A compression tester. Leak-down testing is a static test. Leak-down tests cylinder leakage paths. Leak-down primarily tests pistons and rings, seated valve sealing, and the head gasket. Leak-down will not show valve timing and movement problems, or piston movement related sealing problems. Any test should include both compression and leak-down.
Common test methods for head gasket leaks are a compression test (using a pressure gauge), a leak-down test or a chemical test that identifies hydrocarbons in the coolant fluid. [ 5 ] The cost of the replacement component (i.e. the head gasket itself) is usually relatively low, however there are significant labor costs involved in the ...
To test OBD-II scanners, we pulled a 2005 Toyota Corolla into the Car and Driver garage. We then set to work manufacturing a check-engine light (CEL) by unplugging the mass-air-flow sensor.
$07 Minimum voltage for test; $08 Maximum voltage for test; $09 Time between voltage transitions in ms; See OBD-II PIDs#Service_05 for a list. Service / Mode $06 is a Request for On-Board Monitoring Test Results for Continuously and Non-Continuously Monitored System. There are typically a minimum value, a maximum value, and a current value for ...
OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool.. SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections.
Reducing pump speed is beneficial [b] and so it is common to drive the pump via the camshaft (if this is mounted in the cylinder block) or distributor shaft, which turns at half engine speed. Placing the oil pump low-down uses a near-vertical drive shaft, driven by helical skew gears from the camshaft.
