Smoke after EGR valve removal

<< < (2/2)

Xtremeteam:

--- Quote from: "ian_s" ---iirc, the egr valve recycles hot gases into the engine when its cold to help it ignite the diesel better when the engine is cold, so maybe without the hot gasses the diesel isnt burning as it should for the first 20 seconds or so.

nope,the EGR is only in action when the engine is hot cos when it blleds the exhaust gasses intot he inlet manifold it actualy cools the incoming gases & dilutes the exhaust gases each time,

the EGR is always shut when it starts first thing due to it not being up to temp

Cal:
What are the symptoms for a knackered injector? Could that account for the rough running do you think?

Range Rover Blues:
Yes it could, try running a couple of bottle of red-ex through it, it could be sh**ted up and not spraying properly

Cal:
Hi RRB - I've been using Millers Power Plus for a while now. I was wondering if some sh*t might have got into the injectors from all the stuff coming out of the intercooler pipes - I didn't get time to flush out the intercooler and then was hoping to get an uprated one anyway...

Could it perhaps be a bit underfuelled, and burning a bit thin now that the intercooler will be cleaner?

Will book it in to the garage today anyway and warn my bank manager  :wink:
