The cylinder head has to be removed and the head gasket replaced. This is not an easy job for the do it your selfer. There are several special tools required and when the engine is apart, there are several areas that have to be checked for exact tolerances and torque settings, otherwise the new head gasket will blow. I would suggest you have a mechanic do the work.
Hopefully, it's the thermostat... but, if the engine has seriously overheated it could be a damaged head gasket caused by a warped head. Engine heads will warp slightly when the engine overheats, then there is insufficient pressure on the head gasket and the gasket will leak.
Not sure what engine you are working on but if you are using a new gasket there is no need for silicone unless the directions included with the new gasket require it.
It could be the cause of the knock only if the gasket was bad and leaked out almost all the oil.
A head gasket is a gasket the separates the cylinder head and the block. It separates the coolant passages, cylinders and oil passages. There are many other posts on this page that will provide more details. The head gasket provides a seal between the head and the engine block.
The oil filter gasket is a rubber ring that is usually bonded to the oil filter. If the oil filter has been removed and has no gasket, then it has become stuck to the engine block. Remove the gasket from the block before installing a new oil filter with it's own new gasket. Be sure to spread a little clean engine oil on the rubber gasket before installation to help seal and prevent sticking to the block. Do not overtighten the filter, turn the filter until the gasket contacts the block and then tighten 1/4 turn more. If the gasket leaks, tighten just enough to stop the leak.
Between the head and the engine block.

where can i find head gasket 2.0 diesel
An assortment of gasket scapers and plenty of patients.
My 1998 Escort had one broken exhaust bolt after the CAT and leaks which causes the PO133. Cut off bolts and replaced gasket and bolts. All is good
gasket is gone
Coolant entering the combustion chamber and the oil pan. This will cause serious engine damage and stalling due to the plugs getting wet. You should not even be driving a vehicle with a blown head gasket unless you do not care if you destroy the engine.

Gasket between engine block and cylinder head
If the engine is run while the gasket is blown, the engine will overheat and eventually blow or seize up. If the gasket blew and engine was soon after turned off, there may be no further damage to the engine. Replacement of the gasket can get this engine in working condition.
the valve cover gasket!
