[Healeys] Oil Pressure

[Roger Grace]

Michael - yes point taken; however your narrative didn't say what those BE journals looked like when you eventually stripped that engine  !
My manual says 7.25 litres capacity including the filter.Added another qrt of oil, so I now have 7.6 liters in my engine.Dip stick right on max. graduation markSame story yesterday after a long run with oil at about 175FYes do have an oil cooler but don't think that the cooler oil drains when I drain the pan.My thinking is that the capacity and style of the oil pan or gasket thickness does not matter as long as you fill up to the dip stick marks. The dip stick tube length is the reference that sets the correct internal oil level. Also the marks on the stickI note that there are 2 different sticks referenced in the Moss catalog.Mine is the straight one. So what gives ?Are there perhaps different sticks and tubes out there ?Mine looks stock but you never know ...Or maybe other cars also do this but unnoticed and ignored ....rg

Hi Roger, before panicking too much about your short lived zero pressure issue read through this article that I wrote about 14 years ago regarding oil pressure issues; it may set your mind at ease.https://www.netbug.net/blogmichael/2006/11/30/why-im-raising-the-suspension-and-fitting-a-sump-guard/

Oil coolerNormal running and idle OP is fine
Would welcome comments from more experienced listers.When oil is really hot - after a run after and after moderate hard braking (not panic stop) OP falls to zero for about 2-3 secs before recovering to normal - around 48 psi. Not noticed when oil is cold.

My thoughts:

Are there differences in the length of the pump input strainer assembly ?

Maybe should be using more oil with the extra oil cooler volume ? Maybe this dip stick is incorrect for this type of sump ?

This is bad for my BP - particularly when watching zero on gauge and waiting for it to pick up !!

Thank you
