I did an oil change about 3 weeks ago. There is no oil on the ground, so I can assume the oil leaks when in motion. I have a lift here, however it has a car on it, so tomorrow I'm going to drain the oil. And fill it back up. Should I pull the filter too and see if there is anything in the filter? i dont know what might be causing it, so tomorrow I'm pulling the turboback off and putting it to stock just in case it has to go in ... wait a minute, of course it has to go in! I know the TBE didnt cause the leak but we all know how anal car companies have been getting ... well, my oil pump went on my TA and then it came back on a few days later and they wouldnt check it. A few weeks later, it went and the engine was toast ... replaced the motor under warranty, brand new LS1. I think i might invest in the warranty extension.
