Bongo Fury

Just got mine from Allans,they are straight forward with easy to follow instructions,nice finish to the blanking plates,would not want to mess around making my own,reckon they are worth the £12

Hi Neil
How do they fit in the exhaust end?

You remove the EGR unit via the 10mm bolts at either end,remove the gaskets and replace with the blanking plates and reconnect using the 10mm bolts,job done
Neil

I haven't looked at mine, but thought that the exhaust end was a screw-in jobby, as shown in the last photo on page 1 of this thread.

Been in touch with Allan to order mine.

neil/di - v interested to hear you view pm how the Bongo feels / drives once its been 'done'

Allan........what is the benefit of using a blanking plate over disabling the vacuum pipe on the actuator?

I fail to see any benefit at all Dandy. It will do the same job. The idea of using blanking plates should be so that you can remove the whole EGR system thus reducing weight and providing easier access to the engine and ancilliaries. Putting a blanking plate between the pipe and the manifold is just making the job of disabling EGR so much harder.

Mike will let you know,I hope to fit it next weekend

Allan........what is the benefit of using a blanking plate over disabling the vacuum pipe on the actuator?

Many of the problems that I've seen on with the EGR have been due to the pipe itself - hairline cracks or pinholes. So I like to take the pipe out of the picture.

If the EGR spindle is coked up and stuck either in the open position or unable to fully close, the problem can't be solved by putting a ball bearing in the actuator pipe because exhaust gases will still constantly recirculate and it's possible that they could eventually contribute to heavy smoke or diesel knock.

At customers requests, I've fitted a fair few blanking plates to Bongos, usually to cure a whistling noise and evidence of escaped gases.

On many of these, the whistling has not stopped by fitting just the 1st blanking plate at the exhaust side of the EGR.

Over time, the steel pipe from the EGR to the manifold can get a hairline crack at the welded union or develop a pin hole. Pressure in the manifold can whistle out through these. Fitting the 2nd blanking plate to the inlet manifold side has stopped the whistle completely.

As the 2nd plate is quicker and easier to fit than the first one, it makes sense (to me) to fit them both at the same time. And it will prevent the above problem should any hole eventually develop in the pipe.

Around 8 years ago, I was a Pajero owner and we started to debate whether or not to blank the EGR. We're still debating! The Pajero EGR does operate slightly differently to the Bongo. If you're interested, this link's to the discussions on the Pajero Owners Club:

The EGR is there to recirculate the exhaust gases into the fuel mix, which retards the burn and some say it helps to prevent temperature peaks under certain conditions. In 8 years of blanking Pajeros, there have not yet been any recorded incidents of over heating that can be attributed to the EGR removal - another hot debate!

Many of the problems that I've seen on with the EGR have been due to the pipe itself - hairline cracks or pinholes. So I like to take the pipe out of the picture.

Fair comment and all very accurate.

Thanks Allan

Just done the blocking the pipe job, and will see tomorrow if there is any difference.

If using this method what if anything is needing to be done at the vacuum pump nozzle, was this just left open?
Cheers

I fitted the kit that I bought from Allans, nice and relatively easy job - a bit fiddly at the 10mm end but easy enough. However, like a plonker I broke the stub off the way one valve that takes air off the inlet hose. This links to the actuator (?) - It has broken actuator side so there's no air leak into the inlet.

Am I right in thinking that now I've blanked the EGR off the this isn't needed and I can just leave the remains if the one way valve in place?


Be good to know.

Is it the same as this link
