mediabandit Posted July 23, 2007 Report Share Posted July 23, 2007 ok i took a little vid of it just so you guys know what i mean..... basicly, this just started hapenning, the oil pressure gauge goes way up to the 550mark and stays there. when i start the car up it flashes down to the bottom but then imediately goes back to the end. in the vid the car is off, then as i start it you can see the movement it makes. now i was wondering if that is a gauge issue or if maybe the oil sending unit is gone. in which case i will have to replace it tomorrow before i leave on my 1200mile road trip. if you guys need any other info just ask i will try and tell you anything you need. and it is a 1991 lumina z34. thanks in advance.

Pontiac6KSTEAWD Posted July 23, 2007 Report Share Posted July 23, 2007 You and your Metric guages.... Anyways, I would say to start with the Oil Sending unit. its probly the cheapest in a long line of repairs that could potentially correct the problem.

slick Posted July 23, 2007 Report Share Posted July 23, 2007 Definately the sending unit. A bad sending unit will either have it set at 0 or all the way up. Quote Link to comment Share on other sites More sharing options...

mediabandit Posted July 23, 2007 Author Report Share Posted July 23, 2007 ok so i can't get a sending unit today... and i am leaving on my trip at 4am tomorrow morning. so the question i have now is if it will be a big deal if i take the trip without replacing it first. what exactly will happen? anything? the oil is full and she doesn't leak or burn any, so is that sending unit just a indicator basically or what?

1990lumina Posted July 23, 2007 Report Share Posted July 23, 2007 You don't need an oil pressure sending unit at all..you just won't know if you have any oil pressure...and you won't be able to see a drop in pressure before it's too late (worst case scenerio)...The stock guage isn't very accurate anyways, but it's better then nothing.

mediabandit Posted July 23, 2007 Author Report Share Posted July 23, 2007 ok, that is what i though, should be no reason why there would be a problem with oil anyway, so i will just wait until i get back and he has it in stock, thanks.

True, thoguh I personally would want some type of warning system if I was about to leave on a long trip. You never know what could fail, and if caught on time you could avoid catastrophic engine failure. Again, I'm thinking worst case scenerio. In all honesty nothing will probably happen. I know my Millenia doesn't have a oil pressure guage (hell, all it has are tach, speedo, water temp and fuel - which sorta sucks)..it has a dummy light - but we all know once those lights start coming on it's probably too late lol.

slick Posted July 23, 2007 Report Share Posted July 23, 2007 I wouldn't worry about it until you get back. Quote Link to comment Share on other sites More sharing options...
GutlessSupreme Posted July 23, 2007 Report Share Posted July 23, 2007 I was pretty sure that the ECM cut fuel if under a certain oil pressure was detected... Quote Link to comment Share on other sites More sharing options...
1990lumina Posted July 23, 2007 Report Share Posted July 23, 2007 Well his is reading full pressure so I'd assume it wouldn't cut anything. Quote Link to comment Share on other sites More sharing options...
GutlessSupreme Posted July 23, 2007 Report Share Posted July 23, 2007 well yea, but I don't want him to think he won't be in trouble if it's bad, because who knows, he could turn it on tomorrow and maybe it'll decide it wants to read zero psi.

mediabandit Posted July 24, 2007 Author Report Share Posted July 24, 2007 well, i am gonna go anyway, i can't see anything happening. the car works great other then that gauge so i will risk it. i am not going to cancel my trip for something like that.
