I got the old seal out and removed the 4 bolts, but the ring that the 4 bolts hold wouldnt come out. I ended up just replacing the seal on it... Is it okay to just keep that old semi circle gasket and re tighten the bolts?

 

thats cause its held in place by the oil pan the back 2 studs that hold the oil pan on go into that ring

 

You don't want to take off the seal holder. Just pull the old seal out and tap a new one back in and you're done.

 

yep you went to far....

 

Since it never actually came off I can just screw those 4 bolts in and it wont leak right? Im changing the oil pan gasket as well...

 

You should be good to go.

 

The oil-pan gasket kit should come with a gasket that is for the aluminum piece, so you can change it if you take the pan off.
