There are holes in the bores for the main bearings, between the cylinders for piston cooling orifices. These holes must have orifices or plugs installed or low oil pressure will be the result.
If the base for the oil cooler is 357.2 mm (14.06 in) long the engine has piston cooling orifices installed. If the base for the oil cooler is 268.2 mm (10.56 in) long the engine has plugs installed.Piston cooling orifices were eliminated from 3208 truck engines effective with truck engine 2Z30692 with a rating of 150 KW (200 hp) @ 2000 rpm or 160 KW (215 hp) @ 2200 rpm.
