Either I or the previous owner has done a stoopid thing, but the timing on my project's engine is lost. This is a normally aspirated Transit engine from the late eighties. I can find the locking holes easily enough in the camshaft pulley and the fuel pump pulley, but there seem to be 4 different ones in the flywheel. By poking a screwdriver through the locking hole and turning the engine by hand, I can "feel" two larger holes about 180° apart and two smaller ones a few degrees away from the bigger ones.
So what do I do now?
I'm assuming I'll need to remove number 1 injector (there are no glow plugs) and find TDC, but how does that relate to the point where the engine is meant to be locked for changing the timing belt? (No, I haven't got a manual.)
Any positive suggestions gratefully received...
