Was finishing up mowing last Friday and stopped the mower to start the grill. When I returned to the mower, it started and ran fine for about 10 minutes, then smoke started billowing out from under the hood. Ugh! Ran it only for a couple minutes more to park it, then shut it down. Opened the hood to find oil pooled on top of the engine.

This 782 has over 2900 hours on the meter. It's a K-17 series II. Before this, it would puff a very small amount of smoke on start-up, but never while running.

I haven't tore into it yet, but am thinking blown head gasket.

What would be your initial thoughts?
