Too right matey!!
Thin aluminium sheet rolled round it, and black high temperature sealant from my local Autofactors. Marvellous. I think I'm due under there again soon sadly......
It's just had its FOURTH water pump too! One when I got it 9 years ago, about 80,000 miles, one done by me - never again, one done by my mate just under a year ago, and one a month ago. I've bought cheap, and I've bought dear, doesn't make a jot of difference to this thing!!
Some radweld too, let's see how long it doesn't use coolant for this time. Have you got a stop watch?
