Help Identify This Strange Noise Please

Hi Steve, Well done for spotting the problem. You do however, seem to have an exhaust leak. Get a 3 foot length of garden hose and put one end to your ear and then poke the other end all over the manifold pipes etc. I am sure you will find a leakage in that area.

Thanks Alan, I?ll do just that. Can I ask what it was you heard to raise your suspicion?

Best

Hi Steve, It's just a very distinctive noise I have heard a thousand times of an exhaust leakage from one or more of the pipes or flange gaskets. Not a major leakage, just enough to be heard. Should be easily located with the hose test.

Update: Turns out the noise was actually from my clutch adjustment nuts which had come loose.
