Did the engine pack up or...? In the video it sounds like it's making at least some power. I hope she gets into a tank of fresh water fast or her future is gonna be a little bleak.
On a slightly similar topic, what has become of the P-47 that ditched a couple of years ago on the east coast? As I recall the pilot didn't make it out.
I doubt it - that's just how they sound when mis-firing or incorrect air/fuel ratio. Heard it many times on B-25s and TBMs, it's also partially due to the plane having two large stacks on either side, so you automatically get a "misfire" vibe even when running correctly.
I'm assuming he had it fire-walled but the engine was at low-RPM. I'm inclined to think the internals were okay, but air/fuel or fuel supply (ie carb or pumps etc) have something to do with this.
I saw an R-2600 with an unhappy carb which exhibited VERY similar behavior (like this, after a few flights prior to which she had been sitting - this bird didn't have many hours post-resto yet). They're very sensitive to being wetted every 30 days or so, not sure what Valiant's SoPs are or if the carb was rebuilt/bench-tested or not, but just thought I'd add this since I've seen it personally.
Thermal shock could be a huge issue for this engine anyways - if they can't get a good core out of it, it may be a no-go for them to restore (need a prop, electronics, eng accessories, avionics/radio stack/instruments/gyro etc etc also).
