Auto Technician tool of the trade: Compression Tester Kit. Automotive Technicians will do a compression check on any engine they don't know the history of or suspect a problem with. It can tell you if the compression of the engine is down because of worn piston rings, defective valves and seats or a blown head gasket. #TheMoreYouKnow | Oklahoma Technical College | Facebook
