Only on a few engines will you find re-useable valve cover gaskets. If you are changing covers you are not likely to get a good seal if you transfer a reuseable gasket from the stock cover. Keep in mind that most engine fires start from oil leaking from the valve cover running onto the hot exhaust manifold. You will be money ahead buying a new gasket.
no no no no no. never use liquid gasket
Yes, a gasket goo is always advisable for valve covers.
To replace the valve cover, you will need to break the gasket and the o-rings. The gasket prevents oil from leaking.
No you do not.... the valve cover only bolts to the head, and the head bolts to the block... True- these are two different jobs. When changing your valve cover gasket you may just want to ensure that your head bolts and lifters are still torqued down properly. Otherwise, DO NOT remove the head gasket if you simply want to change the valve cover gasket. when replacing the head gasket you should replace the valve cover gasket and may need to (depending on make & model) replace the egr gasket, intake mainifold gasket, and exhaust manifold gasket ...but not the other way around. If your replacing the head gasket ask your local auto shop if they carry a head gasket kit that includes everything necessary in one box...but if your just changing the valve cover gasket then just change that.
Changing a valve cover gasket really has nothing to do with an engine starting or not. You need to check your power and gas for problems in starting.
Valve covers aren't structural, they just need to be torqued down har enough to get the gasket against the cyinder head to be oil tight.
No
no gasket sealant needed. Just original gasket is fine.
no, but it does mean you need to replace the valve cover gasket.
If you are using a new gasket, no.
you should only change the gasket if you have to take the valve cover off....... you should only change the gasket if you have to take the valve cover off.......
I'm currently working on a 97 grand voyager and need to get the valve covers off. by the looks of things the intake has to come off for the valve covers to come free. Other than that 2 bolts are the only thing holding the valve covers on. It's a real p.i.t.a. just for them 2 bolts but to stop the leaking oil its well worth it! Hope this helps you... Troy~
