Exhaust manifold gaskets are not often an issue. Do you have a problem with them?

no i dont think if i did i would hear a exhaust leak right.....

Intake Manifold Gasket - look for coolant where the intake manifold bolts to the heads. If you see coolant there, try to locate the source. If it is not coming form any place like the TB, a bad hose, thermostat housing, or any other place and it (coolant) is only where the intake meets the heads, then I'd say your gaskets are probably bad. Otherwise the gaskets are probably good. - BC

PS - any water/coolant on the dipstick. - BC

I'd still do it as preventive maintenance when you get the time and money. It's not if, it's when.
