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.......
Unless the housing is damaged, there is no reason to replace it. Just replace the gasket.
How much should it cost to replace a blown head gasket for a 197 BMW 528I
you mean a valve cover gasket i think
Replace the head gasket for sure. That is assuming you did not continue to drive the vehicle until you destroyed the engine internally.
To replace the head gasket on a 1994 Oldsmobile Cutlass 3.4L, everything on the top of the motor needs to be removed. The battery should be unhooked first, then the valve covers, then the head itself. Replace the new gasket after cleaning the old gunk off from the first gasket. It is a good idea to take a picture before, during, and after, to make sure everything is hooked up like it should be. One note, the valve cover gasket will also have to be replaced after removal.
should you drain oil in the car if the head gasket is blow
YES! Replace the head gasket or destroy the engine if you continue to drive it.
There is no way of knowing until the engine is taken apart and checked. What you would hope to be a blown head gasket may turn out to be a cracked head(s) and that would bring the cost up alot.
For sure, replace ALL the gaskets involved. When you purchase, ask for a head gasket set and you will get all the gaskets that are used.
You cannot and should not buy a used head gasket. If you have a blown head gasket you replace it with a new gasket. The gasket will cost very little. The labor to replace the gasket is where the cost is. Expect to pay from $500 to $1,000. This is a major repair that takes time.
Gasket should be included with new oil filter
