noise from engine compartment


Recommended Posts

My 987s has 7500 miles on it. Particularly when the engine is cold, there is a momentary vibrational buzz from the engine compartment as the rpm passes through 2100 rpm, either at 'trailing' throttle or when decelerating. Has anyone else experienced this problem and know what is causing it? The noise seems to be from an accessory or fitting rather than internal to the engine.

Yes sir,

I had the exact same problem on my '06 987, 4000 miles. I recently posted the same question

http://www.renntech.org/forums/index.php?showtopic=11951

The issue is addressed in TSB 1726 "Screeching Noise From The Engine During Warm-up". I went to the dealer and they replaced the control piston in the oil pump with a new/modified part. Problem solved..

Thank you, everyone, for the rapid replies. This is a new problem for me, but I did not realise that it was an old topic. The car is due for the 2 year service soon ( within the warranty period) so I will be able to quote the ENU1726 TSB at them and get it fixed!

Now, another thing..........does your 987 feel and sound as if you are driving over bricks during full steering lock, low-speed turns?

Its the Ackerman steering. The wheel on the inside of the turn will lean and turn in more than the other side meaning you get this jumpy movement at the particular tyre. More pronounced when reversing and akin to driving on compacted snow.

Its all normal.
