Any suggestion on the cause of "clacking" from my exhaust
, I think it is from the exhaust
. See video link below.
The video sound is not perfect the sound is a definite clack. Sounds like a leak in the exhaust. The normal exhaust outlet sounds normal and plenty of water
flowing and with the lids closed it is not particularly noticeable. The engine
was recently lifted for new mounts and oil seals
is a Westerbeke
3B30 and this makes it sound like an old tractor engine, which it is
Sprayed everywhere with soap water
- no obvious leaks
Replaced the top hose (engine to box)
Removed the water box and pressure tested it. No leaks
. Not a high pressure test just a standard bike pump
with rubber seal and hand blocking the outlet. The box is simple just an empty box with an inlet pipe and an outlet pipe at the top that extends 75% towards the bottom. Hard to imagine anything to fail.
Rubbed the box to exhaust outlet hose with soapy water no obvious leak and no change in sound (like going over a weak area).
Poking around covering things etc produces no change in sound.
out of gear
makes no difference.
Any suggestions welcome:
