My oil prusser gage does not work

if your oil prusser HALF of the gauge leave you car ok - important use oil type 5 - 30 w

the ticking noise could be the rockers and the clearance may need to be checked and possibly adjusted.you should get the oil pressure checked with a gage to make sure its not an oil pressure problem.and start getting your oil changed on a regular basis as this is the most common problem for engine problems and failure and its the cheapest most cost effective maintenance.

One of four things is happening:

1. You are very low on oil, but probably you already checked that

2. The oil pump is not working, but the engine would not last long with no oil circulating.

3 The oil pressure sending unit is defective. This is a unit that send an electrical signal to the gage proportionate to the pressure it is measuring from the engine. If the pressure gage is bad then you get no signal and nothing is measured on the oil pressure gage. Also check the wires from the sending unit to make sure they are not frayed or broken.

4. The oil pressure gage is defective. Yes even new guages can be defective. Check the new gage to make sure is is operating properly. (external voltage check)


The only other possibility is that the engine is loosing lots of oil pressure due to excessive wear.

Good luck

if your engine is a 4 cyl, look on the drivers side of the back of the engine for a water temp sending unit,,,there are 2 units there, the top one is water, the bott one is oil pressure....easy fix ....luck to you

CHECK GAGES light (1) indicates a potential engine failure(low oil pressure, low coolant, coolant overheating) has occurred.
· Check gages and shut down engine. Gages should read as follows: Oil pressure 5 to 10 psi (34 to 69 kPa) at idle; Water Temp gage below 230 degrees (110 C).
· Check engine oil level (Para 2-11) if OIL PRESS gage indicates low reading. Check coolant level (Para 2-11) if Water Temp gage indicates high reading. Notify Unit Maintenance if levels are low.

If CHECK ENGINE light (2) is on, check engine oil pressure gage (3) and water temperature gage (4). If both indicate normal, proceed with mission and then notify Unit Maintenance. If either one does not indicate normal, stop engine immediately and notify Unit Maintenance

well im not sure what engine you got a 4 or 6 cyl but either way its in the front of the engine,if its a 4 cyl its on the right side of the engine in the front,if its a 6 cyl its more in the middle left of the engine,,,assuming you are looking for the oil dipstick

on the 1.3L 4 cyl 3.5 quarts 5W-30 1.8 L 6 cyl 3.5 quarts 5W-30

It's right next to the air filter and behind the radiator fan and to the right of the oil dipstick. The transmissions is black and the oils is yellow. If it's a manual, there's no dipstick there. If not check close to the forewall towards the back of the engine.

It could be worn camshaft bearings that is lowering your oil pressure. I had the same situation with my 2000 Jeep Cherokee 6 cyl. Changing the oil pressure sending unit did not make a difference. I used a higher viscosity oil and that prolonged the life for almost another year. If you put an oil pressure gauge on it and let it run at a prolonged normal temperature, it will give you a definite answer wheter or not the engine has low oil pressure. The real problem is finding the cause. Camshaft bearings are a likely source. According to the spec book, the I-6 engine had low oil pressure numbers to begin with.

Take it to a Dealer and have your gauges reset - you should also have your water pump replaced and you might as well have the Timing belt replaced also (usually at 80-90K)
