Does anyone have pics or diagrams of smog pump and egr plumbing for a 95 f250 with a 351? The broken factory manifolds were replaced with summit pacesetter shorty headers. The shorty headers only have one port. egr? I think the factory manifolds had two ports, one on each manifold.

 

No, the port is for the O2 sensor and AIR system.
The EGR does not connect to the exhaust manifold or header pipe, a header pipe runs from the exhaust manifold and the cat or muffler and has holes for the O2 sensors and the AIR system.
Maybe this diagram will help and if you need a blowup of an area in it post back.

The AIR system:

Strange.. that's not how mine is routed. The EGR was connected to the front of the passenger side manifold, and the air injection system is routed to the back of the cylinder heads. There are also 2 valves in the Thermactor system, 1 near the pump that dumps all air to atmosphere, and the other at the back of the engine that diverts air down to the cats instead if into the heads. The replacement headers I have as well as others I have seen have a fitting on the #1 tube for the EGR, and fittigs in the collectors for the O2 sensor/s.

 

I stand corrected, it does go there on the 5.8.

Those diagrams help.
Thank you!

 

I know this threads aged a few years but I found it on a search.

All of the diagram links are bad now, but I'm looking for the same info.
I have just acquired a 1995 351w motor and I'm trying to make sure I hook things up properly. It's completely different than what I'm familiar with in my 92 5.0, but its like Conanski describes on his 5.8.

Anybody have pictures or diagrams?

 

The link's above still work for me... With the thermactor air injection systems I have seen there is a steel tube connecting the heads at the back, and a couple diverter valves and plumbing connecting this to the air pump and the cat. The valves are vacuum operated by a couple solenods commonly mounted near the coil, and the valves are either on top of the motor or down beside it on the passenger side. On HD trucks there may also be individual air lines into the top of each port on the exhaust manifolds, why Ford did this is hard to understand.. it's completely redundant since the heads are machined internally with the exact same plumbing.
The EGR valve is connected directly to the front of the passenger side exhaust maniold.
The O2 sensor will be located in a small crossover tube right in front of the first cat, or in some cases in the back of the exhaust manifolds.

 

The links work for me now.

The sticker on the valve cover refers to heavy duty trucks, and the AIR system matches the 8500 GVW F-series diagram: (http://i54.photobucket.com/albums/g9...aust/19955.gif),If you look at that diagram, the air tubes go to the collectors on the exhaust manifolds as on this 351w. There is no port on the back of the heads for any air. I believe its fed emissions rather than CA, the motor came from Oregon.

It's a MAF/SFI motor from a 95 f250, a HD i'm guessing.

The EGR is like you describe and as shown in the 5.8 diagram. The crossover tube 02 sensor sounds like what was originally on my 92 5.0 bronco, but I have a computer from a different 1995 5.8/maf/f250 (this one was in CA) that I think is meant for two 02 sensors. Chilton shows 2 for a 95 CA 5.8.

What kind of smog equipment do the 1995 CA/MAF light duty/half ton 5.8 broncos/f150s have? I think thats what I'm going to need to pass smog, including the EVAP stuff.

Hope I'm not in over my head, I thought I was lucky to find a 5.8 roller. Am I going to need find different heads with the air ports in the back?

Also, I'm wondering how to tell whether the flywheel thats on the motor will work with my e40d. Last question, are you aware of anybody that makes good quality CARB approved longtubes with the EGR tube for a 5.8?

Really appreciate the info.

 

I picked up a lot of the light duty smog parts at a junkyard of a MAF/SFI 95 bronco. I got the crossover tube, the air injection hardlines, valves, hoses, vacuum lines, vacuum canister, the other black canister, and air release valve. I noticed that the egr is slimmer and has no EVP on top, looks totally different then the one on the heavy duty motor, which resembles the one on my 92' 5.0. Anybody know how this egr setup is different than whats on my 92 and the 95 heavy duty 5.8 motor??

Also what is the electrical control thing mounted to the throttle body on the passenger side with the small hardlines going to it?

I still need to find another 94-95 5.8 bronco to grab an engine harness from.

Does anyone have a good engine bay diagram for a 1995 CA 5.8 bronco or f150??
