right stripped the plenum off again, to sort a water pipe out that came off. coincidentally the std clamps don't work too well on silicon hoses lol. found a few t clamps so sorted that

 

but their is another air leak i found just before i stripped it back, its down the rear of the engine where the egr is....? right i've replaced the hose on the egr, its not that, when i took it apart i check the plenum gasket( not that)

 

i cant see any other air pipes down there what could it be its really confusing me,

 

anyone know of anything else down their could cause a leak? can hear it when driving (especially as the turbos spoil up) did a boost test using the space saver so me psi and its defo round the egr.

did you check the clutch assistance... I've seen a few threads that point to that as a possible vac leak area.

mines an auto,

 

its very close to the egr its just their is nothing else down their lol.

LOL... oops... :D

 

I'm currently looking into finding some sort of smoke to run though the induction system to help track down leaks...

something like this...

but got to make sure there is no detrimental affect on the car....

i had a similar thought, they tend to leave a residue behind and im not sure what it would do.

 

i was thinking if you sprayed it round the area, during a boost test it might help find the leak?

pulled the plenum again, (this time i bypassed the water pipes,) actually easier then i thought it would be

 

egr is still on the car although i did find the exhaust manifold bung, just cant get to it with the engine in lol.

 

can happily tell you its fixed!!!! just took it for a test run and its just like it was before. :clap:

 

the air leak was a crack in the rocker cover??!! swapped it for a spare cover and all fixed yay!!:thumbup::clap:

:thumbup::thumbup::thumbup::thumbup:

I just found my ones as well... well I think i did anyway... elbow pipe going back into the rocker cover form the PCV... really loses... going to test it tomorrow...
