Title: Big help please
Post by: megaomega123 on 19 July 2007, 18:26:32
Yesterday, got new exhaust (centre sections), had the plenum off to do breather box seals and broke the rear multiram.

Today, running very bad, when pulling off it putters with very little power this is right through the range at revs below 3000rpm. Once past 3000 it is ok. Would no rear multiram alone cause this? Please help, I don't want to do anything else to it as everytime I do something else happens which is worse than the original problem.  :'( :'( :'(

No air leak, it is just the connector. Forget the 3000rpm it is right through the revs.

So rephrase, just with the rear multiram not connected are these symptoms correct?

With rear multiram not working, power will be down, but not that drastic...

Multi ram now ruled out as i've swapped it for the air injection one. The exhaust that i had fitted yesterday is kinda ticking on driver's side, centre box. there was also  some water around the seams of the centre box. i took it back and was told to give it a couple of days to settle down  :D So could a faulty centre box cause the above issues?

multiram won't cause it to run bad.

Stick a latex glove on the tailpipe, and see how fast it inflates it!

You and your latex gloves lol. I'm beginning to think you have a fetish lol.  Shall I just let it go until it goes bang?

Done that, it was about 3 seconds until it went bang. I blipped the throttle lightly and the centre box is popping, sounds really bubbly and a bit rattly.

Nothing today, except swap the soleniod valve for the multiram with the one for the air injection. This was done after the problems to try to rectify, but no difference.

Yesterday, just sealed the breather box with latex glove rim until I get parts 2moro. Only major change is the exhaust.

Ok update on this. All seems well when cold, symptoms of missing appear after 10 minutes of driving and get progressively worse. I seem to have oil leaking on the passenger side at the back end of the manifold heat shield. Could this be the gasket leaking a bit (that i've just changed) and could this cause the missing once warm?

I am desperate  to get this sorted before Tuesday.

Sorry, you have to revisit that gasket.

Either, the gasket wasn't seated, too much or too little sealant, the small drain holes blocked, or blocked breathers.

You should be able to reuse that gasket if only done a week or so ago...

Cheers buddy. I am just about to remove that cover and redo it. I think it was probably too little sealant. Isn't it soooooo much quicker when you have done it before. Breathers were done thoroughly so I think a combo of sealant lack and bolts not tight enough, I don't have torque wrench, so just did finger tight and nipped them up  :(

Right, all done. Everything running fine at the moment. Just idling a little high, will clean icv again, probably full of shit like the plug wells were. The mistake i made was the cam cover bolts were no where near tight enough, I was over cautious  when it came to tightening them. Anyway, all seems well now although the centre box is still rough. I will return this on Monday, then it is cambelt Tuesday yeeehaaa.

Thanks very much for everybody who helped  :y
