Another EGR post / saga

So after reading a lot about the pros and cons for removing the EGR I thought sod it lets give it a go. Improved performance and greater fuel economy are often linked to removing the EGR but in other posts I have read that you can expect very little, if any, of both. However, not breathing in the old exhaust gases seemed to make sense.

So I purchased a x8r kit on Sunday then removed the engine and fan cover to spray the Allen bolts on the manifold with some penetrating fluid. Then sprayed some more, and some more at 2 hourly intervals as I had read theses bolts were a nightmare to remove.

Monday arrived and I set about removing the EGR after spraying everything again. Top bolt came undone with no problems. Great! I thought, even while thinking that something is bound to go wrong, it is a 20 year old vehicle after all, not to mention it's a Land Rover.

And lo and behold the bottom bolt was stuck. Scared that I would round it I tightened the top one and ran the engine for a while thinking that the heat might help. It helped warm my hands and that was about it.

Tried again and thought I felt it move. But it was just me rounding the hole. ****! What now.

Pick up phone to local independent LR specialist. Can do it but can't get me in for 4 weeks. Can they recommend any one else. Indeed they can. Phone the guy up and he says come on over. 10 mins later with the vicious fan off and using a bolt removal tool we are back in business.

X8r product arrived this morning. Looks good and got the right pieces. Fitting is easy. Removed the blue coloured hose and plugged the end at the solenoid. Engine start and now leaks.

Now. Did it make a difference.

Drove a familiar route and I have to be honest and say, after I warmed it up, it did accelerate quicker and in higher gears. The turbo certainly spooled up quicker, at least it felt like it did.

Overall a better drive? Well, I could be just hoping for it to be, it seemed so.

No idea about fuel economy yet but I didn't buy the Defender to be good at fuel saving.

So I would recommend doing it. Would recommend the X8r product and if anybody lives at the top end of Essex and needs a LR Specialist I would certainly recommend the guy who got the bolt off. PM me for his details.

I fitted this kit and could feel no difference whatsoever in the performance afterwards. Maybe your EGR valve was faulty in some way, if you noticed an improvement.

But ROW Defender TD5’s weren’t fitted with an EGR valve so removing it will do no harm.

It may be that my hopes are clouding reality. A placebo effect?

But it does feel quicker

Hard to say really! I've done exactly the same EGR removal as you, using the same, excellent kit as yours.

When I removed it I found that my EGR valve was very clean, as I mainly do longish runs.

After the job was done, I have to say, I noticed no difference in performance at all, but then, I was not expecting or hoping for any, doing the removal simply to keep the inlet manifold & engine internally cleaner without it inhaling exhaust gases.

Perhaps this eliminated the placebo effect.

Cheers,

At full power the only advantage is that the inlet is removed sao a little less resistance as no exhaust gases are let in on full throttle. Only in the mid range (normal driving

) exhaust gases are comong in the inlet. Roel

Anyone knows if the EGR solenoid (where the blue vacuum hose goes to) should be covered/plugged? My friends TD5 is not and works great Mine is plugged but makes a weird sound like something is working to much. Kinda like when you take your vacuum cleaner and put your hand over the tip.

Keep quiet when you take for MOT.
You have now modified your exhaust system which is illegal.
Also don't tell your insurance

The evidence for benefit is anecdotal as there are no (as far as i am aware) proper research papers that confirm the benefits.
As you may guess i have re-instated mine.

I actually refitted the EGR not too long ago because I'm a city dweller and can't find an excuse valid enough not to reduce the NOx emission. If I notice any difference, than I would almost say it runs a bit sweeter, oddly enough.
Our '97 BMW 318 has an EGR too. It's probably the slowest car to pull up when the lights go green, but it has never let us down in more than 360k kilometers.

I would suggest that you plug everything. When the ECU is trying to activate the now-missing egr it is opening a valve and allowing air into the vacuum lines, the same lines that provide the brake servo.

One big benefit is ,the M.A.P, sensor stays clean,, did you take yours out and clean it [brake cleaner]
