besides of havng a cleaner manifold(if egr is blocked) any other benefits??more power or mileage???Best way to do it??place bb in hose??or completely block of tube???thanks

Not recommended on this model for several reasons. It's not a simple thing to disable since the engine monitoring system will trip a CEL if it detects the EGR is not functioning. It's best not to mess with it, IMHO.

I'm with nhdoc on this one. Though there is this a thread out there, the only one that I have noted with any level of success in this area. I do not forsee myself attempting this mod at this time. I'll have my IM off soon doing some maintenance and can see how dirty the EGR and the intake is at that time.

But not certain what the results have been and if this mod is still working without issues.

I am hashing around the idea of not doing that. Instead find a way to vent the crankcase. The way I see it, 2 things need to be there for sludge to form. Oil vapors and EGR fumes. Take the vapors away and you might be eliminating your problem. I have seen way, way less stuff in manifolds where the crankcase vent is removed and set out to either the exhaust or just vent. On the Ford Powerstroke engines it seems that the intercooler boots are always sweating oil and dirt sticks to it. I have plumbed my vapors to the exhaust so there is a negative pressure force keeping the crankcase under vacuum. So far the results are encouraging. No oil leaks and the boots are clean as a whistle on the outside. Next year I am taking it off to see what they look like on the inside.

I don't see the need. I pulled my intake off a couple of weeks ago to repair fuel leaks...sure, there was a layer of oily goo in there. It's been 25K miles since it was cleaned out last and it didn't need cleaning yet. The last cleaning was at 115K miles and probably the first time. There was gunk in there but not that much, probably from 1/16" to 1/18" built up around the intake pipes. Cleaning it out had no noticeable effect on performance. Made me feel better, but did nothing for the car. So, in short, if the purpose of the mod is to prevent gunk from building up in the intake, gunk that need cleaning about every 100K miles, then I just don't see the purpose in doing it. I honestly think there isn't anything to be gained in the way of additional power by cutting off EGR, even if so it is probably just marginal improvement...I'd just leave the system as it was designed...mine's worked fine for 9 years and I don't plan on tinkering with it - I'll just plan to clean the gunk out in 75K more miles

thanks for answer,will just leave alone.

With the arrival of ULSD and use of a low NOACK engine oil, the build up of garbage within the IM can be held to a minimum. As noted, venting the CCV vapors to the atmosphere works.

I would not vent the crankcase to the exhaust in front of the catalyst. I also wouldn't vent them to the air on a daily driver. Doing so on a high-performance limited-use engine is another story.

Me neither. On my powerstroke, even tho it didn't have a cat, I vented it a few feet from the exhaust tip.

Why vent it to the air when you can use the exhaust to create negative pressure like the turbo is doing? Only difference is that the turbo sends the oil mist into the pipes and intercooler, etc, etc. There have been some reports of oily boots slipping out under higher boost on some of the Powerstroke Forums.

Actually, I think they vent it the way they do to create crankcase vacuum which seals the engine rings to the walls better.
