Just got back from my 3000k road trip, Stag performed fine, got 10.5L/100km (9.5km/L), which i was happy with.
However, during the trip the intake developed a leak i think, idling fine but will no longer reach desired boost, about 0.05 bar below, and has a low pitch whistle sound above 0.5 bar, not there before and separate from the usual spooling sound. Done a quick check of hoses, and now thinking it may be around the turbo itself.
Anyone have any ideas on the most likely place for a leak on the turbo ? seals. gaskets etc
PS sydney drivers, the horn is not a blinker.
