I agree, you definately want to have an oil pressure gauge even if it is only a stock one. It's not hard to hook up since all the wiring should already be there in the harness, you just switch out the oil press sender on the block and get some junkyard gauges from an sr5 or something. Keep an eye on the gauge and if it is gettin real low I would suspect the pump. Another thing you can do to cheat is run 20/50 to keep your pressure as high as possible till you can do the repairs.
