Just as a general point of reference, will coolant in your oil cause the pressure to drop in the oil system? I replaced the radiator in my blazer, which was causing coolant to get in the oil, but I also lost pressure in the oil system, which I assumed was a bad oil pump, but now that the radiator is fixed, the pressure seems to be ok (at least for a while). Should I go ahead and replace the oil pump anyway?
