thanks for the input guys, i'm really confused as to why some have washers. Some of the bolts that went into the front cover werent even torqued all the way down, one was cross threaded but only finger tight. It's amazing my pan wasnt leaking a significant amount of oil (just enough to keep a droplet on the bottom of the pan ready to fall). I don't know what whoever did this was thinking.

The bolts that go into the front cover are soo easy to strip. I havent owned

a seven yet that didnt need to have them/it fixed.
