Engine making clapping sound, is this normal?

ohohoh123456 · 09-11-2013, 08:42 PM

Hopefully people can hear the clapping sound in the background. My baby behaves like this when oil temp goes above 200F. Wondering if this is normal? Please help. Thank you.

Try popping the hood and making another recording. I don't hear anything abnormal but I don't hear much of anything in your vid.

do you have a different cluth or flywheel? it almost sounds like that

Stick your head under the car, pop the hood, &c and see if you can narrow down where the noise is coming from. A paper towel core or similar held to the ear can help narrow it down even further. Be careful around a running engine - there are moving parts that will hurt you.

Depress the clutch pedal. Does the noise go away?

DEpointfive0 · 09-12-2013, 01:33 AM

Is he hearing the valves?

1slow370 · 09-12-2013, 01:27 PM

doesn't sound like the valves I second the does it go away if you push the clutch test

Chuck33079 · 09-12-2013, 01:28 PM

It's either the clutch or the valvetrain/injectors/VVEL. The top end of this motor is noisy.

i can only make out the flywheel/clutch chatter, but you said its at certain temperature so.. I could be wrong

Burns should be the least of your problems, unless you get in a big hurry. You won't be grabbing and shaking things like you would when looking for a rattle. The parts that are really hot are putting off enough IR that you will feel the heat before you get too close. Clothing, jewelry, fingers, elbows, &c can easily get snatched by moving parts before you can blink an eye.
