Hi Guys I have bought a boost leak test to fit the CAI end, but can't get the pressure above 8 PSI. has anyone done one of these tests ?
If so do I need to block off any hoses or do you have a Idiots guide to Boost Leak Testing on a 2010 3 MKII.

you need to pull the valve cover breather line off the block to allow excess crank case pressure to escape, then block off the breather hose to prevent that form leaking during the test.
then start putting slight air pressure in and wait for the pressure to build. listen for leaks or spray some soapy water around joins and watch for bubbles.
Do you mean the ventilation hose that runs from the CAI to the back of the block ? and then block off the end of this pipe ?
Thanks. I'll let you know how I get on.
