1991 Toyota Pickup 4wd 5spd 4 cylinder 22RE with no oil pressure
Replaced timing chain, timing chain cover, water pump & oil pump. Truck runs but there is no oil pressure.
Did a manual check for oil at pressure sensor bung & oil filter & no oil is flowing. Have since packed oil pump & pressure was restored. Turned vehicle off to put drive belts back on & restarted vehicle with no oil pressure again.
Have repacked pump, changed oil, filter & replaced new oil pump with another new oil pump. Checked passages for blockage & seemingly clear. Oil runs freely when poured through via funnel.
have the same problem?
