Hey there,
I have a problem with my mk1 RS, it seems that it has somewhere a leak in the pressure side of the intake system, but i canīt find one. when under boost, starting at about 0.4-0.5bar you here a loud blowing noise. And right at about 5500rpm+ it sometimes behaves like it has misfires. I mean short time of no power.
I searched the hoses for leaks by demounting them and set them under pressure. I did the same for the chargecooler. I also checked the blow off valve, which also seems to be ok. So there is just the inlet manifold left to check, but I donīt think that it has a leak, and because itīs quite an efford to demount it, I ask here if you guys maybe had once the same problem with your RS.
Please excuse my bad english, but Iīm from Austria. Post all your suspicions, maybe one can help me because Iīm really desperated
