erg valve and bits for ecconomy

[thin on top]

Well I have now blanked of the erg valve, removed the butterfly valve and washed out the intercooler and add 2T to the diesel.
So today went for a run up the Arnhem Highway from Darwin east towards Kakado. Yes I think it runs smother and maybe quieter. I had to stop after 90km as the road was closed due to floading. Now that was a site to see people standing knee deep in water on tarseal, flicking lures further down the road hoping to catch a Barra.
When I left home I filled both tanks, and 189kms later I filled both tanks again 19.5 litres
That will do me fine 10 litres per 100km, last time I checked on similar run, it was more like 13 litres per 100km

I'd be happy with that.

Tony, with the 2.8 do I need to be checking the boost pressure and exhaust temp

i tried looking it up but to no avail.

butterfly valve? what is it, what does it do, where is it, and how do i remove it. and by removing it does it have any long term negative impacts on the engine?

i have the 98 2.8 td.

cheers!!!

Sorry mate, I missed this.
Boost pressure and exhaust temp tell you a lot about what's happening in your engine, I recommend fitting these gauges to any turbo diesel.

The blue arrow points to the butterfly housing. My understanding is it is used to partially block the inlet creating a low pressure and allowing the introduction of exhaust gases (via the EGR system) to the inlet. This is purely emmissions related. If you block the EGR (more power, better engine and turbo response, some report better economy) then the butterfly is redundent.
Removing the butterfly is easy, remove the housing indicated in the photo and have a look inside. You will see 2 small screws holding the butterfly plate to the shaft. Remove the screws and slide the plate out. Leave the shaft in place.
Long term, blocking the EGR will most likely extend the life of the engine. Removing all that carbon from going back through the engine has to be a good thing.

Thanks Tony, I remember back in my young days as an apprentice fitting pyros to trucks, and the drivers saying they drove off that as much as the taco.
Dam deisels have change, it was easy when it was a mechanical link from the pedal to the injector pump, now they but bloody wires every where, lol
