replacing exhaust manifold

[rmb1393]

My passenger side exhaust manifold is very rusty and I feel that my ebv is getting a bad reading from the ebp if my manifold is letting air out of the tube or manifold itself. How would I go about replacing my manifold? Do I have to pull the motor?

Any suggestions are appreciated thank you!

Just pull all the bolts and replace it. It is a little harder when the motor is inside the truck but it can be done.

Manifolds rust, its what they do. They are pretty thick so I wouldn't think about changing it out unless I was positive it was leaking. The problem with your ebpv could very well be the pedestal, sensor, or ebp tube being damaged/ clogged. Is you valve staying closed or closing while you drive?

[rmb1393]

Yes it is staying closed during driving and will close and open while driving which is getting rather annoying.

I'd clean the sensor and tube before a manifold.
or just unplug the dang thing from the pedestal

i am gunna have one of my friends help me put a switch on it to turn it on/off. have people done this with success?

That's exactly what my 99 was doing anytime it would be below about 30 degrees outside. I could never build boost because the valve would also close at just the right time and my fuel mileage went down also. I ended up putting on a non-ebpv pedestal and the high flow outlet on the turbo and no more problems. That was some of the best money I ever spent on that truck. And I will be putting the same parts on my 01 this week.

do you recommend a non ebv pedestal and outlet? i know it will get m better flow but is there anything really noticable?

i ask because i know the combo is about $200 and a good amount of work

I would try cleaning the tube with an air hose and spraying the sensor out with some carb cleaner before I started turning wrenches on the tube, with the rust build up I've heard its a P.I.T.A.

so beneath the sensor where the line begins try blowing air down that opening?
