EGR VSV Relocation - Toyota Nation Forum : Toyota Car and Truck Forums

Today I decided I was going to put on the new VSV whether or not I could get the old one off.

On the firewall, in front of the passenger side, there are two studs. Unsure what they're used for, but it allowed for a perfect place to relocate the new VSV. I used the lower stud. I put one nut on as a spacer, planted the VSV, and secured it with a second nut. The connector was able to reach perfectly. I haven't secured the vacuum lines very well yet, but they also reached just fine.

Is it important that the vacuum hoses remain the same length? Can I replace them with shorter ones since the VSV is now closer to both the EGR Valve and Modulator?

And by the way, I still could not remove the old VSV. The bolt is now slightly rounded. The socket grips it, but when force is applied it just slips. It doesn't really matter that it's still there, but if a shop ever does any work on my car, I will probably have it removed at that time. Being able to stand directly underneath the car would make it a ton easier.

I tried to take a picture of its new location just now, but the lack of light isn't allowing my camera to focus properly to get a shot between all of the various crap in the way.

That sucks. VSV's are a bitch to get to if you don't have little arms.

But that wasn't too bad of an idea! I wouldn't have ever thought of it.

I don't think the length will really matter. It might be beneficial to snip it...

I know when people upgrade their intakes they should trim hoses then, so I would assume for the VSV it's the same.

Be sure to use the right inner diameter of hoses since NAPA and all the other chains tend to carry SAE rather than metric.

Where can you buy metric hoses then? Auto Stores don't sell them. And the parts guy at the dealership told me their technicians use the same stuff you can get from the auto stores.

SAE hoses will be fine, just make sure you clamp them on correctly and check to make sure they won't slip off.

I honestly don't know why Toyota didn't put it there in the first place. Much more practical location.

I'd like to find a different bracket to use than the one the VSV comes with, but this suffices for now.

I forgot to mention, that was a great idea!

I located my (EGR) VSV in exactly the same place....about 4 years ago when I had to replace the EGR components. The standard location on the back of the block is monumentally stupid, in my opinion. Even if you need longer vacuum hoses for this, it is NOT a problem. Mine has worked without flaw all this time. I simply abandoned the old VSV in place....it's still there, in the stupidest possible location....and always will be.

Great improvisation!

Are the old hoses in condition for reuse?

They are, but they're a bit too long now. Doesn't really cause any problems, just a lot of unnecessary slack. I will cut some bulk hose to length tomorrow and make it look all pretty.

Ok, if you already bought bulk hoses that's fine.

Otherwise I was thinking maybe cut the old hoses to length, unless you need them in the future for other things and don't want to cut them down now.

Ah, well I've had it for a number of weeks now. I bought a decent lengths worth when I started replacing the various hoses. The old ones aren't broken or anything, but slightly dry as you might imagine. I see no reason not to replace them. Bulk hose is super cheap, and one AutoZone gives it to me for free sometimes.

I'll probably reuse the hose "pad" that was around the original pair.

Cut some bulk hose to size today. It's looking quite nice now. Everything works well.

I didn't have my camera with me. But the next time I do, and the front right wheel is off, I will take a picture and post it here.

***JohnGD*** · 01-26-2010, 10:30 PM

Sounds good!

haux · 01-28-2010, 03:24 AM

I'll post a more proper picture of the actual VSV location in a few weeks, but this is one I took yesterday.

You can see how the new hoses are routed against the firewall. One goes from the top right of the EGR itself, and the other comes from the top left of the modulator.
