Trk says oil pressure low turn off engine just changed oil 9 day a. added i qt.oil .now light back on.it is full of oil

The oil light does not indicate the car is low on oil (based on your discription) it indicates the oil pressure is low, the no start is most likely due to this low pressure and the fuel pump has been cut off to prevent damage to the engine from low oil pressure. Please have a shop locate the cause of the low oil pressure warning and repair it as needed. It could be a false light or a real one, which means if you drove it very far you may have damaged the engines bearings.

check level after adding 4.5qts and running engine until the oil pressure light goes out (about 30 sec) then top off with another half a qt if low on the dipstick please rate

This fix works for 2.7L engine. Worth having your mechanic look at.

Answer
NO: 08-36-99
SUBJECT: Engine Oil Pressure Light Flicker
DATE: Oct. 15, 1999
OVERVIEW:
This bulletin involves adding a terminal/wire/vent to the oil pressure switch connector.

NOTE: THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH A 2.7L ENGINE.

SYMPTOM/CONDITION:
With a hot engine the oil pressure light may be on or flicker on at idle.

DIAGNOSIS:
Verify engine oil pressure as described on page 9-21 of the 1999 Concorde/Intrepid/LHS/300M service manual (Publication No. 81-270-9140). If engine oil pressure is within specification perform the Repair Procedure.

PARTS REQUIRED:
Qty Part No. Description
1 05017800AA Wire Terminal/Vent


REPAIR PROCEDURE:
Raise vehicle on a suitable hoist.
Remove engine oil pressure switch connector from switch.
Remove sealing dart from the empty cavity at the rear of the connector.
Pull terminal locking ring outward from front (switch) side of connector to gain access to terminal locking tabs.
Install wire terminal/vent, p/n 05017800AA, in place of the removed sealing dart. Slide locking ring back into place.
Attach the connector back on the oil pressure switch.
Spot tape the wire/vent to follow the harness towards the top of the engine compartment.

These lights need to be reset manually. Try turn the key to ON (do not start) then pump the gas pedal 3 times.

you have low oil pressure, so adding oil will not cure the light, if the engine is knocking u have damaged the engine bearings and it will need to be torn down and rebuilt.

The check engine light doesn't monitor those things, it's an emissions warning. monitors a host of things that are emissions related. You need to have it checked by a technician. The most common cause is a loose (or defective) gas cap. Make sure it clicks when you fill up. As for being 1/4 qt low on oil, don't add that small of an amount. Only add if it's a full quart low. If you check it soon after the engine has been running it'll show low because there's still a lot of oil upstairs in the engine. The dipstick measures what's down low in the oil pan. Also don't add anything to the radiator; only add to the overflow jar. It's marked high and low; those are actually temperature dependent marks, it should be at the high mark when the engine is warm and low when the engine is cold. Coolant expands and contracts with temperature. Don't add straight H2O either; that should be 50-50 coolant/water. They'll do that when you get the oil changed.

most only take 5 qt put in 4 and check the dip stick if it is on full run the engine for a min and let it stand for a bit recheck and add what you need to full mark

Dear number601513: DANGER!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Adding oil is not going to make the oil pressure build up by adding more. The system is slightly more than a 4 qt system with an oil filter change. By adding oil, you raise the levels in the engine to areas where it is not designed to collect. Consequently, it is prone to leaking and can smoke by picking up oil through the pcv.
The fuel pump has NO relationship to it's oil pressure. The only relationship would be through providing enough fuel to power the engine speed above 600 RPM which would and should be more than adequate speed to drive the oil pump. The oil pump on the VG-30 is located at the front of the engine and is the last component which is installed prior to to installing the timing belt gear. The pump is crank shaft driven, so it is a positive drive unit and not very prone to failure. The oil pickup tube which is bolted to the bottom of the pump, is sealed by an "O" ring. This is a probable place for it to loose prime. The screen at the bottom of the pick up tube could be full of sludge which limits the flow of oil, thus keeping the oil pressure dangerously low. One suggestion prior to condemning the engine oil pressure, is to do a mechanical oil pressure test. You can remove the oil pressure sending unit and screw a mechanical oil pressure guage in it's place. The threads are not metric, but NPT tapered design. You can buy mechanical oil pressure gauge kits relitavely cheap and make a test tool with one. Due to the fact that the oil pressure gauge is electric, they can give misleading readings. If your readings are down in the 8-10 PSI area @ idle this is bare minimum, when you raise the engine speed, the oil pressure should reach 40-60 PSI. Make sure you bleed the air out ot the oil line going to the gauge beause "AIR" compresses and will give you a false reading.
I hope this is informative. Good luck.

could be that the screen in the oil pan where the oil is taken up is clogged. not certain--maybe oil change?

Nowdays 1 Qt. in 3000 miles, really isn't that bad, even some new vehicles claim that's normal. I know with my current vehicles, both at approx. 150,000-160,000 miles, they won't use any for first while after an oil change, but then after mileage starts adding up again, they start to use a little, approx.I Qt, every 1000 miles or so, until it's changed again. I've switched to the high mileage oil, just for piece of mind, as they say it revives seals, and has added protection for the higher mileage engines.This time around I'm thinking of adding "Lucas" & see how it works, as I've heard some pretty good reports on it, just to see if it will prolong that oil breakdown, at mid change.
