Where is the oil pressure gauge in a 1990 Civic LX 4 door sedan?
Your 1990 Cadillac Sedan De Ville is not getting any pressure to the sensors and the fuel gauge and AC gauge isn't showing up?
I'd check the pressure pressure gauge and sender as well as the electrical connections and grounds. If you can't solve the problem that way, try an after-market oil pressure gauge, if for no other reason than to see if you really DO have an over-pressure condition. Note, if the oil pressure really is that high it's caused by a sticking regulator. You'll need to pull the pan and get into the regulator assembly to find…
Unfortunately no. Even the higher LX, EX and Si trims were non-vtec in 1990. Here in the US market, the first models to feature vtec were the 91 NSX, the 91 Integra GSR, and the 92 Civic Si. In Japan, there was a 1990 Civic that had vtec, the Civic SiR and Civic Special Edition. In Some other markets there was a similar model, the Vti/Vti-R.
I drive a 1990 Toyota Tercel and upon initial startup the oil pressure light goes on and off until the engine warms up. why?
No, the 1990 civic transmission is a cable operated clutch and the 1995 civic is a hydraulic operated clutch. So unless you rig up a hydraulic clutch system(Master cylinder, pedal, slave cylinder, lines...) it will not work. But a company called "Hasport" makes a bracket that has a cable attachment that operates the clutch engagement and disengagement.
