    hey, does anyone have pics of what the most likely places for boost leaks are and where they are in the engine?

    also how do you go about pressure/smoke testing the system?

    cheers

    Under the inlet manifold (all the vac hoses down there), busted DV, and intercooler/s where the core joins the end cap.

    cool thanks, I'll check it out under the inlet manifold, are they easy enough to see or is there anything particular i can do to get better access or to test them?

    Thats the only way to be able to see properly. Two allen key bolts, BE CAREFUL of the dipstick shroud - it will most likely be brittle and break.
