So I have an 09 WRX, Perrin intake stage 1, I noticed the other day a small squeaking sound coming from what I believe is my turbo. Car runs, drives and operates just fine but when at idle the car just goes, squeak...... squeak...... squeak as the engine is turning over.
Possible bearing problem?
The car has 38000kms and is driven but never abused. The temperature here is -8c. I did have a small issue the other day where one of my intercooler bolts had undone itself and was finger tight. I tightened it back up and the car seems ok.
