Great stuff guys, tq.
As I said, not busting urgent fortunately, I'm going to give it some thought. The slot in the valence allows me to get a spanner on the rear bolt and I can get on the nut of the front one with a flexible drive. The problem is the length of the bolt will not allow me to remove it. I may take the grill off and cut a hole that is big enough to take a socket and then withdraw the bolt.
I'm going to Silverstone on Sunday so will be checking out similar age +8's and their owners!
I always fill my new oil filters before fitting and have never noticed a priming issue fortunately but thanks for the warning.
