Wet compression test If a piston ring is leaking, this type of test will indicate some compression. If a valve is burned, this type of test will make no difference and indicate the same readings Blue Smoke this means the engine is burning oil. Could be caused by worn piston rings White Exhaust Smoke caused by coolant leaking into one or more cylinders, such as when a head gasket goes bad Worn valve guides and vacuum readings this condition would cause the vacuum gauge ne...

ASVAB Study Guide Questions and Answers with Certified Solutions the intake valve opens as the connecting rod pulls the piston down, drawing the gas/air mix into the cylinderse intake cycle the valves are closed, the connecting rod pushes the piston up, compressing gas/air mix compression cycle the spark plug ignites the gas/air mix, forcing the piston down. that pushes down on the connecting rod, turning the crankshaft; the crankshaft turns the flywheel, which keeps the engine going power cy...
