Hey All, usually an IO guy so I apologize in advance. 2001 OX66 200 saltwater series II FI.
To me it sounds like a standard pinging noise coming from cylinder 1.
Apparently the motor had an oiling issue prior that was resolved. Good compression on all cylinders. I did find he had hot plugs in it (BR7HS vs BR8 or 9).
When the plug wire is pulled from cylinder 1 noise goes away. Comes back as soon as plug wire is reconnected. Was thinking an oiling issue to that 1 cylinder or a bad injector? Someone had mentioned a top main bearing as well. Any insight?
