Remove valve cover.
Turn the engine by hand (see previous section) until both are right (in the direction of travel) camshaft lobes will not point upwards.
For greater accuracy, turn the crankshaft until the mark on the flywheel is exactly opposite the vertical arrow in the viewing window at the clutch housing (see fig.). This way you can find the exact location of the top dead center of the first cylinder.
Pistons in cylinders 1 and 4 are in their highest position (at top dead center), when notch (2) on the flywheel precisely opposes the vertical arrow (1) in the inspection window of the clutch housing. First, completely unscrew the cover.
