A vacuum when you pull the dipstick is normal and expected when engine is running. The greatest vacuum is at idle, the PCV is sucking air out of crankcase. Now a a vacuum leak around spark plug wires is beyond me.

If you hear vacuum when the seal is broken around the plug wires where they go into the valve cover you probably need a new valve cover gasket and spark plug well seals.

I will go tomorrow and get the gasket then so you don't think it's anything major then?

The spark plugs are set deep in the valve cover on a hemispherical head meaning that the valve cover has a seal around the spark plug well. The seal that keep oil out of it is allowing air to get by and giving the suck sound. When you remove the dipstick you are giving the vacuum another easier path to flow thus the sound going away. The only thing I wonder about is how much vacuum its actually pulling and if there is a vent that is stopped up causing to much vacuum to be pulled on the crankcase. Ive seen crankcase breathers clog and cause the rear main seal to give off a sound like an oboe reed.

The pcv system pulls vapors and any pressure out of the crankcase but it isn't supposed to suck it down til any of the gaskets or seals fail.

The small tube that comes off of the inside radius of the intake elbow should lead to the crankcase breather.

Do you know where that is located at?

That is on a 03 tiburon because I can't find it

none of the info that i have tells me exactly where the breather is but it should be somewhere on the valve cover. pcv system short answer. fresh filtered air from air cleaner to crankcase where it isn't submerged in oil (Usually the valve cover) back out of the crank case with a one way valve (pcv) to the engine side of the throttle body for the most vacuum available.
