I’m assuming the guy on the right’s engine is extremely worn in order for valve float to be occurring and that is very much Not A Good Thing (will lead to engine damage once a piston contacts a valve)
So basically they’re beating the new car guy in an old worn shitbox
valve float can happen for all sorts of reasons; revving too high, bad lubrication, cam geometry, wrong springs… but if it has float now and didn’t before then yeah it’s definitely wear.
