Ok I have a d16a6 block with a d16z6 head on it. When i start the car, everything seems fine. When the car warms up, the oil light on the cluster comes on and sometimes "flickers". I took the oil jet out of the block for the swap..still didn't correct the problem..i really dont think it is my oil pump considering it is almost brand new. No smoke..Car runs good, just the oil light is on now. Can anyone tell me how to correct the problem...as of now i know for a fact it is not the headgasket, the bearings, might be the oil pump but as i said before i doubt it. PLEASE HELP!!!!!
