OK here we go...
After still not having received my inlet manifold and being given countless promises I threatened that if I don't get it by Tuesday I will be demanding a refund as I am planning to go to Manc on the weekend to see Tom, Andy etc.
So I've been promised Tuesday or its a refund, fine. So in preparation I'll take off my old inlet manifold so when I get the newun I can just bolt it straight in.
After lots of swearing I had the manifold out and was taking a looksy...spotted straight away where the air leak was coming from, basically there is a panel on the bottom of it which had been 'sealed' on via the professional manor of mastik. So...someones had this off before!
This is where it gets a little worrying, I came up with the brilliant idea of resealing it so it at least stopped the air leaking and now I knew how the manifold came off, drive it for a couple of days and swap it out on Tuesday...brilliant...or so I thought.
Now before I prized open the professionally sealed lump of plastic infront of me I was expecting to see something like this...
But no, this is what I was greeted with...
Somethings missing....yeah that's it! the plastic rod which connects to the VIS motors and the valves to open and close them when several portions of beans are applied!
So that's the rattling explained....the valves were just free flowing...doing whatever they want and if I gave it any throttle air just forced them open...but sometimes not all of them...which explains why sometimes overtaking takes longer than it should!
Which makes me think that if the valves were not opening properly and controlled then the air had to find somewhere to go so it broke the seal and caused the whining!
Ahh....fun and games of rovernomics!
