yep definitely check that those relief holes are spitting water after it warms up. with the IR gun, blip the throttle in neutral. you should see the temp sharply decrease. if you dont you know you have a restriction in the water tube grommet or exhaust seals as i mentioned (if theres no crack in the block or something but can easily check the plugs after a high speed shutdown to see if they are steam-cleaned).Nope, runs perfectly fine at idle. It's not until I start accelerating past, say, 2000/2500 RPMs or so that the high-pitch ringing sound starts. It was very faint this time, almost inaudible. Changing the water pump seems to have helped a lot. It only overheats when under load at speed.
