Hi there, I'm just gonna start by saying that I'm a musician and know nothing about cars. My 07 GTI has a pretty bad oil on the left side of the car. It seems to have spread everywhere pretty bad and I can smell the oil inside the car when I drive. It seems to me, after reading forums, that it could be the PCV. Before I get it in the shop I would like to have the engine cleaned so that the work can be done faster and more efficient. I heard that I should get the engine steam cleaned but I want to make sure that it is a good idea and if so what to expect from something like that. Any advice will help as I am a broke ass musician living in LA. However, in exchange for your help please let me know if you have any questions about guitar or audio recording. I'd love to help. Thanks!
