The unit is pressurising thru the elbow rubber that runs down into the turbo intake.
I did use this previously to find a lot of leaks - at the injector blocks, and all over the place. Pulled the engine, new injector blocks, intake seals, replaced hoses etc. Now I try and test again same way, I get no pressure at the clock gauge. The system is able to pressurise with relatively little gas flow - so even if there was a leak at the brake boost T or similar, the pressure should still show on the gauge.
I also tried pressurising off the nipple on the intercooler - than runs to the waste gate - same result. The butterfly is ever slightly open at rest - as it is supposed to be - and without the intercooler, I can detect gas passing it - altho I did try opening it to see if any difference- none.
The unit cost about $5 - from plumber hardware, and 1/2 hr in shed.
