The oil pumps primary purpose is to circulate engine oil under pressure to the bearings, pistons and the camshaft. This lubricates these systems, allows the use of higher-capacity fluid bearings and also assists in engine cooling.
This is a valve guide for the Isuzu FMV and FTR model truck. A valve guide is a cylindrical piece of metal, pressed or integrally cast into the cylinder head, with the valve reciprocating inside it. Guides also serve to conduct heat from the combustion process out from the exhaust valve and into the cylinder head where it may be taken up by the cooling system.
This is an e valve for the Isuzu FVM and FTR model trucks.
