When I start the car it does not make that rattling noise, but if I drive the car and exceeds 3000 rpm's it makes that rattling noise. At first that I did not know was that the blockage of the water flowing back to the water bottle and it caused the engine to overheat and the water was dripping somewhere from the engine, but I do not know where.

Hey QLEIBY,

Is the engine overheating because that would make the engine ping and rattle at higher RPM, s I have to ask because of the coolant leak.

Please let us know what you find so it will help others.

Best, Ken

At 1st.I found out that the water line that circulates back to the waterbottle was totally blocked therefor what I think caused the motor to overheat. But now I fixed the blockage and still I hear that sound. Can it maybe be a bearing knock. Or maybe something else?

Sounds are difficult to fix over the web unless we have a video. Can you post one to youtube and then give me the link?
