Recently I fully rebuilt my 200 engine which runs as sweet as. No smoke whatsoever or leaks which is surprising. However I have a fairly loud tapping noise which appears to be coming from centre, lower front of the engine.
Myself and a landy builder have had the stethoscope on trying to locate it but no obvious location.
The strange thing is it doesn't start straight away on start up when cold, takes about 5 mins to materialise. The sound appears to be half engine speed (t-belt/cam speed) not full crank speed.
What is even more strange is that when I drive on an incline the noise stops, go back on the flat and it's back. I have disconnected all ancillaries including the viscous fan. No change. After some research I was inclined to think the timing belt tensioner pully may have been at fault so I spent yesterday stripping down and replacing it. Timed it up and ran it without front cover for a few mins and the noise wasn't evident but as I said it wasn't ran for long.
I am now down to brain matter after scratching my head over this so new ideas are very much welcomed and needed.
