Need some help.
On my '94 318i
When I release the gas and just coast is when it gets really loud. Also, you can hear a loud hissing sound as if there is a vacuum leak of some sort. I pretty sure it is a crankcase vent valve, but do not know how to change it! (Nothing in Bentlys about this) Does anyone have any DIY articles or simple instructions on how to replace it or any suggestions! Any help would be greatly appreciated. I want to see if I can do this myself. Thanks
Steve
