Oil pump problem?
This is my problem, after adding 5-qts of oil 15w-40, I start to prime the pump/block I added oil in the oil filter. I started to prime with a cordless drill and battery went dead (only happens when you want to use them), I grabed the Sears 3/8 4.0amp drill and started to prime (w/shaft primer in pump) the intake is still off so I can see. The pump was turning fine, then felt the pressure, the drill started to smoke. I set the oil pump pick-up at 1/4" from the bottem of pan. Will the oil restrictors I installed in the back of the block do this? or is my pump bad, or pickup too close to pan, or needed a thinner oil? BBC 496,solid roller cam/lifters, roller rockers. Thanks I want to make sure before I install the engine in the car, Thanks again
