The check will reveal any leakage and enable you to detect whether the cause is worn piston rings, a blown cylinder-head gasket or a valve that is not seating properly.

What is the unconfined compression test?

Unconfined Compression Test (UCT) is a simple laboratory testing method to assess the mechanical properties of rocks and fine-grained soils. It provides a measures of the undrained strength and the stress-strain characteristics of the rock or soil. The unconfined compression test is often included in the laboratory testing program of...
