaust manifold?

Is it normal to have oil in the intake manifold?

When oil cannot pass freely through the passage, it gathers inside the top of the cylinder head. When the passage is totally blocked, the oil will go through the PCV valve and enter the air intake manifold. There is nothing to be worried about if it is just a light coating of oil.

What happens if your intake manifold is leaking?

A leaky intake manifold sucks outside air in, rather than dispersing air out. This can cause performance issues including poor fuel economy, decreased acceleration, and engine misfires. Coolant leaks can cause the engine to overheat, although they may not always be visible.
