Nifty Posted September 1, 2008 Share Posted September 1, 2008 Can anyone tell me what the maximum oil pressure for a VHPD/R400 engine is please, i.e what pressure the relief valve is set at ? Keep off the straight and narrow 😬 Link to comment Share on other sites More sharing options...
Jason Plato Posted September 1, 2008 Share Posted September 1, 2008 std rover relief valve normally 3.9 bar spring with nice hot 90C oil , but cool oil will still produce readings of upto 8bar here is C7 TOP Taffia rear gunner Edited by - Dave Jackson on 1 Sep 2008 08:54:38 Link to comment Share on other sites More sharing options...
Nifty Posted September 1, 2008 Author Share Posted September 1, 2008 Cheers Dave, you've answered the question I should have asked but didn't ❗ (You Taffs can't be all bad ... or perhap you should be dunked in the Severn for sorcery ) The question was driven by the fact that I've changed from a 0 - 10 bar gauge to a 0 - 100 psi gauge and was surprised to see it so high up the scale at cold idle. 8 bar is 116 psi .. in fact 7 bar at 101.5 psi is off the scale ❗ Keep off the straight and narrow 😬 Edited by - Nifty on 1 Sep 2008 15:49:18 Link to comment Share on other sites More sharing options...
