I just bought a 97 lesabre cutom wth leather and all but a sunroof..I notice some oil leakage from the topfront of the motor so it seems to be the valve cover my bro says thats what it is was just wondering how easy this job was he works on car alot and i know he can do it but is it any different from other cars like things ied have to remove or what ever to get to it thanks in advance

It's a common problem. Back one is tough to get at.
