- Measure cylinder head warpage, measure at several points along gasket surface using straight edge and feeler gauge. see scheme 91
- If warpage exceeds specification, machine cylinder head. See «CYLINDER HEAD»(ref-147486-S25493106472002091600000) table under ENGINE SPECIFICATIONS. If machining causes cylinder head height to be less than specification, replace cylinder head. When checking dimensions for cylinder head height, measure at (A) through the holes for the head bolts. see scheme 92
