One more issue. Has anyone ever had the oil pump sieze up?? I bought an '03 with a blown engine. I was ready to put it back together and decided to pull the oil pump to inspect and clean it. The pump was trashed. The larger outer rotor was broken along with the pin and inner rotor. I figure when the bearings and gears started flying that a piece got in and jammed it. I now have a used pump but the outer rotor doesn't want to drop into the case easily, there is signs of something being stuck in the case or that the old pump seized. I have been trying to clean it out with emry paper ect. I guess my question is how hard should the rotor fit into the case and will i hurt anything by using emry cloth on the case??
