Cold Oil Pressure
My 2wd Cos runs 95psi oil pressure when cold and then runs at 40psi when up to operating temp. Is the pressure when cold to much? and if it is what can be causing it? Im taking my engine out next month and would like to sort it if it is to high.
Im using Silkolene Pro S 10-50 btw

Its always done it, and its doesnt stay there for long, maybe 3-4mins of driving thens drops to 50ish. Been doing abit more research and maybe its got the modified bypass valve spring thingy..?

It runs slightly higher oil pressure if I run Castrol RS ( or Edge ) 10W-60 but there is a reason for that to do with the oil molecules

Im suprised theres such a variation in the oil pressures we all get. Is that jus down to pump and type of oil used then? I would have thought we would all have similar figures unless its a knackered engine/pump...

Depnds upon oil temp, grade,bearing clearances, and releif valve spring force. Pressure itself isn't too important, it's theoil flow through the bearings. Pressure saps power, for example the DFV makes do with 40psi and revs to over 10k.
