Hey anyone else have this supercharge-esque whine coming from the engine as it revs on the E30 325's? I know they're not supercharged but my car has a whine that sounds similar to it. Anyone else have it?

Do you have the wheel slightly turned? Does it whine when you're accelerating out of a turn till like half revs in that gear?

Sounds like a power steering pump -- same problem we have in our van.

Is it at all like a whistle? Do you have an aftermarket air intake? It could be from that...or maybe there is something wrong with your current air intake.

Just the regular FRAM brand one. Yeah it's more like a whistle... I've had it since I got the car. The mechanic told me it was a quirk of the car.... but I've never heard it on any other BMWs...

It doesn't effect the car's driving, but I just wanted to know if anyone else had the noise.[thumb]

It really is probably just the sound of the air intake...some air intakes whistle like that. I guess if you're mechanic says it's okay, then you're fine.

I don't have a sound like that, but my transmission makes a whining noise. I wouldn't worry about the noise in your car if it's running fine - it probably is just a quirk of your car.

I also used to have that whine when my engine was standard, but since I have modded it it doesn't do that, I always thought it was the sound the engine made, but since I changed the engine it doesn't do it anymore. Mine only used to do it in first gear.

Its the gearbox simple as that. drive any oldish car without much sound deadening and you'll hear it. (classic mini is prime example) nothing to worry about. mine does it in 1st - 3rd also then the engine/wind/exhaust[:D] noise is too much. its not usually too loud and my intake usually drowns it out. you will have a little intake noise with the standard filter (remembering it may be standard but its still 2.5litres[;)] ) its just a combination of quirky noises that signifies your in a real car rather than a Lux 'o' Barge *Cough*Mercades*Cough*[:D]

Yeah, its just the wines out of the gearbox, its just the way they sound. All BMW's have it, you just hear it more in the E30's because there is less sound insulation. Mine makes the same sound, and it also sets it apart from others, it sounds cool, lol

As for the clicking it is the rockers hitting the top of your valves, because it is an overhead cam, and there are no lifters, there has to be clearences, and when it starts clicking you are able to adjust it, all u need are some feeler gaudges and a paper clip and a 10mm wrench. You adjust the little eccentric cams on the rockers. If you dont know what you doing tough dont try it, bucause u can get floating valves, and you can burn them too. It shows how to do it in the bently repair manual.
