I have been chasing this tick for a very long time. I can't tell you when it started. Thought it was an exhaust leak. so went through a bunch of exhaust work. So that is about the tick noise I'm speaking of. Speeds up with RPM in neutral and driving. Clutch pedal in or out doesn't change it. Seems louder on a cold start. 2-3 years ago I had a H55 installed. New rear Main, clutch and all the trimmings. This is were I have Located the sound. Any ideas would be appreciated.
