RomanC Posted October 25, 2011 Share Posted October 25, 2011 Each time I start the car on a cold (below 60F) morning when there is a lot of moisture, the is a fluttering sound that comes from the turbo area. The more moisture there is the air, the noise is louder and lasts longer. I am curious if others have seen this on good turbos, or if it is a sign of impending turbo death.

Dragoeth Posted November 4, 2011 Share Posted November 4, 2011 You know I'm having the same problem cept its at all temperatures. Once RPM's pass around 4k if I'm under medium throttle or more the turbo starts to make a fluttering noise thats rather audible. Just started to happen a couple days ago. And I just got the turbo replaced with a new stock 2000 miles ago and the clutch replaced 1000 miles ago. If its an exhaust leak like stated above how would I go about fixing that?

BAC5.2 Posted November 4, 2011 Share Posted November 4, 2011 What do you mean, "how do I go about fixing that"? You stop the leak. Replace a gasket, make sure things are tight, or take it somewhere to get it fixed. Why was your turbo replaced?

Dragoeth Posted November 4, 2011 Share Posted November 4, 2011 Turbo was replaced because the original blew due to no oil being fed into it 5 days after I bought the car. Clutch replacement was done due to blown throw out bearing. Edit: And a note on that, they replaced gaskets, banjo bolts, and oil lines when they replaced the turbo.

bmx045 Posted November 7, 2011 Share Posted November 7, 2011 cool, now listen for weird noises coming from the engine. blown turbos mean the oil was contaminated with turbo bearing material and it circulates around the engine taking rod and main bearings out with it time will tell to see if you sustained any damage.

Moderators BarManBean Posted November 7, 2011 Moderators Share Posted November 7, 2011 FWIW, I've now owned an '09 and an '05. Both made noises similar to what you are describing--very light 'fluttering' noise on cold start up, and only when accelerating. Goes away once the cars heated up a bit, and doesn't bother me anymore--I'm assuming it's par for the course and chalking it up to typical subaru noises.
