Open Question

95 Honda Passport 3.2L Oil Pressure

What is normal oil pressure at idle on this motor?
It has oil pressure gauge and it has 15 psi at idle currently.
When I rev it up pressure max out at 55-75 psi with 3000 RPM is this normal or not?

SOURCE: oil leaking on 95 honda accord ex

i would check the oil plug screw seal first before i would do the valve solenoid/pressure switch. also, if the oil plug screw seal is fine and tightly screwed in, it may just be the switch seal itself.

SOURCE: 1995 honda passport. When engine is cold oil

It could be that during the changing of the gaskets that some debris may have ended up in the oil passages in the heads slowing the flow of the returning oil. Or could be the oil pressure unit itself.

SOURCE: no oil pressure in my 1993 Honda Prelude 2.3 DOHC H23A1

my car did the same thing the problem was a $14 washer inside the oil filter fitting on the car you have to pull the filter conection off (from the car) bit of an *** around but pretty simple.

SOURCE: Where would I find the leak for oil around the oil

The unit it self is leaking, the housing it made of metal and the center where the wire is made of plastic and after a few years from the heat of the oil will crack the plastic, causing it to leak slow at first then get to the stage where it will drain the oil faster then you can make it around the block. Replace the unit as soon as you can, good luck and hope this helps.

High temp low oil pressure light comes on after driving for a few minutes, then off when engine at driving rpm. At stop light (idle or low rpm) light comes back on. Normal driving it goes out.

You need to find out why you have low oil pressure. It is normal that as engine rpm's increase, the oil pressure will rise- the oil pump is moving oil faster. Even though your light goes out, you could still have critically low oil pressure. There should be sufficient pressure at idle to keep the light off. The light will come on when your oil pressure is almost nil- I believe for some it's as low as 8 psi. Normally, oil pressure at idle is specified anywhere from 15 to 40 psi. You would have to check specifications for your Expedition. To verify oil pressure, hook up a mechanical gauge at the oil pressure sending unit on the engine block. Check with a local shop.

The causes run from easy, simple to budget busting ruin. Low oil level, wrong grade oil, real old oil, oil leaks, internal oil leaks, worn oil pump, worn crankshaft bearings. It was pretty common on older very high mileage cars to have a fluttering oil light at stops and idle. It was time for a rebuild, or time to look for another car.

Does anybody know what the oil pressure specs for the 2006 crown victoria lx 4.6L at idle and at normal operating temp? Mine is reading between 15 and 25 psi. Has 149,0000 on it.

15 seems low. Ford gives a spec of 40-70 psi with the engine speed @ 2500 rpm engine hot. Most cars I see are around the 25 psi @ idle. If your idle is lower than it should be it will make your pressure lower. This should be a direct reading on a good mechnical engine oil pressure gauge.

2001 tundra low oil pressure at idel engine warms up what does line on gauge repersent in lb how to fix or is it normal 90,000 miles obit always did since m

Well according to the owners manual, anything from low up to the last mark is normal. I think they mean anything from the low mark up half way is normal for idle.
If the gauge stays near L at idle and while driving, you could have low oil pressure or a gauge problem. A mechanic would check pressure with a mechanical gauge.
Normal for most engines is around 25-40 psi at idle and 30-60 psi when driving.

Oil light on after engine warm-up on idle

this means a mechanical gauge test is required to check actual pressure warm idling if low below 20 psi then the oil pressure pump relief is stuck open or engine bearing are worn

Oil pressure gauge reading

Normal is really any place in the middle of the gauge.
Depending on the age and condition of the engine, and the temp of the oil, oil pressure at idle should be at least 25-35 psi and at cruising speed between 40 and 60 psi.

Oil pump at idle is good when car is warming up, but after it get real warm after 20 miles of driving the idle oil presure is low about 15 lbs

  • This is normal. On your car, on a cold start the pressure will be around 75 PSI. After the engine warms an oil pressure of 15-20 PSI at idle is just what it should be. The oil pressure gauge should escalate when accelerating up a bit to. If your old school like me 15 PSI mean danger but tat Caddy is just fine.

I have been having intermittent problems with my '04 Trailblazer oil pressure gauge. Recently, when I am stopped at a light, or sitting idle, the oil pressure gauge drops to zero. Then, when I get...

It sounds like the oil pressure switch has failed. It is only an on/off switch that trips at about 15 - 17 PSI, the reading displayed on the dash is created by the computer based on the pressure switch being closed and the engine RPM.

I think you should have an accurate mechanical oil pressure test gauge installed in place of the oil sending unit and check to see what the actual oil pressure is. If it's 15 psi or so at an idle and about 35 psi or higher at 2500 rpm then your pressure is good and means you have some sort of issue between the sending unit and gauge. If the pressure is low, say below 10 or 5 psi at an idle with a warm engine and doesn't improve much at higher speeds then you actually do have low oil pressure, most likely due to worn bearings inside the engine. An accurate test gauge should tell the tale and help you figure out what is wrong. Hope this helps out a bit!

Truck has low oil pressure at idle no knocks just low pressure

The gauges on some of these weren't overly accurate so I would suggest having someone test the oil pressure with a mechanical test gauge temporarily installed in place of the oil pressure sending unit to see what the actual pressure really is with the engine fully warmed up at an idle [this is when the pressure would be at it's lowest point] If you have 15 psi or above then that's about normal. If you have less than 10 psi then that's getting fairly low and could be the result of worn internal bearings. If you have good oil pressure but your gauge reads very low then you might just have an inaccurate or faulty sending unit that isn't reporting the right pressure reading to the gauge. Once you have the actual pressure tested you'll know where to look next.
