BenjaminKirk Posted September 27, 2016 Share Posted September 27, 2016 So, I've just had the gallery gasket fixed on my HR. And I've got a nice healthy oil pressure once again. But I'm wondering, is it too healthy? On tickover the gauge reads 30psi which I believe to be normal, but at the slightest Rev, anywhere from 2-3k it can go up to 90psi, anything more than that and it'll reach over 100. (Under load that is, not in neutral) Is this normal? Is the relief valve supposed to open before you see pressures like that? Quote Link to comment Share on other sites More sharing options...
MITZ@CougarStore Posted September 27, 2016 Share Posted September 27, 2016 Were the gaskets damaged as I said to you on FB. Quote Link to comment Share on other sites More sharing options...
BenjaminKirk Posted September 27, 2016 Author Share Posted September 27, 2016 Yeah the gaskets were in bits. Replaced them now with the revised gaskets. Quote Link to comment Share on other sites More sharing options...

Are the pressures quoted cold or hot? cold would be perfectly normal, for hot it would be a little high, although not totally abnormal,what oil grade are you using?

BenjaminKirk Posted September 27, 2016 Author Share Posted September 27, 2016 This is hot. Using 5-30 fully synthetic oil. Quote Link to comment Share on other sites More sharing options...
Mark@Abbey m/s Posted September 27, 2016 Share Posted September 27, 2016 You need to check the oil pressure with another gauge to double check. Quote Link to comment Share on other sites More sharing options...
Dave6188 Posted September 28, 2016 Share Posted September 28, 2016 Mine is exactly the same after having the gallery gaskets changed, fully hot idle after a long run out around 30psi and revs to pressures similar to yours. Nothing to worry about I would imagine. My Mazda used to reach similar pressures under load so I presume it's normal. Quote Link to comment Share on other sites More sharing options...
