The most common culprit is the valve cover gasket cracking due to engine heat cycle degradation. Always apply a small dab of liquid silicone sealer (RTV) at the T-joints where the timing chain cover meets the cylinder head before installing a new rubber gasket.

Never reuse old head bolts. The manual specifies they are "Torque to Yield" (TTY) and require replacement.

Rotate the crankshaft clockwise until the timing notch on the crankshaft pulley aligns with the "0" mark on the timing chain cover.
