I think my theory about the VVT solenoids could be the reason, but whatever,
You did not just add MMO. You bought a sludged engine and...changed the oil. That was step one in de-sludging. You then changed the oil again; step two of de-sludging an engine. MMO is simply along for the ride. No one reading this or your previous threads should focus on MMO as the main contributor here, but the fact that simply changing the oil and continuing with a prudent OCI is key to slowly and efficiently cleaning a sludged engine.
Your theory about VVT actuation is very plausible.
