Rabbi Posted May 16, 2005 Report Posted May 16, 2005 Heres the deal i have a car that has been sitting for about a year without oil in it. I drained the oil out to take the pan off and never got around to doing it. All the intake holes have been plugged,etc. But my main question is, Can leaving an engine sitting for 7-12 months without oil cause problems? I never started or even atempted to start it. im thinking of getting her going again soon, But dont want to mess with it if its a useless cause. Quote
White93z34 Posted May 16, 2005 Report Posted May 16, 2005 i'm asumeing the oil pan is damaged? what i'd do: take out all the spark plugs, fill each cyl with oil, then fill the car back up with oil and come back in a day or 2. *2 days later* try hand cranking the engine, if it spins hit the starter, oil should go everywhere, then put the plugs back in and fire it up.

1990lumina Posted May 16, 2005 Report Posted May 16, 2005 If no mositure got into the engine and caused corrosion, then you should be okay...however, some of the seals may be dried out and whatnot...its worth a try, what do you have to lose other then some time and a few quarts of oil? Quote

1990lumina Posted May 16, 2005 Report Posted May 16, 2005 Oh ok...I didn't read it correctly - thought the motor, and the rest of the car was sitting for that amount of time...sorry bout that lol - Jeff L. Quote
Rabbi Posted May 16, 2005 Author Report Posted May 16, 2005 hmm why would gaskets try out? wouldnt it just be the same as the motor sitting with oil for a year? since it would be all down i nthe pan hmm i dont know if i should even piss with this motor Quote

I had a 2.8 that sat for a good long while, and it didn't leak any oil when it was fired back up. Really, what do you have to lose? If you throw it out, it'll be just the same as if the motor fucks up anyway, might as well try it! Quote
5speedz34 Posted May 16, 2005 Report Posted May 16, 2005 I had a '92 3.4 and it sat for about 10 months. I changed the oil let it run for a few minutes and it was fine same with a 88 2.8. Honestly I wouldn't worry about it. Quote
Rabbi Posted May 16, 2005 Author Report Posted May 16, 2005 well i figured it wouldnt hurt it to sit like it has. But i wanted some more opinions before i put a good 10 hours into it to try to get her running. Quote
paulo57509 Posted May 16, 2005 Report Posted May 16, 2005 With letting an engine sit without oil for an extended length of time (7-12 months is really a long time), my concern would be that the oil pump can lose prime. Quote

If you're really worried about that, hold the gas to the floor (clear flood mode) and crank it for about 5-10 seconds. Quote

ShockTherapy Posted May 17, 2005 Report Posted May 17, 2005 they make a thingy you can put on a drill to spin the oil pump without running the motor, now i can't find the P/N, but it would be a helpful little gadget. Quote
Dan94Z34 Posted May 22, 2005 Report Posted May 22, 2005 hope you put sta-bil in the gas. gas looses is umph after sitting over 6 months. Quote
streetdreams Posted May 23, 2005 Report Posted May 23, 2005 my 2.8 GP sat thru a winter, summer and than winter again before I finally gave her the attention she deserved. and with that old oil in her, she fired right up last month I've put on a couple grand in mileage since than, trouble free till my coolant sensor popped outta the rad this morning. the 2.8 is a solid motor man,run for years if your patient Quote
