    Sticky oil gauge ?

    Just getting some idea,s , RHD but shouldn't make any difference , NA6CE ,1991 Eunos Roadster
    Hopped in my car yesterday to go for a drive , check the oil levels , all good , clean perfect , Called in the servo to fuel up , ready for a decent drive and then noticed that the oil gauge was zero , no movement , (There's a sick feeling , been driving around for the last 20 minutes and not noticed it ) , Pulled over ,give it a rev , everything sounds OK ,oil on dipstick , pulled the wire off the sender unit a couple of times in case of dirty earth , Nothing , Drove it home , in the garage and carried on my day with the work truck.
    Today , had a think about it , Check the forums , Tried the earth out thing , Dead still , no movement , Started the car , sounds good as always , Give the Cluster a few taps while the car was idling and the needle slowly move to half , turned the car off and stayed still put , maybe moved a fraction down
    Which finally brings me to my question , Has anyone experienced sticky cluster gauges ? ,
    I,ve owned the car for 8 years, 177000km on the clock and never seen this before , Just trying to see if it,s common or not , i,ve seen the fuel one crap out and temp ones crap out but not oil , Usually the sender unit .
    Really does make you think twice about driving anywhere with a dicky pressure gauge , is it telling lies or do i really have issues , I do drive it hard , Rev limiter has been lifted due to Toda flywheel being so light and sick of hitting limiter in First and second .
    I may pull the sender off and get it checked , just trying to avoid pulling the cluster ( don,t want to break the cluster cover , $200.00 for another new one) .
    Any thoughts /Advise ?

    I've never had that experience, just a flickering gauge from a loose connection at the sender. Because the gauge responded when you tapped on the gauge leads me to believe that the issue is in the cluster.

    Sweet , sorta what i,m thinking , I've grabbed another sender unit from my work ( We do Mazda dismantling New and Used parts) and a external oil pressure gauge just to make sure engine,s OK , Confirm that's all ok and reluctantly pull the Cluster out , I forgot to mention it,s aftermarket JDM but all the backing is standard Mazda , Guess it will give me a excuse to put the Stainless surround and LED lights on i've had stashed for awhile , Not sure what the LHD Cluster covers are like but RHD one aren't cheap if i break it , It,s like new dash close up.jpg

    Probably answering my own question , but anyway; Well pulled the Cluster no worries there ,Question , Should the oil gauge be free floating like the Rev counter and water temp and Odometer ,ie, I give those a blow and they will rise and fall smoothly , the oil gauge is stiff and just stays where it is, It does use the full Mazda backing plate/gauge , Just a pretty cover plate , been in the car for the last 6 years

    It should move pretty easily, maybe not as easily as the tach, but not stiff. You think maybe it just needs a little lubrication?
