Hello, I am looking for one of you who also has a 163 at home which can help me further. I recently bought an above-mentioned C8 with allegedly turbo problems. I am newcomer to the brand. Because of strange turbo behavior I suspected leak in the vacuum system. When searching I found 2 hoses which are defective or loose and I do not know where to plug them again. This can solve my problem if necessary. Once the vacuum hose is the one from the back d the engine goes past the vacuum pump and was usually scrubbed by the air filter box. The other loose end didn’t find where that belongs. Right nearby is a bit thicker air hose thinking that is also loose and I don’t see where that should go. Put a couple of pictures with me and if one can tell me where to go with it I would be very grateful. Many greetings Asmir
