Cylinder-To-Cylinder Leakage Test

WARNING: This page is about a different car, the 2014 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.

To determine if an engine cylinder head gasket is leaking between adjacent cylinders, follow the procedures in CYLINDER COMPRESSION TEST . An engine cylinder head gasket leaking between adjacent cylinders will results in approximately a 50 - 70% reduction in compression pressure.
