Yes done loads, i can do a Nasp K series without A/C in 1hr now Robert, the problem with the engines is the 1.6 and 1.8 are overbored and the footprint of the liner on the block is much smaller than the 1.4 and smaller engines, there is no coolant level warning either and the engine is lightly built and do not take overheating, if you abuse the coolant system at all you will either kill the block on bigger lumps by sinking the liners which then allows combustion gas in which creates a massive air lock in the poorly designed coolant pipe that runs from the block to the rad and destroys the whole engine by cooking the alloy until its like marsh mallow.
If you fit a coolant level sensor they are amazing little engines, performance is great too, a 1.6 bubble will destroy a 2.0 Audi coupe as my brother found out, he lost some money that day
And of course Robert, the price of parts is music to my ears, a brand new block for £200! they are cheap cheap cheap to run and go like stink, everyone should have a Kseries powered rover at some point just to see what Rover could have carried on doing if they hadnt of been raped!
