I'm happy with those gaps, nothing will ever bind!
What prompted me to investigate was a slight tinny rattle from the front of the car when accelerating at higher revs. At first I thought pinking but no evidence at wot from low revs and high gear. I think and hope it's the cap chattering against the bonnet. I've moved the rad now and I'll stick some thin HD foam on the cap and go for a spin tomorrow, the roads are jammed now, to see if the noise has gone🤞
