Grinding noise coming from engine - sound clip
 

Hi 986 Experts,


Please pepper my situation with your wisdom...

2001 Boxster S
118,000 Kms
last service: 105,000 kms
minor mods e.g. pod filter and cold air intake
IMS LN Engineering double row bearing 1 year ago


A grinding noise started coming from the engine bay this morning while parking the car (warm engine, low rpm)

I turned the car off just after it happened hoping it was nothing


I came back 8 hours later, started the car and the noise was there from the start (recording is from inside)

The noise changes sometimes (in a bad way), it gets higher pitched for a few rotations then goes back to normal, so maybe its a bearing.

No noticeable change when I turn on the AC



Please share the love if you can
