Timing Belt

A belt that synchronizes the rotation of the engine's crankshaft and camshaft, ensuring that the valves open and close at correct intervals.

Relative Compression Test

A quick way to identify a weak cylinder by cranking the engine with an inductive ammeter on the starter circuit. With a lab scope, cranking amperage can be graphed and correlated to a particular cylinder. A cylinder with low compression will draw fewer amps than a cylinder with higher compression, which will show on the graph.

Inductive Ammeter

An instrument used for measuring electrical current without the need to make direct contact with the conductor.

Black Smoke
