RH Drive. 1) There is a large diameter corrugated silver hose from something mysterious at the bottom rear of the engine to something equally mysterious just behind and to the left of the radiator. What is it (the hose, that is), and does it matter if it is broken (mine is)? 2) There is a sudden new fluid leak from the engine / transmission, oily lightweight red to clear in colour, coming from somewhere behind the block and possibly closer to the LH side (and possibly not, I don't have a hoist), perhaps 25ml (1 fluid oz). Is there a 'most likely' candidate or should I get someone with a hoist to take a look? I looked on the Brickboard but I didn't find anything that matched what I was looking for. Is there an engine diagram somewhere that would help me to use the correct part descriptions?
