Exhaust Manifold Gasket

HOW TO DETECT THE EXHAUST MANIFOLD GASKETS FAILURE

You can check the part integrity visually. For this purpose, first remove the heat shield that covers the manifold, and then unscrew all the bolts connecting it to the exhaust pipe and the cylinder. Now, having access to the part, you can examine it. If the gasket is warped, became thin, or there are soot traces on it, then it requires replacement.
