Huuuurfookingraaayyyyy! Changed out the leak off pipes and she sprang into life! Didn't even need the external primary pump, considering how cold it is this morning I think the glow plugs are working OK? Previous owner listed them as faulty.... didn't help that the lift tank was knackered and the leak off pipes? Weird how the leak effects some and not others? The excitement will be short lived.... Gearbox service, heavac repair, central locking, exhaust, brakes, radiator and water pump upgrade..... all fun, so twisted but I am looking forward to working on the old gal, might take her to Europe in the Summer if ready or we are not at War?
