Remove all the spark plugs and turn the engine over by hand. Place your thumb over the #1 plug hole and you will feel the pressure on the compression stroke. A compression gage will also tell you when you are on the compression stroke.

What would make a piston on a Chevy 350 have no compression?

The lack of compression in one cylinder of a Chevy 355 engine could be caused by a number of issues such as a leaking valve, a blown head gasket, a cracked piston, or improper sealing of the piston rings. It is recommended to perform a compression test and further diagnostic tests to identify the exact cause of the low compression in that cylinder.


How do you know if your Chevy 350 is internally or externally ballanced?

One way to determine if a Chevy 350 engine is internally or externally balanced is to check the harmonic balancer. If the balancer has counterweights welded to the outside, it is externally balanced. If it does not have any counterweights visible on the outside, it is internally balanced. It is always best to consult the engine's specifications or a reliable source to confirm the balancing type.

How do you find top dead center on a Chevy 350?

The # 1 plug on a 350 is the front plug drivers side. Turn the engine over by hand with all the plugs removed. When the # 1 piston reaches it highest point on the compression stroke, you are at TDC. A screwdriver inserted in the # 1 plug hole will show you when it reaches TDC. Warning!!! Only turn by hand and do not use the starter. You can tell if it is on the compression stroke by placing your thumb over the plug hole while turning over the engine. It will push against your thumb on the compression stroke.
