cant really see any, just a bit of rippling and perhaps a touch of bubbles not anything clear where the water returns to the tank

i had the head gasket go on my last FRST and changed that myself, had it pressure tested and refaced etc,

i dunno i know it needs a new set of tappets so i might take it off the road for a couple weeks and get the head off etc

but before i do any1 else any advise?
