Oh and you might get a slight vibration from the engine being imbalanced from loss of compression in a cylinder. It will get worse as time goes on if your car has a cylinder imbalance. Unfortunately that's what happened to my FS.
That really high sharp sound where it almost sounds like an electrical arc is a valve hitting the top of the piston. You have a stuck valve, probably exhaust valve. You need a leak down test to determine which cylinder is causing is. Bad exhaust valve will cause loss of power, bad MPG, and heavy carbon monoxide smelling exhaust (possibly no visible signs though). Hope I'm right so you can at least get a shop to give you a diagnosis. Ask for a leak down test.
Ah man. Sounds like my KLZE did about 3 weeks ago before it shattered No.6 piston. It'd spun the crankshaft bearings on No.6 and it was the noise of the rod knocking against the crankshaft. It got progressively louder, at first i though it was my friction spring gear. Going to strip the engine down and perhaps stroker it. There's a video on here of a Probe GT with a spun bearing.
this is a hla that hasnt been oil filled yet. takes some time. try hla cures if it continues.
u should also replace those friciton gear springs. faulty fabricated and theres newer versions at ford n mazda

Sounds like a Valve or a broken Rod Bearing

Sounds like spark? like a cracked plug wire or something. Otherwise tbt or friction gear
