    Oil pressure indication has been intermittant. Usually when the engine is cold, I get a low pressure alarm that clears as the engine warms up. Recently, while driving in low temperatures and high wind, the alarm would only clear intermittantly. I suspect the sending unit because the engine only has 125,000 miles on it. How is the sender accessed for changeout without major disassembly. My Haynes manual doesn't discuss the oil sender but shows a picture of it with the power steering pumpm and AC compressor removed. Is there an easier way to reach the oil sending unit on the V6 engine?

You have either a weak oil pump or a faulty sensor check the leads on the oil sending unit and make sure they are not frayed. if they are not take it off and have it bench tested if it passes replace oil pump...please rate this

To pull the pan you will most likely have to pull the motor, and as for the lack of oil pressure at times, this happened to me and my engine eventually blew up. i did some reading and discovered that prior to 1989, bronco 2's had faulty cylinder heads that would crack inbetween the valve springs. sure enough this is what happened to my 88. so this may also be your problem if your pump and sensor check out.

Hook up a manual oil pressure guage and verify that it really has low oil pressure, if pressure is ok replace the sending unit , if it had no oil pressure the engine would be knocking by now, if the sender is not the fix then the next step is the oil pump.

Oil gauge goes to 80psi while I'm driving 70mph on highway, drops when I slow down. Why?


They are designed to change as the motor changes speed. If you have 80 lbs. of oil pressure than you have very good oil pressure in your engine. If it gets higher than 80, I would talk to service dept. at your local dealer.

Should the oil pressure gauge fluctuate with speed


The oil pressure guage will fluctuate with engine RPM. At idle it should be approximately 20 lbs./sq.in, at high revs about 50-60 lbs./sq.in. Hope this helps any concerns you may have. Good luck!

Low oil pressure after engine warms up in 94 blazer with 4.3


I have a 99 blazer and ever since I have owned it, it reads lower in pressure when idling, but will go up too 40 while driving. This is normal for the vehicle. If the pressure gets real low, and stays low, it means its time for an oil change.

As long as the pressure goes up when you give it gas, it is fine.

1995 buick century-oil light came on hour after oil change


Step 1-- replace the sending unit again. Step 2--if step 1 does not cure the problem--believe the light--have the oil pressure checked with a real pressure gauge temporarily installed inplace of the sending unit. Try to not run the engine at all until this is resolved. Usually a 1 min. run at idel with no oil pressure will not damage the engine. 5 min of idle will ruin it. 1 minute of highway speed 50 MPH cruise will destroy the bearings.

Oil pressure gage


At idle, at operating temp is there any ticking from top end of engine? Are there any knocking noises brom bottom end?
If no noises, change oil and add some Marvel oil to clean out galleys. If that dosent work, change oil pressure sendingf unit. Also, if you have a mechanical oil pressure gauge, hook it up and take a direct reading. Oil pressure (in any vehicle) at idle should NEVER be less than 15psi. Generally in 4.0 jeep engines it's never less than 30, with a high reading at driving rpm of about 40-60! (but, you did not mention what engine you have)
