So I did this mod and now I have a VERY high-pitched whistle coming from my EGR(I think). When I disconnect the hose going to the components on the firewall(O2 sensor?) it stops and the pipe from the EGR is just sucking. I have tightened the EGR mounting bracket as much as I can and I also replaced the gasket for the EGR to the manifold, Is there something obvious I'm missing?

If you run with a bypassed egr valve, apart from lower mpg and the cat seeing unburned fuel, is there something else to be concerned about?

I've done the mod, just because I had the EGR off and the cut off wheel and dremel were already out.

I need to know how to do the bypass. I know that 6crew had an awesome thing on it. But that site doesn't exist anymore. So I never got to see it. I'm 90% sure how to the bypass, just need instructions, not visual aides...
