compression question

When doing a compression check by adding a teaspoon of oil to a cylinder .If the compression remains the same ,does that mean its a bad head/valve ? on a 360 small block


If the wet compression is higher than the dry compression, then there are problems with the rings and bore sealing...

If the wet compression is the same as the dry compression, the rings are fine and you need to look at the valves and/or head gasket....

If you know which cylinders are low, then do a leak down test to see if it's in the intake valve, exhaust valve, or crank case...
