Above you can see the donor engine with all the parts off. The leak was inside the basket area where the clutch plates are located. Behind this is the shaft that you can see above a large gear and then two seals. The leak from the oil seals. Both have been replaced and as my donor engine parts were from a lower mileage engine I used those parts also. The cover was removed and ring gear was changed. From putting all the parts back, the clutch plates was cleaned by Harry and reassembled back in August 2011. At the same time new plugs fitted and gapped at .6mm. New oil and engine oil filter fitted as well. I am hoping I have a clean patio when I park now.
