I just purchased this car, original owner 105,000 miles. Garage kept. Need to replace the oil pan gasket. I want to do this myself, watched youtube on how to...the gaskets I've seen are 3-sided rectangle. It's not a continuous piece? This seems odd to me, any words of wisdom or recommendations on this repair? Is a torque wrench required?

 

I did this on my convertible about 10 years ago. Yes, it's a "U" shaped gasket. A torque wrench is not "required" but useful when re-assembling. You'll need to remove the "Y-pipe" to get in there. Here's a how-to for that part of the job:

You might want to invest in a shop manual like a Haynes or Chilton's.

All-in-all, it wasn't a terribly difficult job.
