change it soon, I noticed that my oil light would flicker on and off at idle, never really thought anything of it, drove on it for 3 days, on the 3rd night, at 1 am, the engine decided its had enough, locked up, and we had just ran from the cops at the street races, it sucked, and that ruined that bottom end, the number 2 rod was literally melted to the crankshaft by the spun rod bearing, i got it off the crank, but couldnt get the bearing pieces off the crank. Don't drive long like that. -Ben
