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.

In most cases a new gasket is required, but no sealant.
You need the sealant on the ends where the supplied gaskets don't cover fully.
Not that I've heard of. Replacing the gaskets and inspecting the manifold for warping or cracks is the best way to stop intake vacuum leaks.
what is the general cost for sealant replacing in expansion joints
Yes, wherever there is a joint between 2 pipes, use exhaust sealant to prevent a bad seal between the pipes, which will prevent it blowing.
There should be a stud (not a bolt) threaded in to the head and the stud should have a thread sealant applied to the threads.

When replacing the intake manifold gasket on a 1994 5.7 engine, apply silicone sealant to the corners of the intake manifold where it meets the cylinder heads, as well as along the front and rear of the intake manifold. It's also recommended to use a thin bead of silicone in the areas where the gasket will be seated to ensure a proper seal. Avoid applying silicone on the entire gasket surface, as it can cause leaks. Allow the silicone to cure as per the manufacturer's instructions before starting the engine.
On the 3.1 LS model, the thermostat is in the intake manifold, just underneath the air intake, and between the exhaust crossover and the manifold. Trace the upper radiator hose back to a metal pipe from the engine, that is the thermostat housing. Replacing it means using a ratcheting box-end (10mm?) or open end wrench to start and finish, and fingertips for the rest, so NOT when the engine is hot! The thermostat fits horizontally into the manifold, and comes with its own molded gasket, which fits into a recess, and doesn't require gasket sealant. I just changed mine, so good luck.
when replacing a frost plug u can use a sealant but only use silicone u dont realy need it and yes u have to clean the area good
From experience I would say yes
Yes, it is advisable to use a sealant when replacing a freeze plug. This helps ensure a tight seal and prevents coolant leaks, which can occur due to the expansion and contraction of metals in temperature changes. Make sure to choose a suitable sealant that can withstand high temperatures and is compatible with the coolant used in your engine. Proper installation with sealant can enhance the longevity and effectiveness of the replacement.
