Frequently Asked Questions (FAQs)

Why should I choose OEM gaskets over cheaper aftermarket options?
OEM components are designed by the same engineers who built your specific engine layout. They utilize exact material thicknesses and structural compounds needed to withstand factory operating pressures, whereas generic aftermarket options often use inferior materials that shrink or fail prematurely under high thermal loads.

Do I need to use liquid gasket sealer or RTV during installation?
Generally, no. Factory gaskets are engineered to seal perfectly dry or with a very light application of clean engine oil on specific rubber surfaces as outlined in your factory service manual. Applying excess RTV silicone can squeeze into critical internal oil pathways, causing fluid starvation and catastrophic engine damage.

What causes a factory cylinder head gasket to blow out?
The most common cause is engine overheating. If your radiator gets packed with trail mud or a coolant hose leaks, the excessive heat can cause the aluminum cylinder head to warp slightly. This warping breaks the uniform crushing force required for the head gasket to lock in combustion pressures.
