Tighten the cylinder head bolts. Tighten the cylinder head bolts is sequence to 29 Nm (3.0 kgf-m, 22 ft. lbs.). Use a beam-type torque wrench. When using a preset type torque wrench, be sure to tighten slowly and do not overtighten. If a bolt makes any noise while you are torquing it, loosen the bolt and retighten it. Make sure the threads are clean, new heads bolts are best.
