Thanks for all the advice,

Mark,the voltage with ignition on the voltage is at .5v,how can i prove the sensor without swapping parts?i cant find any info on how to test this sensor.

Shane,i have done a leak off test and they are all ok,hardly no difference in leakoff amount.Yes i will scope cam a crank and post it,the problem i was thinking with doing that is that the cam sensor only takes a reading off the inlet cam from what i can see,so the exhaust cam could be out but the cam a crank would be ok.

Thanks for the offer Sam, but im miles away in wales.

Thanks Lee
