yo880 Posted May 5, 2008 Share Posted May 5, 2008 Hi Guys, i am looking at installing an accusump system on my RB26DETT that i am installing in a datsun 240K (not quite a Z, but close ). I was looking at getting a 3 qt system with an electronic valve. i have done a search in the engine manuals i have, and also online, but i am unable to find out what pressure valve i should get. my options are: 20-25psi 35-40psi 55-60psi standard valve kit (pre-lube only) i have seen a pew mentions of some people using them here, so hopefully somebody can give me the magic answer i have a remote oil cooler and a remote oil filter adaptor, so i am hoping installation will not be too difficult. Any pics or details would be appreciated though Thanks guys Kent Quote Link to comment Share on other sites More sharing options...

Mike Rowe Posted May 18, 2008 Share Posted May 18, 2008 I have one for my RB26 Z - I havent fitted it yet, but from the research I have done, one of the quotes on this is: "The Accusump E.P.C Valve is offered at three different pressure settings. Each valve is designed to allow the Accusump to recharge when the engine's pressure is above the pressure setting and to discharge when it is below. When choosing the pressure setting that is right for your application it is important to consider you engine's oil pressure during normal conditions. You will want to choose an E.P.C valve setting that is below that normal engine pressure. This way when your engine is running normally the valve will allow your Accusump to accumulate oil pressure. Then when you engine drops below its normal pressure and the valve's pressure setting it will discharge its accumulated oil in the Accusump. If unsure of your engine's pressure it is best to choose the E.P.C valve with the lowest rating, the 20-25 psi valve " Quote Link to comment Share on other sites More sharing options...

RB26powered74zcar Posted May 18, 2008 Share Posted May 18, 2008 I still have my Accusump kit sitting on a shelf in my shop. I haven't got around to installing it yet because I wanted to wait until after my motor was fully broken in before install. I will dig into the install here shortly, and post pictures afterwards.. This is the kit I have (2qt.)> Quote Link to comment Share on other sites More sharing options...

ZT-R Posted September 12, 2013 Share Posted September 12, 2013 (edited) Would a checkvalve be necessary on the oil cooler in to engine line. Edited September 12, 2013 by ZT-R Quote Link to comment Share on other sites More sharing options...
