Whistle

[SilverFox06]

Am I supposed to hear the engine when idling? I had a bunch of work done, i.e., elbow intake, intake actuator, oil change, micro filter, air cabin filter, oil filter, thermostat, coolant flush. Runs wonderful now and much more quieter than when I purchased it used four months ago, Sounds like a buzzing from the tail pipes while cold idling and once warmed in the front somplace -- sounds like a tape is caught in the fan sound. I checked the fan -- it is fine. What is that? Views anyone????

belt tensioners might be on their way. best way to check is to remove and spin

[SilverFox06]

What's the cost? I have 77k - is it time to replace?

Hey, the Bimmer shimmers/buzz-like when idled/stop light when the air conditioning is on. Please help?

[SilverFox06]

How much for the tensioners?

[SilverFox06]

$90 for the air conditioning belt tenioner.

yes having the cracked elbow intake tube has hurt my gas mileage BIG TIME. But how do i know i need to replace the DISA valve? Do i assume if the elbow intake valve is bad that the DISA is shot? thats 240 bucks i really am not looking to spend but will if i have to.

car seems smooth ride now, just the cracked elbow tube which i'll replace as soon as i get it.

Yes, the ride will be smooth, but sluggish -- watch the RPM's. The ride will be much, much smoother -- not saying you need it. Watch your gas mileage still -- that will tell you. The part costs $170 on-line. And it takes 10 mins to install, literally. My mech. charged me $40 to install it -- that's how simple it is. Watch it over your next fill ups or if it is pulling like something is stuck in the engine -- it's needed. If not, it will go soon. They work together!

Thanks, if you can provide me with a link to the valve for $170 that will be great. if you are saying they work together then it just might be a matter of time. I have had that whistling noise for months now but didn't mind it much because the sound it was making was cool, lol

It was only this weekend when my gas went down big time that I decided to read on here and check it, sure enough it was cracked big time.

Hope nothing else went bad.
