Valve Timing Verification

CAUTION: Painted or colored chain links are used during initial engine assembly and can not be relied upon for valve timing verification. These markings are in different locations for early production, late production and service parts. Only use TDC marks, cylinder head cover sealing surface and camshaft sprocket marks to verify valve timing or engine damage may result.
