These Nissan VQ35DE Oil Galley Gaskets are mounted beneath the timing cover on your 2003-2006 Nissan 350Z (Z33) and Infiniti G35 (V35) equipped with a VQ35DE powertrain. When these gaskets fails and begins to seep, oil pressure may drop resulting in potential catastrophic engine faliure. If you are seeing low oil pressure symptoms, such as low readings on the gauge, Z1 does not recommend running the engine until you have this checked, to minimize the risk of engine damage.
There are two oil gallery gaskets under the timing cover of your VQ35DE. When one fails it is always recommended to replace BOTH gaskets to ensure that the issue is resolved, as this is a fairly labor intensive job to complete and can be costly if it has to be re-done. These are commonly reffered to as 'small' (lower) and 'large' (upper.) This set includes both upper and lower gaskets.
NOTE: OEM oil gallery gaskets can not be purchased new seperate from the timing covers. Fortunately, these gaskets are available here! Made from a high temperature oil resistant Syntheseal gasket material, designed to exceed even Nissan's specifications!
