Porsche Boxster 986 engine strange noise

[Trewis15]

I am from Slovakia , I do not speak English well . You know someone help me ?


I changed things marked on the photo. The sound is still not changed , it is the same .


From as many starting , I discharged battery . At the start I can fix it the same sound (in 00:15).

You might try removing the belt to see if the noise goes away with belt removed. It's ok to run a few minutes with no belt. However from that last video with the battery discharged, I would check the spark plugs. A loose plug can make a chirp like that.

I had the same sound and 911 monty is correct it was a loose plug that had not been tightened correctly.

Just an FYI. New plug torque is 30nm/22ft lbs. Used plugs retorque to 25nm/19 ft lbs. Cold.

OH and Welcome!

I kinda liked the "ragged candle" translation, had a chuckle over that one! Well worth the price of admission. Enjoy!
