You've checked coolant level to confirm that you're burning it up?

if you are smoking around 4 grand, then you have one of two problems:

A: bad rotor oil seals or...
B: blown inner coolant seal on 1 of the rotor housings which will need a rebuild.....sorry to say but it sounds like you need a rebuild anyway!

or he could rebuild it and minimize the damage.

Pull the radiator cap off on a cold engine and start it up. Let it run. If the coolant starts bubbling you have a leak. Does it smell like coolant when you start it up? Coolant would be draining into the combustion chamber while it sat overnight. I had to rebuild due to a coolant seal.

you could also get it nice and warm and let it cool without taking the radiator cap off, and pull the plugs and look for coolant on them. The system will build up pressure( likely more then normal) which will help force a good bit into the housings and on to the plugs.
Driving MY old GSL-SE FB today for the last time with blown coolant seals, it's got more space for my 10th AE rebuilt engine(coolant seals) then my vert(whos got 16k on a new engine(had failed coolant seals)).
