Hey 04 Sport, Your say the Gen 1 LS has oil pump issues, not to long ago I bottomed out my 2000 and lost all the oil only a half oil filter left in the motor. It ran great just like normal and sitting at a stop light it just shut down , no knocking , pings or even a grind,. I didn't seize the motor it did fire up again but she was not happy at all. I replaced the pan,oil,filter . I pulled the plugs and put a spoonful of " Motor Honey" down each cylinder and fired it again. ( That really fowled the plugs ) so I also replaced them. With the pan down I found my passenger side tensioner had come apart so I'm in the middle of replacing both sides. So anyways I'm asking , Do you think my oil pump may be gone also? The car is a 2000 LS base 3.9 V8 with 127,000 miles and they are all hiway miles and taken care of miles,
