Firstly..........calm down.
This doesn't get sorted today,sleep on it.
Are you keeping the warranty, ie getting the oil changed as part of a service? If so the dealer needs to know, other wise they will torque to spec and possibly strip whatever you end up doing? Hell, you take it in to them and explain, they may say " oh yeah we get that all the time ,we do a timesert service ,no problem"
Are you going to be happy toodling down the motorway at 85 with a "temporary" repair?
Take time and get it right ,one way or another.
Luck
