EGR delete OEM intake pipe

Adams · **Posted:** Wed Oct 28, 2015 12:09 pm

Hi everyone,

I recently stumbled upon a 2004 Liberty CRD manifold intake pipe from the European market, the part number being 91092218f. It's interesting because it's a one piece design without the FCV, just a small EGR port on the side, hence seems ideal for deleting EGR on the 2005+ cars. Seller says it's from a 2.8 CRD (there were less powerful 150 bhp versions sold in the EU till 2005), however I can't say for certain if it's not from an even older 2.5 VM CRD. Anyways this looks like it should fit the EGR equipped 2.8 CRD and if so could be a simple way to delete the recirculation system altogether. Did anyone have experience with such a solution (would like to confirm prior to buying and stripping the EGR...)?

Thanks!
Adam

really interesting :POPCORN:

wow, it's the weeks intake kit with an egr port. Prior to FCV? hmm, I guess you'd need the bolt spacing and the internal diameter of the tube to know if it would fit. Might also require a longer CAC hose, but it looks pretty long.
You familiar with Sasquatch Motorsports intake elbow kit? It might be a better route for you.

So I see that it is not something that was discussed here or tried before? If so I'll just get one of these and see how it fits (when I'll have some spare time for the jeep that is...).

Yes I am, however frankly I never intended to remove the EGR entirely, just disabled it fully and removed the "flap". The above solution did interest me though - for the sake of the exercise I guess :roll:

And I'm getting a strange feeling it might fit

and here is nice to have something that seem "original" when we go to the revison .. or the emission test

How would the egr work without an fcv? Did it just flow a miniscule amount whenever the manifold pressure was low?

Pre 2005 CRD has no FCV. It will bolt onto the 2005 on camcover/inlet manifold. Samco make silicon hoses to fit on the older 2.8. The EGR is not so effective on the older version hence why they tend to more reliable. Personally I would go with the weeks elbow.

there is no FCV , because the turbo is a non VNT , but with a wastegate in the pre 2005

Cool, thanks for the image! This might be really useful for people in CA and MA and other restrictive states that can't sneak the Weeks elbow kit past the emissions folks. I wonder if the part can be found online other than the occasional Ebay listing? Any idea how much one can be found for?

Really ? . . . . . . Is there any details on what it is and is the exhaust manifold standardized to a T25 flange or something? That could be of interest to some people looking to do a turbo swap around here in the foot steps of Dieselguy.

yes I'm sure in the 2.8 crd pre restyling is a 150 hp , is the same engine but change the egr position and I think the exaust manifold .......sorry do not know what doese it mean T25 flange ...... the vacuum actuator in our VNT in the pre 2005 act the EGR and the turbo is a normal wastegate controlled , .........have different glow plug and do not have the predisposition for the in line fuel pump ...........and is well constructed , for detail you can download the part fiches for the 2.8 export model this is only what I know on this model

The cylinder head is the same on both models as is the cam cover. Any item that bolts to them will be interchangeable. I would guess it would be expensive to purchase an intake elbow or exhaust manifold from new and that's if they are still available.

Unfortunately I couldn't find a decent photo of the other side of the engine but I would suspect the egr system on the -2005 CRDs would be controlled by a volume valve or similar (as is in case of many older cars).

No idea how accessibility looks like in the US, I got mine locally for under $20 including shipping

Nice, that's a cheap elbow!

Just ordered one off e-bay. $55 shipped to Ohio so its worth a shot to see if it works.

That intake elbow in the OP's first post has an EGR port. It looks like it is in a different spot compared to mine, but the port is there.

Yeah, there seemed to be two kinds regarding EGR port orientation. I got mine today, will match it to the OEM gasket in the evening. EGR port is under 1" ID and I will either weld it shut or tap and blank with a short bolt and some thread sealant.

I agree that the Weeks Elbow with the way to go. Its so much easier to just pop off the band clamp and pull the elbow off to get in behind there. Taking the stock elbow off is a PITA.

Yeah, this probably won't give you the easy access to the glow pugs like the Weeks does, but then again, you could pass emissions, and then put the weeks elbow on :2cents:

Well we'll see - it'll most probably be some time till I put it on the car but I will post feedback regarding ease of installation and accessibility. One thing is certain - I will be using studs with nuts instead of bolts which should facilitate things a bit. So far I can add that the pipe's flange fits the 2.8 CRD OEM gasket

Furthermore the pipe's exit is 63 mm in diameter so slightly smaller than the FCV equipped car's (65 mm from memory?), which is actually perfect for my intake.

And two photos for reference:
