I changed mine at 188K diy and it wasn't overly hard, just tedious. I have pix on this site if you search. Get the rubber grommets along with the gasket when you do it if you DIY.

The fun one is the $5 oil canister gasket that fits between the Oil filter housing and the block. You have to take about 1/2 the motor apart to get to it. BTW, it will go bad sooner or later.......while you're on the topic of oil leaks check our your oil separator, particularly the one to the dipstick.....
you ain't seen nothing like losing a qt of oil a week!
