Oil gauge
baghall - May 2nd, 2010 at 07:44 PM
Just fitted oil gauge to my 68 baja, however, it is not reading correctly. It is showing 60 PSI at idle but goes straight to the stop, 100 PSI, as
soon as I use throttle. Any help with why this happens would be good.
Thanks

Nah, don't think so. I tried connecions other way round and got nothing.

Either the sender doesn't match the gauge correctly or you have too much oil pressure from possibly a sticking pressure relief valve or too large oil
pump.

those are fairly high figures but is that on a stone cold engine?
pressure will always be considerably higher when its cold
even my old worn 1600s when cold idle at 50psi
the pressure releife valve should stop it going much higher though
like matt said the plunger might be stuck in its bore

I am very interested to hear what the cause is.
But as an industrial instrument technician in a previous life I will suggest you check/compare your pressure gauge against another pressure
measurement before tearing into the machine it is attached to.

Yeh know what you mean. I still have to drive it as it is my everyday driver. Idiot light is suddenly on permanantley (need to learn how to spell) and
I have all of a sudden lost all my dash lights. Just no time till weekend to chase up problem.

Any feedback?
Did you check for any blown fuses?

Do you have a 30mm pump? If so you need to drill the return passage on the oil relief valve to 8mm as its stock 5mm which is far to small for the GPM
of the 30mm pump.
check this.

Fit a mechanical gauge into the oil sender socket and get a reading from there first.
