How to pressure test?

[Alex B]

I'm doing a pressure test to find any boost leaks, but I'm not 100% sure I'm doing it correctly.

I've blocked the AFM pipe, blocked the breather to the rocker cover and attached a tyre valve to the actuator pipe, i've found a few leaks so far.

Is this the right way of doing it?

I can hear quite a big leak down near the turbo but can't see where it's coming from, any ideas?

Thanks

you need to block the inlet to the engine too.

I wondered, thats gonna be difficult with a hard pipe kit! :-(

Yeah I found it last night, I managed ok, just not much movement on the hardpipe to the plenum but I managed to firce it enough.

i get some soapy water as well, and wipe it on thick around all joints/joins/bends etc, pretty much over the whole lot. as it will bubble up where there is a leak. easier to find leask like that, than trying to hear them
