Been running mine with the blanking plate in and made it run better seemed to have more power down low, I also got an extra half a kilometer to the liter. Mine has been in for a couple of weeks now with no adverse effects.
I have been told by a very reliable source that there should be an 8mm hole in the blanking plate? not 6 or 10 or 1/8th it has to be 8mm This very knowledgable person/persons were quite adament about it. the reason I was asking was because of the long trips to NT and Cape York that I will be doing very soon and I was worried that it might start to throw codes or whatever along the way.
Just letting you know what I was told to do by two mechanics????
I am going to try it but if the fuel consumption goes back up I will have a spare blanking plate to put back in again.
Where I put mine was above the water trap above the manifold,( I think its called a water trap anyway,) before the gas runs over the back of the motor and into the inlet manifold.
It looks to me to be a better place where the pipe comes out down low before it gos into the water trap, but no mechanic so not sure?
I do have the new inlet manifold fitted it was done on warrantee which was good. The truck only has 45000ks on it.
I am so confused its not funny as I am being told different things by different people and don't know who to believe or take notice of.
