I am stalling to replace a rusty oil pan in my 2004 Grand Prix. I have already purchased a new oil pan plus gasket. I looked underneath the car a few weeks ago, it looks simple enough, however a portion of the front end of the oil pan is hidden behind a cross bar. As a sophomore handyman, am I biting off more than I can chew or should I take it to my local mechanic so he can smack me with a few hundred $.
