Well I got the thing throught the test today, but by more foul methods than fair. I disconnected the breather going to the induction manifold thus creating a massive air leak, then wound up the idle to make it run. It ran, but disgracefully, with NO power, BUT, the emissions went down to 0.2. Just glad they did not look under the bonnet! I don´t suggest anyone use this method of passing MOT´s, but my circumstances were somewhat unusual. Once I got round the corner, I put it all back to where it was. Next job, pull the head off and make a decision. Will be doing that this weekend when I go home.
Cheers.
