Does not blanking this pipe off render the oil cooler " ineffective?
No, as it just goes through the block, where the majority of it flows anyway.
Cheers

You may find that return pipe was blocked off by the "Monkeys" at Landrover, It was a change they did on later production
vehicles, Just used a black rubber bung ( no pipe) but they left the hard pipe in behind the engine bay.... My 53 plate is the same.
Thats the pipe i was on about blanking off when the EGR cooler is removed....
Though I did notice there is a pipe fitment on the bottom of the rad belown the boost pipe, which looks like where that blanked pipe could connect. Am I right?
EGR is normally activated at lower RPMs ie low power use and cruising speeds ..the two solenoid valves one works the butterfly in the intake this restricts in coming air so the engine is allowed to pull air from another place ..ie the egr valve ..that has the 2nd solenoidHi,
Can I come in on this one? It seems to me e that it's totally unnecessary to do anymore than just disable the "egr" ! This can be done in a number of very simple ways: remove the vacuum supply to the two "egr" actuators and block them, remove the power supply to the two modulators or block off the vacuum supply at the "t" joint on the vacuum pipe leading to the brake servo.
I personally would not like to "mess" with any of the water plumbing! I'm now rather of the opinion that the removal of the "egr" on my 04 Disco lead to my problems. The water return from the oil cooler had been blocked off! As I've said before I think that a "troop of monkeys" played on this engine!
When it's so simple to disable the "egr", I'm amazed that so many companies make and supply kits for the job.
While on the subject of the "egr" , does anyone know when its actually "activated"? I presume that the two actuators are operating independently! Is it perhaps that the butterfly is shut off on overrun to help slow the engine down. When I have the time I'll rig up two lights and try to see.
