Very quiet garage to listen for leaks вЂ“ beware of neighbors watering the lawn.

Compressor w/ regulator, GOOD pressure gauge, hose.

So after playing with all the new gadgets I wanted to test the system w/o removing any parts that are exposed to boost pressure. OK, I had already made several fittings to tap into, plug and pressurize sections of the OEM intake system.ДЄfter removing sections of the intake system and checking them independently, it was obvious they could leak when they were put back together. YouвЂ™re not done till the 30FFвЂ™s stop popping up. Just remember that there can be more than 1 source for the 30FF. You can start with the tests you already have the tools or time for and stop if you are lucky enough to detect & fix the problem. The sequence of the tests is not so important. Turbo compressor operation(HOT side) вЂ“ a. Turbo compressor (COOL side) to intake manifold/head interface. Since 30FF can be from a leak in the pressurized section of the intake track and/or the turbo just isnвЂ™t putting out enough, I broke this up into 2 areas:ДЎ. Thanks to: Terry for supplying lots of technical data via a few dozen emails, and Rob RB. Spent a lot of time the past week trying to diagnose a 30FF. not the Chinese fakes going around) in stock and ready to roll for $99 each: Should you determine you have a faulty or worn solenoid, we've got brand new OEM quality (e.g.

If vacuum is 18' or higher with DWP = 100 then you likely have a blown off chargepipe or intercooler pipe.

We suggest first looking for obvious leaks like a blown off chargepipe, loose diverter valve, missing oring or meth bung plug from chargepipe (if newly installed), and then if you can't find anything do the vacuum line test shown in this video before digging deeper in to possible boost leaks.ДЄfter doing the test in the video if vacuum remains at 0 or low regardless of the DWP JB4 setting then you likely have a vacuum line leak, faulty JB4 board, wiring harness issue, or faulty boost solenoid. This thread discusses searching for boost leaks and vacuum line leaks on cars where the boost target is normal, JB4 PWM (duty cycle) is high, but boost is heavily below target.
