Intake pressure testing

[wayno1]

Ive fitted a larger intercooler and wanted to pressure test intake system and check for leaks.

Should it hold pressure the way I have it set up? Cheers

Looks alright. Don't forget that the throttle body connector is a frequent cause of leaks whether it's split or just slightly popped off.

I put the pressure up to about 15psi and can hear air in intake and coming out of oil cap when I unscrewed it.
Is this the turbo bypassing into oil system ?

There is a cut in turbo seals so I guess that it is entirely possible.

Yes.  Test from turbo compressor outlet.
