Honda Acura NSX 1991 Service Manual page 56

The lubrication system is a full filtration circulation type. The oil pump is directly linked to the crankshaft; oil to the oil
pump is pulled through the oil strainer, after which pressure is regulated by the pump relief valve. It is then filtered
through the oil filter and pumped to the cylinder block and cylinder head. A baffle plate is provided inside the oil pan; the
baffle plate helps minimize the changes in oil level produced inside the pan while driving will affect the amount of oil go-
ing to the pump.
