[QUOTE="theNEWT, post: 94895, member: 7078"] Thanks Tazza. I should be able to change the seal without bother - I hope. I have removed the shroud and done the best clean up I can for the moment, there was a lot of crud everywhere. Next Ill bring in a high pressure cleaner before anything else. After the initial clean up the steel pipes do look a little dubious, the very bottom one has surface rust and some pitting. I'm in two minds, should I assume its the pump seal and not touch the pipes or should I remove the pipes one by one to be sure? Can the pump seal blow out that badly to lose oil that quickly? It does appear as if its been leaking for a while as the oil cooler and the radiator have a build up of gunk directly above the engine fan,,,,LHS from the back. I previously removed the cooler as I thought it might have been leaking, gave it a through cleaning and inspection, put it back before running it and it didnt leak at the cooler.....just spraying up from the oil dam in the shroud. When it went, the fluid loss was violent and immediate. I couldnt get the lift to drive down, the arms kept going up so I killed the engine. Restarted and managed to bring them down. [/QUOTE]
