Dave, thanks so much for the offers. I apologise for not getting back to you.
It turns out that the engine was technically speaking "shot". There was a crack in the block due to the shonky repairs and it was blowing into the water galleries once it was warm and the crack opened up.
I spoke with Phil at Triumph Rover Spares in SA and he informed me that I needed to get the matching Bosch setup engine and as such I have had one delivered. He was extremely helpful in several matters and I can highly recommend them if you need anything.
It's now a matter of having it fitted and hopefully more than a couple of weeks of happy motoring.
Again, thanks soooo much for the offers of advice and help guys.
Porchy
