Frequently Asked Questions

Does this seal a vacuum leak at the manifold?

Yes, provided the manifold and head faces are clean and flat. A warped flange needs attention before the gasket will seal.

How do I check for an intake gasket leak?

With the engine idling, spray a little carb cleaner along the manifold-to-head joint; if the idle changes, the gasket is leaking unmetered air. A high, hunting idle is the common sign.

Any tips to seal the manifold?

Clean both faces to bare metal, check the manifold is not warped, and torque the fasteners evenly in sequence so the gasket seals without distorting the flange.
