Re: I would like to hook up an aftermarket oil pressure...
As some systems need input from oil pressure gauge,mount a tee fitting in the original hole where the sending unit is. attach the original sender to one side of the tee , the new sender for your gauge (or line for mechanical gauge) to the other side of the tee. Make sure that the line or wire is away from anything hot, and be careful going through the firewall that you don't drill through anything you need (like the heater core) Use a rubber grommet in the firewall hole to make sure sheet metal does not cut through the wire or line where it passes through.

If it is full of oil and the oil pressure light is not on. I would drive it. This engine also has a oil level sensor that may be bad making the light to be on. 10w30 is ok but always put in what it calls for next time.
the 1st thing to do is hook up a mechanical test gage and see what the pressure really is, the one used in the truck is electronic and u could have a sending unit problem, if the mechanical test gage show the same readings u will need a new oil pump, this assumes the engine doesn't have any bearing knock type noises
At this point I would strongly suggest that you have your mechanic hook a mechanical oil pressure guage to the engine and make absolutlely sure that the pressure is up to manufacturers standards. It may simply be a failing oil pressure sending unit, but, until you know, it could turn out a lot more expensive! Thank you, Dana
You probably recently had a new key made, and the Jeep ignition is chipped. The key has a sensor, and must be programmed to match the ignition. Some will start till you put it in gear, then it shuts off.
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
if pressure is higher than what it normally is after an oil change, you may have used the wrong grade of oil (too thick). Foam could be from overfilling, or from water in the oil (maybe antifreeze getting into the oil?).
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)
