@ dreams Yes, definite clunking from block region as distinct from whirring sound from camshaft at top of motor. Initially the noise comes and goes then its there all the time. When Honda dealer took motor out of car to fix the problem they found the cylinder bores so badly worn they could not re-bore and fit maximum oversize pistons available hence the need for brand new short motor. When I went to pick up the car after new motor fitted the dealer advised another Jazz owner came in with exact same problem. There is obviously a major problem with Thai built motors that Honda and motoring press are not talking about.
@ bennjamin The second NEW MOTOR is showing the same problem. So Honda Australia have a supply of" lemons" just ready to install in my car?
