We bought the van in February, it went in for a service and mot last week, the garage changed the filters and did an
oil change, they checked the coolant and garage said that it was fine., Oh and it does appear to be smoke. we do know that the last owner had cooling system overhaul in August last ...

No, we don't use veggie oil, just diesel.

Hi, turned it over, still has heavy tapping noise and clouds of smoke.

Hi Teenmal, its a 1997 2.5 Turbo Diesel.

HELP!!!!! I was reversing the Bongo when a tap tap tapping noise came from the engine, and smoke came from the exhaust, any ideas, please
