oil pan gasket ??

hello every one,,,i've been finding quite alot of oil under my 95' aurora..it looks like it's comming from the oil pan gasket..has anyone replaced the oil pan gasket on your aurora?? is this a huge job?? i've seen some of the other posts for oil leaks,but looking for more info on changing oil pan gasket..all responses are appreciated...thanks

my aurora used to leak oil but it just stoped...seems like i go through a lot of oil though...

well what i have heard is that you need to remove the engine to replace it but you can check the bolts to see it they have come loose and then just tighten them, but it it is tight dont tighten any more cuase you can strip it out then that will cause more probs, they need to be just snug
