[QUOTE="Tazza, post: 1316, member: 82"] I doubt the oil leak would be specifically the relief valve, i would guess it would be your control block. There are no less than 40 O rings inside it, unless it is annoying you i recommend not touching it. It isn't that hard to repair, but it really is a big job as you have to remove all your tube lines and linkages, its VERY messy. IF you do, remove the block and replace the seals for each section one at a time as to not mix your parts up. Also, note which stage sits where. I get all my seals from a place called A & B Seals at Slacks Creek, they had all of them in stock. ooh, get 90 duro hardness O rings, they handle the high temperatures alot better, and remember to lube all O rings before you install them to prevent pinching when tightening. I guessed you lived on the Gold Coast, as you dealt with Clark down the coast. I may take you up on the offer of the pressure tester, but i have a long way to go before i would need it. I am still repairing the engine out of the 743. Hopefully the hydraulics/hydrostatics are in good condition.... [/QUOTE]
