EGR kit #4

[Brian Carlton]

Due to multiple requests, I will again offer an EGR blocking plate kit to allow all owners of 617 and 603 engines to completely remove the EGR valve "for testing purposes."

The kit consists of:

1) intake plate made from .125" stainless steel
2) (2) SS button head cap screws
3) OE EGR gasket
4) exhaust plate made from .017" copper
5) tube of copper sealant good for 700°F.
6) Detailed set of installation instructions

Here is a photo of the components installed on a 603 engine:




The cost of the kit, including shipping, remains at $29.00.

So, if you wish to purchase a kit, please send an e-mail to hpcs at csi.com and let me know how many kits you wish purchase. I'll advise of my mailing address in a return e-mail.


Please do not post your desire for a kit on the forum. I need a separate e-mail to keep track of all interested parties.

I keep thinking: why would I do that, when a bb is (nearly) free?
Well, the picture tells the story, sure cleans up the engine bay, I like your kit.
Now to include a new pipe from manifold to turbo instead of the plug, that'd be a really really nice kit, think you can do that for under a C-note?

It's not a plug........but a copper "cap" that blocks the exhaust outlet. You can get a better look by tapping that outlet for 3/4" NPT, but, you need to remove the manifold to do it. I did it on the SD and it's a great mod.

G'mornin',

I just sent you an e-Mail......I want one......

Could someone explain what benefits will I get from removing the egr valve ??? The plate looks great and its a good price ! but how will it help !

[Brian Carlton]

There is no benefit to physically removing the valve other than visual effect under the hood. You can get the benefit of no EGR by simply disconnecting and plugging the hose to the EGR valve.

So, for those of us not in the know, what is the "benefit of no EGR" that could be obtained by either disconnecting and plugging the EGR hose or removing the valve (for experimental purposes)? Are there any detrimental effects?

Yes, I'm a mechanical noob.

The benefit is, you are not getting any exhaust dumped into your intake manifold anymore. This means you won't have 1/2" thick layer of oil soot caking the inside of the intake. There is no information that says this oil soot is detrimental to performance however. So, the benefit really isn't much. It's a feel-good maneuver.
I bought Brian's EGR kit about two years ago, but since then I found '79 SD manifolds on eBay and just used them instead. The intake, which had never been cleaned, had no soot in it, unlike the EGR intake from my '85 which had major buildup. A lot of the time the old EGRs are faulty anyway, mine failed the vacuum tester and was basically plugged solid with sootcake. Keep 'em separated I say. Maybe theoretically the intake valves are better off not having to deal with the soot?

Edit:
I guess there are quantifiable benefits, per Brian's post. I thought it was mainly feel-good. However since diesels are emissions-exempt where I live, I feel good.

There's quite a bit of discussion in the archives on this.

The EGR causes hard deposits to accumulate in the intake manifold which restricts airflow over time. There is no certainty that the deposits will remain in the manifold and not break off and enter a cylinder.

The EGR also causes a slight reduction in part throttle power and a slight reduction in fuel economy.

Be advised though guys, if you add this egr block off kit you will then need one of these rear wings to keep her on the ground.

That has got to be the prettiest thing I have ever seen! Nice color, too.

1. No More "Black Goo" in the intake/vacuum system!

[bgkast]

I have one. It is a good kit. Too bad I had to get rid of the shiny part when I modified the manifold for my intercooler.

I've used more than one of these kits with great success, bump for a great product at a great price.

This means I should be prepared to remove the intake to degunk it?

What parts do I need to do this? What else should be done while I have the intake off?

Also, this would be the time to try to install the block heater right (I have the lower radiator hose kind but would rather have the real deal)?

Thanks!
