Hi Smokebelch/Galen,

You are quite right, South African Land Rovers were built to Euro-2, and 2003 onwards apparently had no EGR or ILT.

Bell Auto Services UK stock a kit of 2 parts, an EGR exhaust manifold blanking plate and a straight metal pipe with flange to connect the intercooler rubber pipe straight to the inlet manifold, at £45 inclusive.

Apparently these or similar parts were used on the SA Land Rovers.

Personally, I will check to see my EGR and ITL valves are not stuck open, and then I will simply unplug the wiring from the two EGR and ILT modulators. I don't know if this will be seen as a ECU fault, but it will give me some idea of any increased performance.

I've finally decided to go the whole hog.

I've whipped out the ILT, EGR valve, both actuators and all the vacuum plumbing that went with it.

I've left the EGR gas cooler hooked up for the moment, but at some point i'll unplumb that from the water system also.

Going nicely now is she?

Did you de-gunge inside the inlet manifold?

A short length of copper pipe will by-pass the EGR cooler (what a LUDICROUS idea anyway) and then you can sling the thing in the bin.

>Going nicely now is she?
Yes. No great difference in power and the such, but that bloody annoying heavy engine brake effect when you lift your foot has gone.
Inclines seem to be a little easier on the loud pedal too.

>Did you de-gunge inside the inlet manifold?
There didn't seem to be much need to. There was a small amount of soot but really nothing to remark upon.

How does copper fare against the organic acid stuff in the cooling system?

Likewise.

I have just removed the two vacuum pipes from the ILT and EGR valves and plugged their ends, as a temporary trial.

No discernable power increase but the old girl seems to cruise along at just a touch of the throttle, and has a cleaner pick up when the go pedal is depressed.

I will be interested in the future MPG, as I'm sure it will be better.

Twenty five years ago, due to lack of engine and autobox spares, I replaced the 4.5 litre Daimler V8 in my 1965 Daimler Majestic Major, with a 300 BHP tuned Pontiac lump and autobox.

I have been reading my old american engine tuning book for the 350 cubic inch (5.7 litre) Pontiac V8. It says: remove the EGR valve, all associated vacuum piping, and all the engine temperature switches. Find yourself a trash can and dump the lot into it. You have just gained an extra 50 BHP!

The book was right, the difference was amazing, improving the MPG as well.

I ditched the EGR on my '99 TD5 back in the Spring and was chuffed to bits with the improvement. Anyway, the car has just flown through the MOT with it fitted, I asked the tester his opinion and he said it makes no difference, it the engine is healthy it will pass emissions whether the EGR is fitted or not.
