I made a pressure kit for under £2, 2 weeks ago. and, im no pro. will gladly explain how if interested? With a few pipes blocked off i found my leak? That is, my car is not standard and has an extra pipe from the WGFV to airbox, which was the leak. Why the extra pipe? i have no idea.

Also im no expert but could help you check a few of the usual suspects. A pressure test kit is what you realy need though.

I am about 20-30 mins from mansfield.

Let me know

Do the Jons have beers for the mobile boost leek detection unit?

[jon_91_s2]

Mansfield is not that far from us.
What's the beer supply like @ Johnny Boy's?

[jon_91_s2]

Dunno as never met him, but i have seen his car. White coupe with some very nice mods. Full rs2 spec i think.

I followed a link on this forum. To do, home made pressure testing kit. The thread showed a PVC tube with screw on top. A hole was made in the screw top to insert a inner tube valve. once all glued up and air tight.

Remove hose to MAF and replace with pressure kit. You will need to block up 2 hoses, which wasn't quite explained in the original thread, but has been if you search for my thread, about 2 weeks old. First hose to block is the hose from the intercooler to inlet, runs into a metal pipe that runs along the top of the engine, above the turbo. I used a spray can. The second is a crank case breather hose. Just below the first pipe you have blocked, a metal pipe from the side of the head, a small piece of rubber hose then another piece of metal hose into the the inlet hose to turbo. You will need to block up this rubber hose/pipe. This should have mostly sealed the system for you to start pressurizing. Use a bicycle pump to pressurize, i didn't exceed 1 bar.

I would suggest you remove the front bumper first as you will be able to check the intercooler and its piping. I all so did the markH mod at the same time. again find my thread it is shown in there, how this done.

Bumper mounting are behind the foglights and wheel arches

I went to B'n'Q to buy piping, but i could'nt find the one showed in thread, so this what i did.

I bought a drain pipe, piece of plastic without screw on top, approx 68mm across, really needs to be 75mm across, but i could find one, and about 20 cm long. It was white in colour, as i sit here i dont know the part No written on it. I then glued a spray can lid on to the drian pipe piece, drilled a hole in the can lid, cut a bicycle inner tube valve and glued it in.

I hope this helps? Sorry i can't post pictures. If you send me a PM of your mobile phone i can send you photos by picture phone. and or explain further from my ramblings.

Thanks
Martin.

I would take Bry up on this johnny. He and Andy p are the mobile boost detection team.

Bry, i think johnnys car is a 3b so may need to sort out a bung for that little pipe where we ha a slight problem on mine.
