[GT1281]

Yesterday a friend and I installed my cp-e bov. For some reason I have a weird noise when traveling at normal speeds. Like a grumbling noise. Sounds like its coming from the center of the engine. We checked over everything and it is all hooked up correctly. My friend is a fellow employee and tech at the bmw dealership we work at so I trust him. It sounds like the bov is teetering on opening up but just doesn't have enough pressure. When I hit the throttle a little more it goes away. Any ideas guys?

Nothing??

if your teetering on on the throttle and off the bov is going to do the same

i just mash it and let off completely

1 thing to note, i had a problem with. Make sure that vacuum line isnt getting pinched at all(by the brake fluid resevoir, or something else) Mine got wedged in a spot once and it kept the valve from opening after letting off... so not good.

I'm just driving the car normally at 35-40 mph doing the speed limit. Nothings caught, pinched or restricted in anyway.
