Hi did you clean out all the breather system or just some of it?

Breathers had been previously cleaned out. Just noticed the small breather pipe had split.

The rubber bit from underneith the black breather box has fallen off

I don't blieve this was disturbed although I may be wrong. I think the plenum came off and went back on with the breather still attached....

EML does come on when ignition first turned on doesnt it?

Yep. EML was working fine but no fault codes

[quoteGlueing is not a good idea on the vac res. You never know whether the glue is blocking the inside of the union or not. I domt think they're that expensive to replace[/quote]

Agreed, and I'll be surprised if the glue's still holding but it was the best we could do. Given that the pipe was swinging loose at the start of the job I doubt this has changed anything TBH.

The SAI pump cutting out is probably coincidence, but easy enough to eliminate by unplugging the pump.

I did think of trying this but another thought overtook it and we never did. Might be worth a shot.

It certainly seems as if something the ECU does after a certain period of idling kills it dead. It runs OK under load, but 30 seconds of idling and it cuts as if the ignition has been chopped. No misfire, no noises under the engine bay, just stops dead.  

Possibly just the engine heating up enough before the crank sensor fails

Could be but wouldn't we have seen a fault code?

It is a wierd one.

Another thought. I suppose the engine management light hasn't been wired to the airbag light or something stupid to stop it bleating? Might be forth a paper clip test just to ensure it's OK and see if there is any clue stored?

All cleaned out

I would still realy clean the ICV.....just because a thought good one has been tried, is it known that this other one is ok or has the usual mechanics trick of adjusting the throttle stop been done on that engine.....hence ICV coul still be suspect.

When doing the paper clip test, do you get any flashing at all as it should at least indicate the 12 code for start and finish of fault sequence.

Mark the icv that is on the car is from my car and has got no faults at all,plus the icv that was on his car when he got to tidworth has just done 269miles on a run and is idling as sweet as the day it came out of the factory.we can rule out the icv.

Is it sorted yet mate,what did you find if it is.
Gary.

[andycuk71]

No not sorted still as bad as ever but have managed to replace the expansion tank and that cured the over pressurise and boiling straight off so top marks for that one Gary!!!!! so still aw\iting any further ideas guys....

[Kevin Wood]

I'd try a paperclip test just to prove the light is working, not wired up to airbag to disguise a problem, and to see if there are any stored codes in there.

Are the cam covers sorted?

Kevin

[Kevin Wood]

Just another thought. We did disturb the HT leads a bit so may be worth checking that they're secure in the coil pack if you can reach down there. I guess one could be sparking away and maybe causing some electrical interference?

Cam covers seem to be sorted thanks to your expert sealant and placement!!!!

Will try the HT leads on DIS pack and let you know
