it is a mechanical pump. I did not check the main's while I had it apart. I didn't even remove the motor from the truck. Are the main bearings someting that I can replace fairly easily like by just removing oil pan? Also, i did not replace the oil pump.
also....when i remove the rocker arm covers, I do get our coming out of there if thats any help
