I second the motion...unfortunately. The rear leak can be rear main seal, but actually most likely is a valve cover leak which also BTW is a boost leak...your car sounds right where mine was before the passenger turbo seized, and I had boost/vacuum issues up the bootay.
Hopefully you can avoid a full engine service/turbo replacement, I couldn't...
