[dumb yet serious question] how damaging would this technique be with alcohol?

Well that’s a fun question! Hm... I’m assuming that the damage has already been done, otherwise they wouldn’t have record ed this.

It doesn’t look like the technique itself has damaged anything quite yet? But they just created a whole lot of extra work for themselves if they have any intention of getting that engine running again.

Aside from the obvious potential for hydrolocking, I’m pretty sure alcohol is bad for rubber hoses. However, most of the vacuum tubing is already out of the way, along with the intake manifold. So there’s not much rubber for it to saturate, except for maybe the lower radiator hose.

I would use ammonia because I'm basic

Unless you went for seriously long exposure, the hoses would likely be fine with alcohol. You’d probably want to blow the lines out, pull the spark plugs, change the oil, crank it over a few times to clear the cylinders, then put the plugs back in. Should be fine after that.
