Do I tell if a DV is leaking air out the trumpet by leaving engine running on tickover and putting my hand over trumpet - Would I feel an air leak?

 

Thanks

at idle there will be a vacuum so i'd expect the air to be leaking IN to the system.

so do I get someone to lighlty press the loud pedal to see if I can feel air coming out?

No because then they'll seal under boost lol. You can usually hear a hissing noise coming from DVs if they are leaking at idle...

Cheers Andy, as is I've temporarily binned them for the original recircs!!

sorted out the stalling prob now though which is good

 

just gotta check for boost leaks now coz Im still not running above 5psi

Could be the elbow as it comes off one of the turbos - seen quite a few of these work the clamps loose somehow - not toooo bad to get to but expect a few scratches lol
