oil pressure for vp

[COMMY VP 666]

hey i have looked around and im trying to find out what oil pressure my vp should be. does anyone know?

also my oil light keeps coming on for no reason,

thanks for the help

[delcowizzid]

should be at least 40 psi or more when idling mine goes off the guage 80+psi when driving

[COMMY VP 666]

hey thanks mate, by any chance do you know/any one know why my oil pressure light keeps coming on, i have good and right amount of oil?

[delcowizzid]

switch may be just getting stuffed if you are showing good pressure on the guage did you fit a T-peice for both guage and pressure switch like i have

[TUF UTE]

doesnt sound right mate.. what brand gauge


my vp v6 with autometer gauge was about 15 at idle and 50 under load from 3 year ago memory



bring ya car to my place tomoz and ill fit the gauge dude

[delcowizzid]

i have a good quility quage with copper feed pipe into the cabin 15 psi at idle is low as so is 50 at load

lol yeah thats bad oil pressure

As for OP the problem may be the factory wire on the factory sensor coming losse so light will flicker on occasionally check the connection is clean and tight

hey i got my air/fuel gauge and volt gauge but cos i dont have the t-piece i didnt bother taking it out or doing anything with the oil.

not the gauges dont know what it is

Which light are you talking about the one on the cluster?

[delcowizzid]

so you havnt fitted the oil guage yet.you maybe loosing pressure if the light is coming on then.or the wire could be shorting out somewhere get the guage hooked up.

[COMMY VP 666]

nah the gauge isnt fitted yet, need a t-piece first. but it will help trouble shoot. yeah the oil light on the cluster keeps coming up

also just had a look should there be oil on the lil connection part

e.g the cable connection to the sender

[delcowizzid]

nope if its coming from the sensor the sensor is poked they leak after a while the vn ones were bad for it so as long as its not oil thats leaked from above ide say its leaking.you can just put the guage in without the T-peice but i allways recommend both as then you get the light show up on the dash to warn you of imminant damage as you cant allways watch the guage.and you get backup fuel pump supply voltage should anything happen to the regular fuel electrics as well.

[Pub247]

no clean it up so it gets a good connection

[delcowizzid]

plus i have seen them leak quite bad and still work so dont just think the sensor is dead and drive it only to find out you have no oil pressure and ruin the engine

it wont trigger the light from no connection only from shorting to earth

[Pub247]

so your saying if its not connected the light wont come on?

[delcowizzid]

yip as the sensor earths the wire to the block to turn the light on

[Pub247]

o assumed the light would come on ive never checked beside having a pressure gauge in instead. Might test that one tomorrow to see if your right even though you likely are

[delcowizzid]

yip 2 fat wires for fuel pump one skinny blue i think it is for oil pressure light. power from ignition to light on dash then out to sensor to switch the light on,

[COMMY VP 666]

so does just about everyone agree my oil pressure should be around

idle 40 PSI , and generally around 80psi

[delcowizzid]

something close to that i cant remember the exact figures its meant to be off the top of my head

[delcowizzid]

thanks to immortalty's thread factory pressure relief valve spring should be set for at least 60psi pressure before it pops open.they do sag over the years causing lower pressure.
