Spent the afternoon under the front N/S corner of the 04 Cayenne Turbo, looking to replace the seals on the boost hoses and dump valve. When unclipping the bottom turbo hose from the intercooler, I was stunned to find at least 1/4 litre of oil pour out of the hose onto the floor. In all my years, I've never taken a hose off a turbo and seen that much oil. Has anyone else on here taken the hose off the bottom of the intercooler on the N/S (Drivers side US & Europe, Passenger side UK) and experenced it full of oil? I'm worried about the state of the oil seals on the N/S turbo. Is this a feature of the Cayenne's turbo design?? I replaced all of the seals on the hoses at the O/S earlier in the year, and the bottom hose was dry. This N/S hose is shaped differently, but should it collect 1/4 litre of oil like this? Thanks Chris
Need your guys help & expertise please I've been trying to find the cause of the P0299 underboost code for a while now and after randomly stabbing in the dark by changing intercooler, Y-piece, hoses, N75 valve, I read a really good post on here (in the 996 section) about pressure testing. I've spent the last few weeks, getting a gauge, schrader valve, fittings, and various sizes of hose so I can T into the lines of the turbo system (it was the offside turbo to bottom of the N75 I actually Tee'd into) and yesterday, tried to test the system using my compressor. The more I think about it, I now realise that I would have to plug both of the airboxes and the throttle I think. Has anyone performed an intake pressure test on a Cayenne Turbo on here? If so, What is the best hose to T into? How many hoses do you have to block off? Do I have to remove the throttle body and blank behind it? Thanks in advance Chris
