Dan this is excellent! Just what I want to do! but mines only done 90k with the egr still working then Iv disabled it via vacuum.. so isnt that bad, I will be getting rid of the EGR completely when I strip it all and clean it.
More pictures the better! great to see how you've done the valves & flaps etc.
Looking forward to seeing your truck get back to tip top running condition!

Thanks, I am looking forward to seeing the improvement! Ye I want to do the same, I am hoping to loop the coolant pipes for the egr cooler and completely blank off the egr exhaust/inlet pipe at both ends and remove the pipework, would be nice to also completely remove the valve itself but that isn't something I am worried about at the moment.
Here is what the flaps look like off the car:

And here are the intake ports in the head:

So got my little friend Henry and started scraping out the ports to the head and using the hoover to suck out the carbon:

Intake manifold cleaned up pretty good:

Hoping to finish cleaning out the ports in the head at the end of the week when i'm back at work, it's the most time consuming and awkward part, especially the rear ports as they are hard to get anything large in to scrape out.
