Went to change my VCG's, cam tensioner gaskets, and plugs today. Two snags: could not get get spark plug wires 4 and 5 out. Tried everything, even a generic plug remover from NAPA. Anybody else have this problem? Is there a special Audi tool for removing stuck plug wires? Any ideas? Second, I had no luck using the 3366 tool to get the cam tensioner loose enough to get the half moon gasket, and metal gasket out. I could only get like 1/4" of space. Any ideas? So, I ended up just replacing the VCG on the passengers side. Certainly did not accomplish everything I wanted too. [:@]
