I tried to take the cover off to look inside , Failed :(

I think I've got one Andy. Can't comment if its good or not but its not bad. It was a bit rattly for me so bought a new one stuck it on my 75v6, put the one from that on my sons ZS. I'm sure its sitting in a box in the parts bunker (was my little work shop).
The reason it rattles is the butterfly's arms should be pressed into cups.Quote:

The cups wear and the balls come out of the cups which allows the butterfly's to be loose
(and also the actuator arm just floats free).

Couldn't get the plate off so I drilled holes in it :D

Unless I can get a Guaranteed low mileage one, I might get a New one, The car is well worth it.
The rest of the car is in EGC.
Ah, Andy, all that lovely plastic! The modern car owners nightmare. Thank goodness for our largely all-metal 260 engines! Proper timing chains and all....
It is interesting, though, how some of these VIS units last forever while others wear rapidly. I (and the previous owner) went through three on my ZT180 in less than 100,000 miles. One recommended approach to minimising wear is to ensure you have an oil trap on the breather line. Yours certainly looks very oily and I'm told that the oil and other impurities mix themselves into a lovely grinding paste which speeds up the wear processes. I did put one of these on the 180, but ended up takling it off when it didn't seem to be trapping any oil. I'm about to put it on the 1275 engine in the MG1100 which definitely swallows lots of oil!
Andy - this is what my oil catch tank looked like. I attached it to the side of the battery box.
Cheers...
Thanks for the picture , I have heard if these but not seen one fitted.Quote:

Which accidentally also has a plastic manifold :)Quote:

[QUOTE=AndyG;148420]Oh, good old german quality, this rattling manifold ;)Quote:

I got very old manifolds from 1999 with excellent innards, also newer ones with less then 50.000 km which were gone.
Quick test: give it a good shake in all directions, there shouldn't be any sound
Decided to get a new one. Just need to get a catch tank now.Quote:

Bernard, Top marks for your intuition, great idea and a lot cheaper than an oil separator, just as a mater of interest how much oil does it collect in say 5kmls.
Not as much as you might think, I empty it maybe once a year. Probably a couple of tablespoons each time after 8-10kmls.Quote:

I have a few manifolds stripped down to investigate the cause of these failures and attempt to engineer a better job.
But so far have not come up with a cost viable solution.
i have one in my shed ready to gut out the internals once the one of my zs180 starts rattling.
when i bought mine 3 years ago and it was rattling so i took the VIS motors off and resoldered up the internal joints - tested they work with a borrowed tester off a member on the MG-Rover.org (LOWEdb i think his user id was) and its been fine ever since.
a member on the rover 75 forum (stocktake) has developed a self test vis motor, which is neat! Have you checked its not just the motors causing your issue rather than the location pegs?
i have researched this quite a bit and i have a report from land rover stating that the oil mist in the inlet manifold is not an issue, but they did not state what the cause was of it failing? typical!
I have not ran a catchment tank/filter and the jury is out on whether it actually helps, personal choice.
the variable inlet tract lengths that this system employs, only induces a minor torque increase at certain revs of the engine and for all the hassle and cost of replacing i'm just going to gut it. Then i wont have the worry of pieces of plastic getting into the engine either.
also on the mg-rover.org website there was 'sheddist' developing a metal and pin version but i have not seen any movement on it for years now but he may do at some point.
The oil catch tank helps stop oil contamination of the VIS motors which is known cause of failure with them.
I looked at what Sheddist had done but gather that it was not cost effective and have been unable to contact him.
As I spent a few years designing mechanisms, I thought that I might be able to come up with something. :ash
when i took out the VIS motors they have a button vent on the bottom of them which allows the oil in. I don't know why you just dont block it off it?
Letting the oil vapour through should lubricate those pivot points, which is good! It is only a problem when other particulates get it and create a grinding paste, but if you run a decent induction system that should never happen.
i dont suppose you got hold of a rover 800 cast version with double throttle bodies, whether that is any better i doubt it but it wont break!
Gutting it is OK for the higher revs but around town the fuel consumption increases dramatically, as my son will use it for around town (he walks to work) it is worth doing.Quote:

I did have the Rover 850 KV6 manifold at one time but didn't realise that there would be a future problem. :(
Inlet manifold fitted.
Great colour and Great Mk1 front end
Nice condition inside
MOT test Thursday

Very nice Andy :)
I spent the weekend trying to find a square 250/500ml tank with no luck,Quote:

I approve wholeheartedly. :applause
It may collapse though under the vacuum.
I thought you would like it :)Quote:

Did anyone investigate an inlet manifold similar to the 260 for the 180? or one like the Alfa Romeo 2.5 v6 engine (190 bhp)? seems as though something could be knocked up??
It is really a double manifold. one with the butterfly's closed and then open. so complicated :cenQuote:

Next job clean up the engine bay.
.
Got this oil cap and MG logo for my son's car as a xmas present.
