Definitely yes. You cannot properly torque used head bolts. Some may disagree, but I would replace them.
Yes, they should.
If you needed a gasket and they replaced it then yes you would be charged for the gasket.
You should use a thermostat gasket along with the thermostat housing ring. The gasket should be replaced every time the thermostat housing is opened.
To change the oil pan gasket on a 1999 Mazda Protege DX, remove the bolts holding it to the bottom of the motor. Take the old gasket off and clean the area where the gasket sits with a gasket cleaner. Place a gasket sealer on the outside lip, then put in the new gasket. Carefully replace the pan and tighten the bolts, being careful not to let the gasket overlap itself.
Intake and exhaust manifold gaskets are also replaced along with the head gasket. Head is inspected and if cracked it is replaced. Head bolts should also be replaced with new ones.
you mean like k seal?, there only temp fix if that, the gasket should always be replaced if its failed
I have a 2007 ford escape, replaced a valve cover gasket in August 2012, noticed that i have a small oil leak around the gasket.
yes. it happens sooner or later
There is no set interval. It only needs replaced when it has failed.
If miraculously the pan gasket remains intact you do not need to worry about changing it. However being a 91 it will most likely break or be to hard to re seal and therefore need to be replaced.
YEs it should!! the tech is trained to accomplish all that > when a car comes in they cannot let the car leave if there is still something wrong like the radiator not being flushed after changing the manifold gasket, your tech was probably hoping that you would pay the extra cost.
if my heads are warped and gasket needs replacing what longterm damages and repairs should i expect
need to replace the intake manifold gasket
