finmac Posted March 7, 2004 Share Posted March 7, 2004 Two questions: 1. Wheres the best place to break the pipework to get the old oil out? 2. Will one "break" suffice or do I need to break it in a couple of places? 3. How much oil to refill the system? cheers Finlay THE ONLY SE7EN IN THE OUTER HEBRIDES!!

chrisb Posted March 7, 2004 Share Posted March 7, 2004 Hi, My dry sump has a drain plug on the opposite side to the scavenge pump pipe, so I would use this! Failing that, I would remove the scavenge pump pipe and see what happens. I would imaging the second place to break into the system would be at the bottom of the dry sump tank. That should get most of the oil out. Not sure if this helps, as I haven't changed the oil since the dry sump kit was fitted. Chris Link to comment Share on other sites More sharing options...
Graham Perry Posted March 8, 2004 Share Posted March 8, 2004 Be careful re airlocks when you re-start for the first time as it is apparently very easy to run the bearings in only a few seconds if this occurs. There is lots of advice in the archive about restarting a dry sump engine after a complete oil change Link to comment Share on other sites More sharing options...
barry.h Posted March 8, 2004 Share Posted March 8, 2004 FWIW I tried a different approach at the weekend. I got the oil as hot as I could and then siphoned it from the dry sump tank. Saved having to break into the pipework and avoided airlocks. Probably lots of reasons why it was the wrong thing to do but....it worked a treat 😬 Barry Link to comment Share on other sites More sharing options...
Graham Perry Posted March 8, 2004 Share Posted March 8, 2004 Similarly to what Barry suggests I have drain plugs in the two low points on my system ie the sump and the bottom of the oil reservoir. This makes it a much less messy experience Link to comment Share on other sites More sharing options...
greg Posted March 8, 2004 Share Posted March 8, 2004 Either syphon or break at the bottom of the tank. Former way the least messy, latter is very messy! Engoy! Link to comment Share on other sites More sharing options...
finmac Posted March 8, 2004 Author Share Posted March 8, 2004 Cheers guys I take it that by syphoning then I cant get an airloack? If so Syphon sounds like a good bet - dont fancy wrecking my Roger King Engine! Forgive my ignorance but if I syphon whats in the tank then how much will be left in the engine/pump etc. i.e. what %age will I get out of the system? How much oil do I need to refill?

Graham Perry Posted March 9, 2004 Share Posted March 9, 2004 Can't accurately tell you that. On my system when I have drained the tank and the sump, there tends to be a small residue left in the hoses and near the pump, but it is so small an amount that I do not worry about it.

mikes Posted March 9, 2004 Share Posted March 9, 2004 I am also interested in this topic. Siphoning sounds like a good idea - I was having trouble working out how not to end up with (more!) oil all over the garage floor. Do you use some sort of cunning siphon gizmo - I don't fancy sucking on the end of a tube myself - a petrol mouthwash is bad enough !!

Taran Las Posted March 9, 2004 Share Posted March 9, 2004 I siphon my oil out of the dry sump tank using an old oil gun. Take the sump drain plug out and then siphon as much as I can out of the oil cooler. Followed by stripping and cleaning the tank. A right messy afair. Keeps me off the streets though 😬 Philip. D.
