Finally, reconnect any components you removed and the battery.

Angle tightening head bolts is a method used to ensure a secure and uniform clamping force in bolted joints, particularly in applications like automotive engines. After initially tightening the bolts to a specified torque value, an additional angle of rotation is applied, measured in degrees. This technique helps compensate for factors like bolt stretch and gasket compression, providing a more reliable seal and preventing leaks. It is commonly used in conjunction with torque specifications to achieve optimal performance and safety in high-stress environments.

Blue smoke from the exhaust when the AC is on typically indicates that the engine is burning oil. This could be due to worn piston rings, valve seals, or other internal engine issues that allow oil to enter the combustion chamber.

Yes, a blown head gasket can lead to carbon buildup in the cylinders, particularly if coolant or oil leaks into the combustion chamber. This contamination can cause incomplete combustion, resulting in carbon deposits. Over time, these deposits can increase the compression in the cylinders, potentially yielding higher than normal compression test pressures. However, it's important to diagnose the underlying issue, as other factors may also contribute to elevated compression readings.

The cylinder head consists of several key parts, including the combustion chamber, valves (intake and exhaust), valve guides, valve seats, and spark plugs (in gasoline engines). It also contains passages for coolant and oil, along with mounting points for the intake and exhaust manifolds.
