Engine smoking and burning lots of oil - anyone pulled an engine?

[wcntech]

Hello!

I have a friend who has a 2015 Spyder RT-S SM6 with about 20k miles. He was on a ride and did not notice any changes in power or responsiveness of the engine, but they stopped to eat and when they came out and started it back up, it was smoking really bad, especially at start up. There is still not any noticeable loss in power, it just uses oil at about a quart every 90-100 miles. Dealership suspects maybe one piston with a broken ring.

My question is, has anyone pulled the engine on their RT and if this job is covered in the service manual? Or would you take it to a dealer? Anyone else have or hear of this problem?

Thanks!
Andy
