brus brother Posted November 1, 2004 Share Posted November 1, 2004 High pitched whine in 2000 Legacy GT Over the last 3-4 months, I have been noticing a whine which seems to come from forward of the passenger compartment. Been trying to narrow down the cause of this but the best I have been able to do is determine that it only comes on when the engine is under load/open throttle. If I'm driving on the freeway, it comes and goes as I press/release the accelerator. While on cruise control, it also comes and goes when the car is trying to accelerate uphill, etc. Am certain it does not correlate to engine speed. If I release the accelerator at 70mpg (and note that rpms stay high), the whine goes away immediately. My thoughts are that is has somehow to do with the injectors or throttle?? Any other thoughts or similar experiences? Link to comment Share on other sites More sharing options...
Setright Posted November 1, 2004 Share Posted November 1, 2004 Cant see why injectors would whine. I would suspect an intake manifold gasket leak. A small hole that causes a whistle/whine.. Whinining is usually gearbox stuff. Link to comment Share on other sites More sharing options...
brus brother Posted November 2, 2004 Author Share Posted November 2, 2004 Another Subaru website suggestion included "center diff" as a possible culprit and "learn to live with it" as a solution. If it only started recently and I am covered under a 100K warranty, I'd like to have some direction to aim SOA. Hep me puleeze! Link to comment Share on other sites More sharing options...
