My camper is fitted with a Golf Mk1 DX engine that I think uses the vans original gear box and flywheel?
The van (i think) was a 1.6 diesel, it is watercooled.
I am trying to check timing marks but the flywheel does not have the usual TDC punch and 6 degree BTDC that Mk1 flywheels have.
Any idea how I would go about finding 6 degree BTDC, and does this picture tell me anything about the flywheel? Any info on possible gear box ( 4 speed)?

Thanks
