All, I had this seal replaced under warranty at 3k miles it has failed again at 33k, This is a 1k$ repair. I am very motivated to do this myself any thoughts?

It is much easier with a few special tools that will cost much less than the labor charge you quote. At 33,000 miles I would be tempted to put in a new clutch plate even though it should be good for many more miles, and also replace all the seals in the gear box while it is accessible. I'd also make a close inspection of the crank and all around to see what may have caused the rear main to fail.
 
This is not a common problem on '12+ Stelvios. Let us know if it's the crank oil seal or paper flange gasket. I would replace every seal, gasket and o-ring while it's apart.

Yes I good idea and I will take this advice. Any thoughts on the easiest procedure to drop this engine?

Well it seems like I had the lucky Guzzi. To tell the truth when I dropped it off at the dealer I wanted the bike replaced with another. Since the seal failed at 3k miles I was fearful (and it has) it would fail again at 33k. Moto Guzzi refused and very grudgingly warrantied the repair. The dealer (great guys) provided a loaner to ride home...and you might not believe this but the loaner Stelvio 2010 seal failed on the way home coating the rear tire! What luck! The dealer sent a truck to pick up the bike! I have purchased 4 Guzzis from this dealer ( no complaint with them) but I am totally unhappy with Moto Guzzi support of the product the manufacture.

I haven't dropped one out of the newer CARC bikes yet, but it is probably like the Spine frame bikes. You can either drop the engine out, or drop the gearbox. In either case it requires disconnecting just about everything from the engine, Air box, throttle bodies, phase sensor, and all connections. The workshop manual in the downloads section will give you the procedure.
