Cylinder head onto the gasket Cylinder head bolts lubricated with clean engine oil Tighten the bolts in sequence in 3 steps to 40 ft. lbs.


NOTE If any bolt does not meet the torque, replace it.


Mark the forward edge of each bolt with paint, then tighten each bolt, in proper sequence, an additional 90 degrees. Check that each painted mark is now at a 90 degrees angle to the front

Remaining 8mm bolts, lubricated with engine oil. Tighten both bolts to 13 ft. lbs.
