My 7mge was doing the same thing but mine more sounded like ignition timeing. Since then I have removed the motor and took a look I could find no internal damage it was a lift shim that was to far away from the cam and when you get on it the cam would rattle it. From what I heard in that video it doesnt sound like that. Completly off subject did you read the one from that civic guy ROFL because supras are mad fast. Anyways my 86.5 did that when driving it one day and it turned out to be a rod bearing took a dump because my distributor was leaking and it is kinda hard to see underneath it to see the leak. Cost me 1600 in parts to rebuild then I could have bought a 40k motor for that. It sounds like a pain but someone told me on a 7m you could pull the pan in car and check the bearings. I know on a 1JZ it has a two peice oil pan so I know you can on it. Try to get the pan off if the valve cover thing doesnt pay off. Look for metal in the pan and look at the bearings to see there is any bad wear.
