Quite possibly an old topic here but I have to see if any boffins have any answers....

Thinking of blocking the EGR on my 1HD-FTE, for some obvious reasons:
However these are just assumptions for now.
1. Cleaner intake, better flow.
2. Cooler air, the HDJ-78RV does not have the luxury of an intercooler. (yet...)
3. Better response, more power, if not recycling gases then should be quicker when you need to put the foot down.
4. Improved fuel economy.

My misgivings are as follows:
1. Does this recycling of carbon in any way contribute to the longevity of the 1HD-FTE? is this the reason they are such an indestructible donk?
2. The computer turns the EGR on in periods of little demand, I'm assuming that the computer ALSO lessens the amount of diesel to compensate for a reduced oxygen flow. Does this mean with a blocked EGR the car will run lean? I know in a petrol this means hotter engine, however in Diesels I'm prone to think cooler.... In which case NO PROBLEM. Or is the fuel unchanged.
3. Blocking the vacuum pipe to stop the actuator is fine if the EGR is functioning correctly, but if stuck open should I fit a plate over the EGR pipe to make sure?
4. Extra pollution. Had to add this, even though Brownwin Bishop can take a joy ride in a helicopter that would spit out 1000 times more pollution that my troopy ever could. This one is for the greenies.

Cheers for informed answers, no guesses thanks.
