Snagger Posted December 8, 2010 Share Posted December 8, 2010 Hi everyone. Could any of you who have oil pressure gauges please tell me what readings you get when the oil is fully warmed up (20 minutes of driving in this weather, for those without oil temperature gauges), both at idle and mission rpm?

western Posted December 8, 2010 Share Posted December 8, 2010 200tdi oil pressure engine warm at normal operating speeds 1.76 to 3.86 kgf/cm3 from defender workshop manual engine spec/info page Quote Link to comment Share on other sites More sharing options...
Snagger Posted December 8, 2010 Author Share Posted December 8, 2010 Thanks, Western. Those figures translate as 25-55psi, which my 12J got, and my Tdi has 55psi cold at all rpm, but when it reaches the last few moments of temperature gauge rise to the exact centre of the normal arc, where it stabilises, the pressure drops off quite a bit. it seems to be as the oilstat opens. I'm trying to find out what seems to be normal pressure, as I'm getting conflicting information about observed pressures rather than book figures.

western Posted December 8, 2010 Share Posted December 8, 2010 oil stat is marked up as 74degrees, got a old one here on the desk, my oil pressure drops to around 20psi when running/driving when fully warmed through on my well run in 200tdi with 400,000 plus on it's crank.

Paul H Posted December 10, 2010 Share Posted December 10, 2010 I only see about 18-20psi on my 300 tdi using a TIM gauge. Quote Link to comment Share on other sites More sharing options...
Snagger Posted December 10, 2010 Author Share Posted December 10, 2010 Well, that seems comforting - I'm getting about 15-20psi at idle and 37ish at higher rpm. I'd be grateful for more reports from others, but maybe these lower figures are not something to worry about and are typical of warm Tdis.
