cylinder head on 2003 Lincoln Navigator

what are some of the symptoms of a left cylinder head that needs to be fixed!

Asked by for the 2003 Lincoln Navigator
Are you experiencing cylinder head problems or cylinder head gasket problems? The most accurate way to test for a blown head gasket on a gasoline engine is to test for the presence of carbon monoxide in the cooling system. Snap-On, Matco (part # CO 2000), and Napa sell a tool to check to carry out this test. Another link to a supplier of this tool is Carbon Monoxide is only present if there is a blown head gasket or cracked cylinder head. I think the napa part number 700-1006. . Signs of a blown head gasket are coolant loss (frequently have to top up the coolant level of the engine without seeing an obvious leak), experiencing over heating or rough engine running or the presence of white sweet smelling steam from the exhaust. A badly blown head gasket may allow engine coolant and oil to mix.

You could have many different symptoms.
* fluid leak from the head or head gasket
* abnormal noise coming from the valve train in the head
* misfires due to bad valve or a blown out spark plug
* engine overheating from a leaking head gasket
I may have missed one, but these are the most common. Hope that helps!
