what are the signs for replacing the oil gasket in a 1996 Chevy cavalier
There is not gasket between the engine block and the oil pan. A sealant was used to join the two. If you are leaking oil from the pan you might try checking the bolts and making sure they are snug. If they are snug and it still leaks get tube of gasket maker to reseal it. Be sure to get all the old sealant off the pan and the block before you reapply. If the pan is leaking, you MUST remove the pan and install a gasket. Usually cork. I know of no mechanic that has had luck just using the sealant that a manufacturer uses. That is why Oil Pan gaskets are available for just about any car out there.
I believe that if a gasket is employed, then the need for gasket seal in a tube is gone, however, your gasket should be torqued to manufacturer's specifications. Yet, it doesn't hurt to have both.
To remove the oil pan on a 5.2 Dodge Ram van, start by draining the engine oil and removing any components obstructing access, such as the exhaust and crossmember if necessary. Next, unbolt the oil pan from the engine block, carefully prying it loose if it's stuck due to gasket sealant. Ensure all old gasket material is removed from the mating surfaces before reinstalling or replacing the oil pan with a new gasket. Finally, reassemble any removed parts and refill the engine with oil.
