Exhaust Manifold Inspection

WARNING: This page is about a different car, the 2005 Mazda RX-8. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION:

Do not reuse the gasket and self-lock nuts on the joint area between the engine and exhaust manifold.
If a gasket with detached crimps is used on the joint area between the engine and exhaust manifold, exhaust gas will leak. Be careful not to allow the crimps to detach from the gasket. Do not use a gasket if any crimps are detached.
