T-18 Oil Pressure Off The Chart...

[JDM KE70]

hey guys,

 

My 1979 t-18 fitted with the stock 3tc with 155,000 kms on the clock. Serviced every 2 months or soo. :yes: Anyways the oil pressure has gone nuts when hot at random. :bash: I wanna top know if anyone has any idea about this problem..

 

Any help would be great before i pull my sump off and replace the pump. :dance:

 

cheers Nathan.

Too much or too little pressure? Have you got a manual gauge on it?

[styler]

The pump has an inbuilt bypass when pressure gets too high, can get jammed if pump is old.

The council won't like it, but you will have to take it upon yourself to train it and ensure it does not turn to the Dark Side.

is the guage shorting out?

 

if a sensor/guage throws up odd readings, first step....look into sensor/failures.

the pressure is high didnt think this would happen beening so old and all.. replaced 2 oil filters oil and oil pressure sensor already. its come good atm but not wanting it to happen again.

is the oil pump valve getting stuck the normal fault. has this happened to you?

If the gauge gets shorted out I believe it goes to max reading, so it could also be in the wiring anywhere from the gauge to the sender.

 

Hopefully a new sender unit sorted it out. I can't see the pump delivering more than 60 or 70psi a the most, and that is when cold.
