You probably mean a valve cap. The cap keeps the valve free of dirt, so it's not the best way to do it but it's possible to drive a car without protecting the tire valve.
remove the chatter valve
Yes
Please restate the question. What are you talking about? Valve cover gaskets, valve cover, what? need a valve cover
There are valve cover bolts around the perimeter of the valve cover. You want these tight but not as tight as you can get them.
In Michigan it's leagle to run with no hood. It's illegal to drive without your bumper/cover.
As with all valve gaskets it is located between the valve cover and the head. To get to it you undo all bolts holding the valve cover on and then pull valve cover off. you will find it on the valve cover/ head contact point.
# The PCV valve is located in the valve cover # Detach the hose from the valve then unscrew the valve from the valve cover
it is on the valve cover, usually in the driver side valve cover. If you have a 2.2 L engine, it doesn't have a serviceable PCV valve, it is built into the valve cover.
mine came from the factory without one I had to get the parts and install one , but the answer : it is suppose to be at the end of the vac hose on the top of valve cover where the hose goes into the cover I had to buy the grommet and a pcv valve
Remove the valve cover.....scrape off old gasket.....clean gasket surface on valve cover....apply gasket sealent to valve cover gasket surface.....set gasket in sealent.....reinstall valve cover.
Assuming you mean "valve cover gasket", the gasket seals the valve cover to the head so as not to leak oil.
