Piston Slap is hard to tell from Rod Knock even in person, let alone on a video...
Piston Slap should get quieter as the engine warms (metal expands).
Rod Knock will get louder as the engine warms and the oil thins.
+1 on the gauge--driving an old Volvo (or any car) in So Cal in the summer without a functioning temp gauge is way too risky.
