I think telling the car it has fogs depends on the cars system, early cars with Lucas don't need telling but later cars with Pektron do, of course I maybe wrong
Found the vid but cant seem to copy a link, so Youtube search for MGTF cambelt change and pick the Rimmers one which includes the head gasket, if it opens at the start fast forward to 25m 15s in and you will get a clear picture and explanation.
Stick with it mate I did mine last year and was pulling my hair out, then it all fell into place and I wondered what I was fussing about. Check out the vid and there is at least one other on youtube, a picture is worth a 1000 words but a vid is priceless.
Good Luck
You might need to make the mountings pretty sturdy, probably better to the car than the bonnet. I was driving mine once at about 50/60 in reasonably heavy rain and noticed the rain going up the screen, when it was safe I turned the wipers off briefly and the airflow kept the screen clear. I know very little about aerodynamics but it suggests to me that there is quite a lot going on at the base of the screen hence I think anything flimsy might have a short lifespan.
personally i wouldn't these cars do get light on the front end at speed as too much air goes under the car instead of over it. TF's used for racing have large vents in the bonnet to combat this, blocking the vents will I think only make things worse.
Funnily I was looking on here Sun and saw a post with G and underneath "visitor" and I thought do we have visitors? if we do where's the tea and biscuits
Welcome, black, white, silver and a mirror, we will endeavour to bring some colour into your life. A TF tends to put colour in your cheeks, a spring in your step but accompanied by a pain in your wallet.
