how much am I looking at to get a intake valve cover gasket replaced

Hello. I think you might have some terms mixed together - Intake Manifold Gaskets and Valve Cover Gaskets are two separate items. If you want to repair an oil leak from the valve cover gaskets, you're right about $310 for both gaskets, labor, supplies, and tax. The intake manifold does not require removal for this job on your vehicle so no gaskets would be required. Please feel free to contact us for an appointment!
