Van starts fine and oil light go,s out. Get to next job start van and oil light stops on. Turn engine off wait a second restart and oil light go,s out? Oil level is full and van was serviced in January. Been happening on and off for a couple off weeks.
I have had this problem twice now and both times it was a broken cam belt guide pulley leading to the oil pump pulley breaking off. The first time this happened I was lucky and the engine was ok. I dont know the outcome this time yet as it only happened last night.
