As title........

 

Or is there another way using an aftermarket sender unit?

 

Plan B is an aftermarket gauge but I really don't want to go down that route yet.

 

 

TIA

for the z?

Why can't you just get a new / 2nd hand one Rob?

Yes, for the Z

Well new is £80 is it? You could get an aftermarket setup for much less than that and a secondhand one might be as bad as mine.

 

 

 

TBH my stock gauge is playing up, this morning on the motorway it read a nice 60psi, stopping at the lights it went down to 0 and stayed there for a while. I stopped the engine and checked the oil and there was plenty in. It's Total 10w40 IIRC

 

One day I might really have no oil pressure and think the gauge is faulty, that's why I'm interested in an alternative if anybody found one.

Aftermarket is the only reliable one!

The problem is'nt the sender, its the gauge. The sender itself is fine, although the pin hole can get blocked up over time, but its the crappy gauge itself thats useless.

WHy don't you try an engine oil flush, can help sometimes?

Is it?

 

I never knew that - i always though it was the sender that went bad:p

I did an oil flush & change last weekend, seems worse now than before :(

Ditto!

The senders themselves seem pretty decent (although do bear in mind if its the original then its some 18yrs old or so and pressure hole is very small and can get clogged), but all of the stock Nissan gauges are useless.

 

You can see different temp, boost, oil and fuel readings just changing the clocks :smash:

Shocking!

 

The problem I'm having is after a motorway run to work, nothing high speed, 70-80 mph for about 8 miles happily reading about 50psi.

 

When I get off and stop at the lights it tends to read almost 0psi on tickover!

Even revving it up to 1500-2000rpm does not seem to fix it.

 

Strangely when I stop the engine, turn off ignition then restart it seems better. It must be gauge or sender really.

Took one of the sensors apart years ago to determine exactly what it is that fails in them, yes the hole can get blocked but that would worry me that the oil has not been changed very often, the unit fits in the turbo oil feed!!

 

The unit is part Nissan high tech and part school project, oil pressure acts on a small diaphram, there is a small linkage that connected between the diaphram and an acting swing arm.

 

The swing arm via the diaphram moves in relation to oil pressure,the upper part of the swing arm makes an electrical connection via a brass rubbing strip on to a variable resister that looks very similar to the insides of an old scaletrix hand controller.

 

The section of track where the rubbing strip is infrequently sitting such as when the oil pressure is high ( when cold or higher revs) remain in good condition and so the rubbing strip makes a good contact and the gauge shows high pressure.

 

Once the oil warms up and the pressure drop to normal or the revs are much lower the rubbing strip is now in a highly used area of the track and this is the worn part, hence a bad connection and a poor gauge reading.

 

There is nothing to do except replace it, I have no idea of the quality of e-bay items but they do go for around £35 which is probably a better idea than a second hand one, but a new Nissan one alays returns everything to normal.

 

The unit was used on the Nissan Patrol I think and most likely Almera Gt etc.

That makes a lot of sense Jeff. At this sort of age, it would be beneficial to replace.

 

I would have calibration concerns using an aftermarket sender with the stock gauge though. Would need to know the voltage,impedance, scale used between both to be sure.

 

The stock gauge cluster itself really is pretty naff though.

Mmm. yes the non Nissan ones may have issues who knows, I do not normally advocate the use of non Nissan parts but with economy in mind a non essential part llike this could be used.

 

Thinking about this I will purchase one and do some back to back testing against a new Nissan one and report the findings here in a week or so.

Another good bit of info there Jeff;) :dance:

mine has started doin this

mine has started doin this

 

would have to admit mine has always done it, but never worried too much as I've been warned about the gauges!! Plan to fit after market water temp, oil pessure and poss oil temp one day, only been saying that for six years ....... but, one day!!!

Jeff, are the oem oil pressure sender and the blanked hole for an extra tap off a 1/8"NPT fitting?
