Oil Pressure reading zero :S

[BristolSam16v]

Sensor failed? Won't read even if im driving around, was reading a bit earlier but then back to zero no matter how much I revved it, engine wasn't overheating and im guessing I would pretty quickly realise if the oil pump had gone?

Where is the oil pressure sensor located? hard to change etc?

Sensor is at the back of the block on the O/S, can get to it through the wheelarch with wheel off.
Check all your connections first.

aye.....would say the wires come off.

whilst on topic of oil pressure, what does yours read just as you start engine up before it gets warm.

clio 1.8 16v or williams :D

[Danlp6]

5 bar on startup. then when warm just over 1.

tbh...that depends on the oil used.


mine sits at bout 5 on start up, but drops to barely reading on the gauge wen warm. diff oil.diff readings

mines on 3 on the valver on startup! does that mean theres something not quite right?

[drsmith1979]

I'm with 2live, on start up when the oil is cold and viscous the oil pressure is really good, 5bar+ after its at runing temperature it drops to around 3bar+ when driving, and drops lower and lower on tick over as the engine gets warm and the oil starts to thin. was worried at first but its definately not the sender unit or sensors and the its simply down to te oil. going to change to silkolene from Guy at opie this time so wil see if that makes a difference.

is that the best oil to use then? what thickness is best for my valver?

[nyk]

5.5 to 6 bar on start up when cold.

Drops to around 3/4 when warm and general round town driving.

same as above as well drops to around 1-0 on tick over when warm.
