hello everybody,

I've been lurking for a while now. I had my engine rebuilt and the shop was a nightmare so I'm trying to clean up their mess myself. I am in need of help identifying a few things. I have repair manuals, but they have not been helpful and neither have my internet searches.

I found this hose on top that they just plugged up with a screw. I have looked at several diagrams and can't seem to figure out where it should be attached.

The next one is some obvious wires that were clipped attached to the ?EGR??

The vacuum line is permanently capped on every 3ZVE I've seen. I'm going to guess that Gomer pulled the cap off just to see what it did, and then lost the cap. The plugged hose looks, uh, redneck, but will work fine.

The clipped wires are to the EGR temp sensor. So far as I know, the sensor is only required on California (maybe Canadian) models. So it's possible you have an ECU (and harness) for a 'Federal' vehicle, but someone put in an EGR valve from a California truck. Rather than unscrew the temp sensor and plug it correctly, they used the ghetto method.

Sounds like you've got your work cut out for you. Good luck!

thank you for your response. I continued my research after posting and saw that others had that hose connected behind the engine to another hose. Does it not matter one way or the other?

Also, does it matter where the other hoses are connected to? I think mine are all out of whack.

Thanks again!!

Hmmm. Either I'm right and "others" don't know what they're doing, OR I'm wrong, in which case I usually try to admit it. But it's all just a mystery because you didn't provide any cites/links to these unknown "others" with their wacky vacuum hookups.

This isn't mine, but is typical of what I see.


Uh oh, you've figured it out. All those hoses are really just for decoration. If you remove ALL of them your truck will be able to haul 4 tons and reach 160mph.

Okay, I understand you are just trying to be polite (thank you). Some very smart engineers spent years figuring out what all those hoses have to do. Some of them can be mis-connected and the truck will still run (sorta), but you have to be pretty smart to know which hoses those are.

The good news is you have a sticker on the underside of the hood which tells you where all the hoses on YOUR truck go.

you're right about the plugged hose. Thank you.

also, the diagram under my hood is gone, but I've found many online. Thanks again for your help!
