Okay, so I answered my own question. I connected the vacuum port on the bottom of the intake to the catch can and from there to the valve covers. I drove for about 6 or 8 miles, then heard a terrible noise. I pulled over and popped the hood. It sounded like the belt was squealing, but when I looked under the truck, the noise seemed to be comming from the bellhousing or rear main area. The noise would go away while driving or when I gave it gas, but at a red light it would start again. So I drove home and plugged the intake port and put the little filter back on the catch can. I drove probably 20 miles, no noise. The question is, what the hell could the vacuum from the intake only cause a noise like that? And did I do any damage? Maybe some of you guys that have been inside these engines have any ideas.:dontknow:
