Hello all,
Ok so, on Wednesday I picked up a 1997 V3 STI. It is an imported Type R(2Door) with the DCCD gearbox.

Problem. The car is making a deep wine sound whilst driving normally at around 3-4500 revs! this happens on half throttle and as you ease of the throttle is goes quieter until the revs are down around the 3k mark then stops(if you come straight of the throttle it stops straight away) It doesn't happen on full throttle when accelerating hard. Only when crusing around 60MPH.
Sorry to join the Forum and ask a question, but a bit worried!
Has anybody had this befor cos to me it sounds like a diff problem, I was told that they can make a noise when locked and driving the car slow but it's open(first green light) and it's while driving in a straight line!!

Cool Forum as well though. I intend wasting many working hours on here.

Is it a kind of red or white wine noise?

More seriously, the whining sounds like it might be the bearings in the box. The noise dccd boxes make is more a clunking / grabbing sensation when the box has lock on it and you are manouevring slowly, as you were told.
Alternatively, you can sometimes get a kind of "clangers" whistling/hooting noise if the wastegate isn't shutting properly and the cure for that can be pulling the pipes off the boost control solenoid, mounted on the offside strut turret and spraying carb cleaner inside.

Might be best driving to somewhere like Subaru4you in Reading and getting them to look at it though.

Best of luck

"Is it a kind of red or white wine noise? "

LOL!!

Thing is if it was gearbox or diff related it would do it all the time and/or get worse but it doesn't. Only does it at 50-70MPH and at 3-4500RPM. I took the guy from the import center who said it was more of a whoosh(??) and he didn't think it was a problen bit if any body knows a good specialist around the Gatwick/Surrey area I would like it looked at!!

Thanks for the response fat boy I might look at the boost control solenoid!

My car has started doing this lately too. I think it's drivetrain related - almost sounds like the Prop as it seems to be coming from the back end of the box.

Seems to do it when I go round corners slowly which then leads me to think it might be the rear diff but not sure.

My car is also a Type R but a V4 if that helps narrow down the problem.

Does the noise stop if you dip the clutch ?????? , i have a simmilar whine and i think its to do with the power steering as its louder when you turn the wheel.

 

i have a simular prob. when still clutch up it makes a wineing clutch down it goes, thought it was release bearing had clutch done and it still doing it, it starts to whine as i pull awayand carries on at the same volume till i slow rite down.. cant work it out
