Thanks for the response. Yes, that was the first time i started it. I hurried up and tured it off after I heard that. I don't know if I should have let it run. There is no preassure gage on the C220 so I am not sure of the oil preassure. Being that the car was fine until I changed it, I am assuming that is the problem.

Let me know what else you think.

Thanks a lot,
Ryan
