Well, in my more optimistic opinion,

You could certainly try to retorque them, maybe you could be the first or one of the first to be able to put it off until later.

You have the straight 6 M104 engine right? I think that many memebers here with that engine expect the M104 gasket to break at a certain mileage. So it could be that it is just due now and that there is not much to do but get the proper job done.
