Oil is transmitted to cylinder valve train rockers by oil pump from the oil pump...now i dont think the oil pump pressure is diminished unless high mileage . Most dash quages will show pressure or a mechanic can place a quage on engine ..general oil pressure at 1000 rpm is 30 to 35 psi. POOR MAINTANCE LACK OF OIL CHANGES CREATES CONTAIMINATION AND clogging from goop of old oil ...Oul gallery and oil passages are clogged or partially....take valve cover off and inspect or clean... Flush engine with a cleaner ot automatic transmission fluid let run for 20 minutes and drain . Add fresh oul and oul filter
Check the strainer on the oil pick up in the sump
Could be bad oil pump.
