Parker's ServiceJunior diagnostic test kits are ideal to digitally measure pressure and capture min and max fluctuations in any hydraulic or pneumatic system. If that voltage is fluctuating, then you have either (a) a defective switch, or (b) an electrical short somewhere. cam and lifters are hughes. For some strange reason, sometimes the "check gage" light comes on and I noticed that oil pressure gauge in dash board is at 0. I'll take a video with my phone. After an engine is hot the oil pressure "reading" can be drastically reduced for multi weight oil or any oil for that matter. As no air cannot enter the line at the gauge end, the oil cannot "drain back"into the engine, much like if you draw liquid into a straw and then put your finger over the end of the straw the liquid cannot drain back out. Gauges not working are: alternator, fuel guage, speedometer, pyrometer, tacometer, and engine oil temperature. has the Cure for Harley oil pressure problems! Install a Harley oil pressure gauge.

Recently, due to the jitters, the needle on the gauge flipped completely around counter-clockwise and was stuck below the small pin it normally rested on. Never does the motor act like the lifters are bled down. The large illuminated digital local display shows the measured pressure and indicates the current status of the digital pressure gauge, even under poor lighting conditions. My oil pressure gage this morning is going from 0 to 4o. Was for proper mds/vvt and oil pump displacement systems to make sure work properly and when to. I noticed this recently. This is a discussion on Oil pressure needle bouncing around within the General Help forums, part of the LSx Technical Help Section category; My oil pressure gauge is bouncing around in a way that it had never done before. Our wide variety of gauge scales are available in different sizes and styles. Nice truck, runs great! Recently noticed oil pressure dropping very low at idle and the oil light comes on. Its the fluctuating idle speed that is making the engine oil pressure gauge to fluctuate in unison , meaning the oil pressure pump / sender unit & gauge are doing their job , if the idle was at a constant speed ( as it should be ) the engine oil pressure gauge would also be constant at idle. The pump spring is in the oil pump body. While driving, it read fine but would drop again at stop lights. I have checked the accessory relay and it seems to be working fine (according to test light). When I start the motor the Fuel Pressure Gauge fluctuates (bounces) between 6lbs and 9lbs, sometimes not a lot, but at other time it bounces quite a bit. The pressure will go up with engine RPM. Unless you have hooked up an external pressure gauge to the engine or used a code scanner with all the options, you won't know what your pressure is doing. I'm wondering if my oil pump is weak, or if I'm having problems with my distributor, which would tell me why the truck seems to miss a cylinder under hard acceleration too. You'll need to determine if the oil pressure is actually changing, or if the sending unit or gauge is lying to you. That doesn't have anything to do with the gauge, but some air in the signal line might reduce the amplitude of the fluctuation. It was middle of the green as usual for most of the flight except when it started a funny dance. Jeep Cherokee 1984-2001: Why is My Oil Light Flashing? Why is My Oil Light Flashing?

So perhaps the bearings themselves are seeing more pressure than the gauge, but it still does not explain how it can read so high at first. Its normal to have variation in engines and gauges,what is important is knowing what is "normal" for this particular engine by keeping mental track of pressures the engine usually makes. So instead of trying to second guess what the problem is (or what its not), buying/changing parts, hacking your oil filter apart, and what not, I would start with buying a good aftermarket oil pressure gauge (which you need), then see how bad your oil pressure fluctuates (or doesnt), and then go from there. when driving it will sit at about 60psi but will drop down to 30psi when sitting at a complete stop when the engine is hot.

A vacuum gauge shows the difference between outside atmospheric pressure and the amount of vacuum present in the intake manifold. 7 Troubleshooting Procedure for Faulty Oil Pressure Gauge Sensor. Conversely, narrow oil galleries (either by design or blockage) and high oil viscosity causes lower oil flow. The pressure gauge actuation system in the OMEGA™ General Service Gauge line is the standard 316 SS Bourdon tube system, which is engineered to precise tolerances for consistent repeatability and response to pressure fluctuations. The oil pressure gauge take off is at the back of the intake manifold, so (I'm guessing) the crank and cam bearings have been fed prior to oil reaching the gauge.
