[QUOTE="pdailey, post: 943986, member: 9032"] Here is what my dad says. He is the zen master when it comes to creative stuff like this. [COLOR="Red"]Quite the project. Everything you are trying to do is doable in my optinion. Just complicated. No issue in the pumps running dry. As long as they are connected to the engine they will suck an oil mist out and that is enough. We do this with vacuum pumps. Take a look at the airplane industry for how they go dry sump. Not a perfect setup but will help. they use a check valve that is gravity sensitive. So if you dry sump the engine and have one section plumbed to this valve the bottom of it would just go back to the pan and the top would go to the valve cover. When you invert the check valve changes the inlet porting to the top of the valve cover and seals off the bottom line. We do many pumps with torque converter pumps integrated into the dry sump. take a look at this page. [url]http://www.daileyengineering.com/sp_other.htm[/url] Same scenario with the trans using the check valve. The only problem I see with these valves is they like to either one way or the other. I don't know the logistics when you are tipped at a serious angle. I would think it would stay to the bottom until actually rolled over. If you land on your side than the valve is horizontal and no gravity acting on the valve. Not sure what it will do. Also the oil tank for the dry sump needs to be addressed. I have been asked to help several crawlers with dry sumps but noone has stepped up. The issue with the tank is keeping the bottom of it full of oil and when you are at an angle the oil in the tank is at the same angle and allows air in the pickup. I think some kind of swinging oil tank would work kind of like hanging the tank from a ball joint. Not a simple task but if it was easy anyone could do it. Bill[/COLOR] [/QUOTE]
