Tests to measure iron levels include: 1  Serum iron. 2  This test measures the amount of iron in your blood. 3  The level of iron in your blood may be normal even if the total amount of iron in your body is low. 4  For this reason, other iron tests also are done. 5  Serum ferritin.
one symptom of a cracked manifold will be a visible crack that you can see on the manifold s surface to look for a crack look closely at the manifold particularly where it bolts up to the motor and where the most heat will be
The intake manifold directs the air-fuel mixture in the engine to the corresponding cylinder where it is burned to produce power. The coolant flows through the intake manifold to the cylinder heads to reduce engine temperature. Expansion, contraction, and heat from the engine cause the gasket to fail. This will cause coolant passing through the intake manifold to leak. A leaky manifold gasket can also result in air being sucked through the leaky gasket, resulting in a vacuum leak and poor engine performance.
