Thanks guys for taking time out your day and emailing responses about our problem.
Our camshafts where fine.
It turns out our problem was injector washers where to thick. (Thanks to Aiden Birley for his post)
The 1st set of washers we used where just under 1mm thicker.
After reading Aiden post again we ordered 4 new washers from the dealer.
We where amazed that this was our problem.
Stupid us
We live and learn.
Thanks again for all your posts
