Installation
Before installing the camshafts, I would advise setting the crankshaft at approx 45° before the TDC marker. This will drop the pistons down in No.1 and No.4 cylinders and ensure there is no unwanted piston to valve contact when the camshafts are rotated without the timing belt installed. Once your confident that the timing marks on the inside of the cam gears are aligned, you can then rotate the crankshaft clockwise to line up it's TDC marker before installing the timing belt.
