Since having had the plenum off my Paj a wee while ago and discovering a monumental amount of coke in it, I had it into a garage and they've removed the plenum and cleaned it in an acid bath.

The bloke reckonned that it was flowing at about 1/2 capacity and had never seen anything quite like it.

He has also blanked the EGR circuit.

I'm picking it up tonight. I'll let you know how it goes...

Well, there is a difference but for the most part I find it difficult to quantify.

The two main things are...

The EGR delete means that it doesn't switch around idle making pulling away and coming to a full stop smoother and...
It's able to maintain motorway speeds much easier rather than having to drop a gear to get to the power.

I think the latter's down to the decoke.

I'll see how it goes and report back if there's anything else I notice.

Interesting. My local Mitsi say I don't need a decoke but I've ordered some BG 44K to give it a clean out and hopefully add a bit more power. I think I'll wait to hear more from you chaps about advantages before I go down the road of lifting my EGR valve out but stopping the dropping out at idle and at speed is a definite good thing!

Hows it all going on this ?

I can't add anything useful I'm afraid.... I've barely done a 100 miles since the MOT.

Interestingly would be nice to hear on an update as this might be something I would look into doing on the 3500 gdi I have on its way from japan

im about to do mine over the next few weeks as i have cleaned my spare inlet manifold and spare egr valves up ready,along with blanking plates made out of 3mm steel,i,m hoping for a couple of dry days as i need to change my coolant out,but whilst i,m in there i am going to walnut blast the inlet valves..then do an oil change ready for the coming cold weather Wink

so , i have done mine, just fitted a steel blank between the valve and inlet manifold, its been in for a few months now, engine performance seems to be a little perkier , no cels etc, BUT it definitely doesnt drive quite as well when its cold which isnt really a problem as it warms up very quickly, fuel economy , id say its still pretty bad , on a run im only getting very low 20's at best hard to say if its improved it may even be a bit worse, ive done a couple of oil changes and really wanted to pull the inlet and give it a clean, just havent had time when i havent needed the truck.
