2005 Buick Rendezvous Question: Do you have to take valve covers off to change intake gasket?
you can wiggle it out but not back in, remove to make it easier - globalhelper
Anwser to your question is yes......the covers do need to be removed. Assuming you need lower intake manifold gaskets replaced.(Do you have a coolant leak I wonder?) The price quote is fair for that job also. Get a second opinion if you want. - milesauto
