LDP (Leak Detection Pump):
Most auto manufacturers that had been using a Leak Detection Pump (LDP), as an onboard leak test for the EVAP system, are in the process of completely phasing out the LDP pressure system and replacing it with a testing procedure that uses vacuum.
However, it is still important to understand the function of the LDP since there are many older vehicles that were using that system.

Vacuum Heater Controls;
To locate climate control leaks; install the The Smoke Machine™ supply nozzle into the main vacuum line leading to the climate controls. Turn it on and watch the flow meter indicator ball. If the ball drops to zero the system is leak free. Now with the The Smoke Machine™ still connected, change the heater selector lever or button from heat to defrost to vent and while doing this watch the flow meter for any indication of flow. If the flow meter indicates flow in any of these positions you will know what portion of the system has a leak. Take a bright spot lamp under the dashboard and inspect the system for exiting smoke, or use a UV light and look for the dye pinpointing the leak.

12 Intercooler & Turbocharger Leaks:
Engine compartments with turbochargers tend to run hotter than those without them, causing hoses and seals to dry out and leak. For turbocharged systems to operate efficiently there can be no leaks in the intercooler, ducting, exhaust or the turbo itself. Intercoolers and turbochargers are tested with the engine off, as with all tests performed with the The Smoke Machine™.

To test these systems for leaks, connect the smoke supply line to the intake system and introduce smoke into the "cold" side of the turbocharger. With the intake under smoke pressure, the intercooler, the ducting, the waste gate, and the "cold" side of the turbo can be inspected for leaks.

To inspect the "hot" side or exhaust side of the turbo, introduce the smoke into the exhaust pipe using the exhaust cone and inspect the exhaust, the exhaust manifold, and the "hot" side of the turbocharger.
