I was told in order to change intake gasket the valve covers would have to be taken off and those gaskets would need replacing also. The total cost will be about $875.00 Something just doesn't seem right and wanted to check it out.
Do you have to take valve covers off to change intake gasket? on 2005 Buick Rendezvous
you can wiggle it out but not back in, remove to make it easier
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.
