Absolutely not. The two are not related in any way. If this was just a personal concern, just replace the intake manifold gasket. If this was what a repair station has quoted or already charged you for, Id go somewhere else or talk to a lawyer respectively.
By replacing the whole gasket.
Irratic idling condition is indication of intake/inlet manifold gasket leak. Change gasket immediately. This particularly applies to EFI engines. Newaz.

The manifold gasket is the same as the plenum gasket. The manifold gasket is a barrier between the manifold and the engine block.
About 450.00
It's supposed to do that.
Get a shop manual. This is a complex procedure.
oil in the radiator water is normally caused by a faulty inlet manifold gasket.
The cost varies widely depending on the make and year of the vehicle.
Drain the radiator. Remove the radiator hose. Remove the inlet from the engine. The thermostat is in the inlet. Replace the inlet and the gasket, and reverse the procedure to finish the procedure.
If is oil then you have a bad intake manifold gasket. If it is transmission fluid then the cooling tank in the radiator is bad.
No, You don't put anything on Head, Exahust or intake gaskets. CJ actually you do put a 1/8'th inch bead of black silicone on the gasket to ensure no leaks occur and it also helps hold the gasket in place when your putting the intake manifold on. I'm a ford master technician, you ALWAYS use silicone when replacing intake and head gaskets. =DK
