5lb of oil pressure in me wifes rav 4,

It is sitting in oilville off I64. While in the mtns the radiator fan ate the radiator, and $458 later all is well. only on the wan home the oil light kept blinking on and off every 10 min or so. Stopped in Waynesboro and had it checked out. Good oil pressure, oil good and full. Drove another hour and the engine quit. waited 20 min started up drove to a gas station and there she still sits. 2004, w/80,000 miles. They are telling me the motor is shot. I am thinking of going back up and putting in the thick oil, engine rebuilder stuff and driving her home.

What are my options?

Oil pump $230 plus 6 hours labor to install. $777. and that is a gamble as most likely it is not the oil pump. Tow it home? $$$$ ARGH!!!!!!! it is not looking good for me to go fishing this weekend :(:mad:

Mmmm ,,,, that's rough. Sorry for your troubles...that's a lot of money for a gamble, I had a 1900 head gasket done in a Porsche one time, got three miles up the road and all the sudden black smoke everywhere, I called the mech. He basically told me there was no way of knowing if the cylinder sleeves had been damaged until the head gasket was done... Well a new motor and thirteen hours labor later she was running smooth again lol

First thing, if light was blinking how did they check oil pressure? If they used manual gauge and you had pressure don't make much sense it would come and go like that unless regulator in pump is messed up. Did it run hot when damage to radiator happened. Is it locked up or knocking when running?

I talked to a lot folks that had all kinds of ideas, My first feeling was the shop that pulled the radiator bumped or put something back wrong and this interstate towing shop was just a crook looking to swindle a woman. So I went up there, changed the oil to 15 w40 with a qt of lukus. I drove it around the parking lot and the oil light blinked a bit seemed to blink when I hit a little bump. Hmmmm Motor ran smooth no noise. So I drove it home from other side of Richmond. Oil pressure is fine I think my wife was just a victim of someone trying to make a buck. Something is still not ok though, it wants to cut off at idle.

Have it plug ed up to the computer that will tell ya. Don't try to be a mechanic these days with the cars we drive you will loose your religion.

Does it cut off when you cut the wheels hard? Did they disconnect the battery when they worked on it? If so the computer resets, if you have 80k on it and the sensors (especially throttle position sensor) is dirty and the computer compensates until total power loss then computer resets... Can of throttle body cleaner and scrub the butterfly will take care of it... If this is the case, don't ask how I learned this

either a loose wire on the oil sending unit or the oil sending unit itself has gone bad .....easy fix if you are a do it yourselfer....new unit...less than 40 bucks

Update, So I took it to the dealer, YES I know they cost but sometimes I do think they pinpoint the problem faster. SO $39.95 for sending unit and $106 labor.

I asked the check out person, Why is it 106 dollars to unscrew a sensor and screw a new one in, Me thinks 5 min max. he calls up the mechanic, he knew his stuff, step 1 check voltage, Hmmm not good, step 2 remove sending sensor, plug in mechanical gauge, check pressures, all OK, step 3, drive around over bumps see what light does, step 4, replace oil pressure sending sensor. step 5 drive around see if all's well. 1 hour labor.

Considering your first estimate that sounds like a happy ending.

They gotta make money... Sounds like a very reasonable estimate, glad you got it worked out... I had a gauge cluster in my 03 Silverado go bad, was $1000 by the time I replaced it paid labor and reset the odometer/hourmeter. Amazing what they can charge for plastic pieces.

The light came on again!!!!!!!!!!!!! Ahgr!!!!!!!!!!!!!!!! it has got to be so,ething loose, bumps make it blink. what next?

Sell it.:banghead

Computer shut off the motor with the bad sending unit. did that out of safety had your oil pump really gone bad. that is a good thing. just as much these days is electrical problems as mechanical part failure. All that electrical crap is for easier diagnosis when hooked to a computer. Won't help the average person. Makes You do just what You did. Take it to a dealer. Stuff too complicated for average man to work on now.

farm machinery is the same way. Mechanic brings a lap top to the field. Combines have big computer screens to monitor all operations and do self diagnosis on break downs so when you call the dealer, they can send the right parts out on the service call. That all works great until the diagnostic stuff fails due to use in heavy dust situations and a high vibration environment. A half a million dollar piece of machinery that is only worth the price of scrap metal without all that technology now. I guess they decided we could not farm without computers and they don't know how we used to do it. AND THEY ALWAYS TELL US THAT IT WAS FARMERS WHO TOLD THEM TO DESIGN THE STUPID CRAP. I always tell them to fire those farmers and talk to us. They need to make stuff more simple, not more complicated. I would pay more for simple.CF

I would assume they reset or cleared all the codes when the dealer had it hooked up to the computer. The owners manual may tell how to find any pending codes, or you can buy one that will tell you the current codes, and look them up on the webz... GL

Is it just me or am I the only one who sees the humor in your car loosing oil pressure in Oilville Va?

Ya know that was the first thing I said to my wife, OILVILLE! we are driving the car. light blinks constantly, never got a check engine light. It is electrical, the dealer had it ran it through the test, said it was sending unit. MY GUESS it is a loose connection somewhere, the wire to the sending unit is this micro fine thread thin stuff that disapears into one of those BLACK BOXes that do not come apart. OH the car does not show up on American computors as it is an import that origionally sold in Guam. I am not kidding when I say it came from UFUK Guam. It is written on the back of the car.

And there's your sign.
