Fitted my oil pressure gauge today and I'd like to know what it should be reading at cold idle, warm idle and whilst under load.

Ta muchly in advance chaps

 

cvh cold idle 60psi warm idle 15-20psi under load 40psi. zvh cold idle 75psi warm idle 25psi under load 50psi.

 

My old fiesta used to be 70psi cold - 15-25psi idle - under load 40-45psi so around these sort of figures is right

 

Everything seems fine going of those figures except my warm idle which is around 5psi

 

very strange, so its basically got no pressure whilst idling, that can't be good.

 

Just been out in it and it was at 10psi when it was idling warm but sometimes the revs drop slightly and it goes right down to around 5psi.

To note though, the iscv is unplugged due to it idling at 2k when its connected. Also its a low comp bottom end if that makes any difference

 

Could be lower because of the compression but i can't be 100%.

 

is it mechanical or an electrical sender on the gauge?

 

Mechanical I think

 

does it have a tube direct from the oil pressure switch? or just a bit of wire?

if its mechanical, where are you taking the feed from? oil pressure switch at the back of the block? also the tube could be kinked causing low pressure

 

No its got a bit of wire going from the sender to the gauge, its on a T piece with the oil pressure switch in the block

 

its electrical then

possibly a dodger sender, i swapped from an electrical to a mechanical cos the sender was unreliable.
