yep I tried splitting mine, took a long long time, lots of effort and it was totally destroyed, a dremil and a lot of cutting discs would do it, but to be honest for the time, effort, costs involved and the uncertainty of being able to reseal it properly imho its just not worth doing, buy a new one, then at least you get new vis as well.

Any further news on this?

I did buy a new one (date of manufacture 2008) and fitted it along with a catch tank to reduce the oil damage problem, but after a year and only a few thousand miles one of the VIS motors failed (very erratic indications on the LED array on the dash). Stripped and repaired one from the old manifold and have since rebuilt the new one as well as a spare.

It seems they are prone to failure where the microswitches are soldered to the PCB, probably due to a small amount of movement each time the switch is operated by the cam. I now superglue the switch to the PCB (making sure none enters the switch body) then solder it so there should be no future movement to break the joint.

nothing new in this steel replace? noone has tryed it?

[bigfella]

Sorry Mike, say it again?

Will have to post some pics of new manifold we have been trying need the trumpets machining, does away with vis so loose a little low down but then again its all about 5K+ on a V6. Not sure on road use as making for the race car.

We are trying to get round race regulations of standard throttle body but inlet is free so worth getting the tig out and seeing what can be done, as long as runs on stock ecu and gives a few more horses we will be well happy.

Any more news on this? Hopefully if Lawrence cracks the VIS motor issue it could render the plenum service free!

How is the plenum bonded together assuming its on a job that can be eased with heat, considering where it sits on the engine Im guessing not.

Has anyone heard anything from Sheddist?

[bigfella]

I did PM him but haven't got a reply yet.

For now a new plenum will be going on mine on saturday.

I've PM'd him about a clutch kit as well (as am in need of one urgently) but no reply yet... guess he's very busy at the moment

[bigfella]

Yeah I agree on that one. I'm happy to be patient, its just my car isn't!

Hi all
I also have a rattly inlet manifold on my zs180. I had it replaced at 52k, this one has done approx 31k and now sounds rough. I also get a lot of blue smoke from the exhaust on start up which lasts about 1 minute. Could anyone tell me if this is related to the inlet manifold please.

[markzo]

any news?

Hello Sheddist,

I've read you KV6 Vis-modification and realy like the beautifull steel arm you've designed.
Can you please ship one for me to Holland,

(I'll pay you in advance,if you tell me what are the costst(incl post&pakkage) and where the payment must go to.

Will you please let me know if you've recieved this E-mail?
I've tried to send you an E-mail earlier,but I'm affraid that they've lost somewhere.


Thnx

Hayo Kloos

With respect to exchange plenums. This is something I do not have the time for, also this carries some risk as what if on splitting, the cover moulding is broken or it will not seal etc. If I cannot fix it or there is a delay, then you car cannot be driven. Not a responsibility I am prepared to take. Perhaps someone on here has the inclination and time to take this on.

So, what is proposed is this:
Order an arm. This will be assembled and a shipping date given - Car is OK to drive with a rattly plenum.

As with clutch kits, you will be notified when an arm is available and payment will be requested. Not before.

Hopefully you will be able to split the plenum, replace the arm and seal it up again- Perhaps plenum splitting and resealing techniques will form a good thread on here.

If you are unsuccessful in splitting and resealing your plenum then you can return the arm for a £47 refund.

[bigfella]

Probably not good to have your address on show there mate.

I know exactly where your ZS/ZT is now and I shall be coming to take your wheels!

Hi All, Just got myself a Rover 75 with a knackered manifold. Are these kits to repair still available?

[smilerbaker]

they where never available

[Lates]

I have a spare manifold, still boxed, never opened. £400 collect only if anybody is interested.

You may have seen it already on the ZT 75 forum but a old thread has been updated saying patent pending on a solution to the awful Kv6 plenum. It claims 25bhp increase too. Mines rattling and may gut it over Christmas in the hope this kit eventually becomes available.
