looks genuine,... assuming it’ll operate properly if pressure builds up ?

Thanks for youre help
Their Feedback looks good but, as I've said before, EBay can be a lottery.

Do not use silicon type sealer as it may damage the cat and llambda allegedly.Steve..

If you search the forum you will find a number of ways of testing for leaks.
Have you blocked the purge valve hose and checked the IACV steps at that point yet?

Thank you which yes I did and no changes ? I’ve taken the hose that goes off the IACV elbow at the bottom and upto the throttle body and put my finger over the top bit and it runs great, doesn’t rev up but still shows no stepsIf you search the forum you will find a number of ways of testing for leaks.

I would be very careful with the servo pipe and its manifold fitting. I am pretty sure neither is availbe new any longer.
I think you said whne you removed it the idle went up dramatically. This as expected and most likely indicates there is not a leak in that line, not 100% but pretty sure.
You need to eliminate possible leaks one at a time starting with the hoses, then the sensors, then mating surfaces.

Thank you I’ll have another play it’s difficult to say the least, I can hear a high pitched whooosh noise like a leak but just can’t put my finger on itI would be very careful with the servo pipe and its manifold fitting. I am pretty sure neither is availbe new any longer.

Unmetered air is never going to lead to smooth engine performance.Search carefully to locate it before adjusting anything.Good hunting.Steve..

I really would love to be able to answer your question, but I don't know how a blowing exhaust affects the IACV valve, I imagine it doesn't.
Stick with the genuine MPI manifold gasket. From a reputable seller (minispares) and make sure it goes on the right way round.
You need a specialist with a T4, someone who knows how it works and how to sort it out. There are a few out there, but not near you.
I Have a T4, but I'm a long way away !
With your throttle screw fully out, your stepper readings are going up, this is normal, the ECU is trying to get more air in, so it looks like it's working correctly, maybe not 100%, because it stays on "0" at other times.
Have you carefully checked all the wires going to the IACV valve ? remove the black tape at go back through the loom, test the continuity from the IACV plug to the pins on the plug to the ECU, when you get a connection, wiggle the wires near the plug to see if there are broken wires, it is a known problem.
