I am replacing the head gasket on my toyota do i need to replace the exhaust and manifold gasket too????? or can i reuse the old ones?/??

 

You "could" reuse them. I would not reuse the intake gasket though. If you do you are guaranteed to have a leak. Reuse the exhaust though...seems like a complete waste.

Just buy a complete top end gasket set...it will come with timing cover gasket which you might not want.

 

replace EVERY gasket you come across during your head gasket job. they are cheap and you do not want to tear back into your motor because a $.50 fuel rail gasket is leaking.
