Before the piston and connecting rod assemblies go in the bore, first install the piston rings. Cover the piston and the rings with clean engine oil and after that, use a ring compressor over them, tightening it so the rings stay motionless. Lay the bearing onto the connecting rod so that the hole through its middle matches the connecting rod's hole, then give the surface a light coating of clean engine oil. Screw the Special Tool 8507 connecting rod guides into the holes of the connecting rod bolts. The "F" mark on the piston pin bore surface indicates where the piston goes, so both cylinder banks should have this raised mark facing forward with the connecting rod's oil slinger also facing that way. Completely wipe the inside of the cylinder and spray it with engine oil. Into place the crankshaft until the center of the cylinder bore, then insert both the rod and piston while aiming the rod guides over the crankshaft's journal. Push down on the piston's head while stepping the connecting rod in place on the journal. Because they are Torque to Yield Bolts, Connecting Rod Bolts must be replaced each time they are removed or loosened. Apply engine oil to the bolts and the bearing surfaces, drop the connecting rod cap and bearing into position and tighten the bolts to 27 Nm (20 ft. lbs.) plus 90°. Fit the cylinder heads, timing chain, cover, oil pan with gasket/windage tray and head covers. Add the proper engine oil to the crankcase and connect the negative cable to the battery after you have done that.
