Just to update on my banjo bolt situation....
After a short hospital stay I finally got a chance to look into getting the old girl sorted and to my surprise when I looked at the smaller of the two banjo bolts, the one I took off the car didnt have the small filter in it, so I presume at some point its been changed and not with an OEM bolt.
Given the car ran fine, just going to run on that basis, so ordered a couple of HEL performance stainless steel ones and also ordered a couple of the large bolts from the LLL website, so thanks for those Matt it was very useful.
No excuses for me now!
