The structural camshaft carrier is cast from aluminum alloy using a high pressure die cast process. The camshaft carrier is located on 2 dowel pins in the cylinder head and secured with bolts. A gasket seals the camshaft carrier to the cylinder head.
The primary function of the camshaft carrier is to house and secure the intake and exhaust camshafts. The camshaft carrier bore geometry is bored in a single machining operation to make sure optimum friction reduction. Each camshaft cap is uniquely identified and must be matched to its related bore.
The camshaft carrier also provides locations for the CMP , the oil filler pipe and the engine vent oil separator. The camshaft carrier has high pressure oil bores feeding the hydraulic VCT actuators and provides thrust face lubrication. A low pressure oil gallery returns oil from the engine vent oil separator, back to the cylinder block and the oil pan.
