Defender Td5 2003 - Egr / cooler delete

[gary goodwin]

Hello,

I just bought an EGR blanking kit for my defender Td5 but it only included 1 blanking piece (for the exhaust end), my wagon has the egr cooler...there's a lot of conflicting info about leaving the cooler in, should i just blank off the left side of the cooler, before the EGR valve and leave all the pipework in?

Also, my EGR valve has two breather pipes connected on top, do both of these get blanked off ?

Any help would be great thanks!

Put the blanking plate between the exhaust manifold and cooler....

I blanked off the EGR on my TD5 in fact got it removed completely because “it will perform better” and.....it made no difference at all.

Thanks everyone, Egr delete is done to stop all the carp going back into the engine... you probably wont notice a power increase, but your engine will be much cleaner and last longer.

You can achieve the same effect as the blanking-plate by simply disconnecting the two little vacuum-lines from the two vacuum-capsules on the 'nose' of the intake manifold.

The unit on the manifold has two flaps, one - normally wide-open - allows air from the intercooler into the manifold. The other - normally closed - allows cooled exhaust-gases into the manifold.

When the EGR is activated by the 2 solenoids inside the front wing, controlled vacuum is fed to the two valves - partially closing the 'air' flap and partially opening the 'exhaust' one, so the engine then gets a mix of air and recirculated, cooled exhaust.

Pulling the 2 vacuum-lines off and plugging the ends of the rubber pipes means that though the ECU will be signalling the solenoids to feed vacuum to the valves, it never gets there so you get uninterrupted fresh-air going into the engine.

Quick, simple, instantly reversible (in case future MoT tests start requiring a visual check-for-tampering/removal of emissions-control systems) and, above all, entirely free! What's not to like?

The cooler is basically a heat exchanger between the cooling circuit and the exhaust gases. If you put the blanking plate at the end, and keep the cooler active in the circuit, then it contributes to warming up the coolant . It might help getting heating a bit quicker when it's cold.(although possibly slightly since it is now a dead-end)
