Today, I did another round of pressure testing on the engine through the MAF area of the intake. Sure enough I found a leak at the coupling to the intercooler intake. The hose was starting to work itself out. Second time, same place in a short period of time. What is the fix, new clip, new stock hose, aftermarket? The car has a Ruf kit which seem to want to boos to 1bar. I also sprayed the rubber hose which feed fresh air to the compressor side of the turbos, and the thing is leaking like a sieve. I had no more than 10psi in air it started making bubbles within seconds or reaching the area. I realize these hoses never see boost, but it still surprised me. Any feed back on this? I bet the stock contorted plastic piping doesn't leak like that.
