Hi list, I am new to the list {and = vanagons as well} this is truly a wonderful resource of information. I think that my = 85 Westy might have a main seal leak, the area around the trans. {where the = differential and the motor meet} is wet with oil. It is hard to tell how = much is oil, as the trans. pan is seeping as well and blowing back as we drive. = I am replacing the trans. pan gasket today, which should give me a better = idea of what I am looking at {main seal wise}   Anyway my question is, = if the main is only leaking a small amount, how long could I put off replacing = the seal? we are leaving for vacation in a couple of weeks, and I don't have = the time to do repairs before we go. It is a fairly short trip of 500 or so miles.  Any thoughts?  thanks for all tips and help from the list.    Alan   85 Westy           &n= bsp;           &nb= sp;           &nbs= p;            = ;            =             &= nbsp;           &n= bsp;           &nb= sp;           &nbs= p;            = ;            =             &= nbsp;           &n= bsp;           &nb= sp;           &nbs= p;            = ;
