I have just under the bonnet of my megga for a general poke around and clean up (about two cans of carb cleaner) to try and see why this motor seems to be alot less powerful than my last 2.5.

I have been looking aty the multiram set up checked all the pipes etc and it all seems to be in order no spilt or ripped pipes but i can not see any parts of the multiram working at tick over or at high revs (i belive this i why i have a lack of power.

I have done a search on here on how to check the operation of it but still nothing seems to do anything my eml light is not  lite up but does take awhile to go out some times (about 2secs) and now and again breifly flickers does this mean anything :-?

maybe it needs turning on with a tech2 device which i dont have

can any one help???

Have a look at this thread.....it may be of help

cheers

[nigsey1600e]

got to pop out now but i will try the sucking part later on.

 they operate freely by hand so  like that thread says it might be a number things then? orings etc etc

i will pop the bonnet again later on

[Taxi_Driver]

Also be worth checking vacuum pipes are on the correct way round.....this seems to be a common prob

[nigsey1600e]

just been back under the bonnet and tried sucking the relavent pipe but still no movement of the multirams.

 does anybody have any pics of how the pipe work should be routed, just in case some one put mine back together wrongly

[TheBoy]

You need to suck on the actuator side of the soleniod....

[Taxi_Driver]

In looking for something else....i came across this by Mark.....this may help you also

Had a look at thread  that mark  posted very informative i will have a better look through my system tomorrow night and see how i get on cheers

[nigsey1600e]

hi again

just had my scuttle off again to check why my multiram system does not work and so far all seems to be ok, i am now at a loss with this,  so i my well have to take it to a garage would it be better to take it to my best local garage and try to explain what i think is wrong or am i better to take it vx.

or would any off you members with tech2 be willing to help to see if it is  even turned on

Do the multirams move freely if moved by hand?

Using a short length of vacuum pipe, can you actuate the multirams by sucking directly on the vacuum pipe going to actuator...

[nigsey1600e]

they do move freely by hand both the front and rear valves, i have tried taking off the thin white vac hose going to  the front actuator and sucking that hard makes the front valve move,

 i cannot see which hose goes to the rear one?   will try again tomorrow (my times very limited)

 what is the vacum tank is that the black box with the black and white thin pipes going to it on the front of the engine?

[TheBoy]

The rear is right at back of plenum, and has a short U shaped rubber hose between actuator and solenoid.

Does is suck through (ie split diaphram) or does it feel 'blocked'

[nigsey1600e]

so the rear actuator has a rubber hose rather than a thin plastic hose then because all i can see near the rear one is a sort of S shape of hoses  

but all them hoses do feel very stiff  i will  dig around the rear again tomoorow. cheers for your reponse THE BOY

[TheBoy]

Yes, rear is a very short U shaped rubber hose. It goes from actuator (just under 4 rubber hoses at rear of plenum to solenoid valve on right of plenum.

[nigsey1600e]

sorry for the late reply to my own thread.

I have checked the pipe on the rear multiram actuator by sucking  on the pipe with a lengh of thin vac hose and i can  now see the ram open and close so i know now that both diaphrams are ok,
 i have changed around the two pipes on the vacuum tank at the front of the engine as they seemed to be the wrong way round (one seemed too tight in its path and other to loose if you get what i mean) and they were twisted over.

so i am now hopeing it all works but i still can not see  the rams open when i rev the engine by hand, if it is still not working what other areas should i start checking
