1999 Lincoln Navigator. This morning I noticed a few small oil spots on garage floor directly below the passenger side bumper. Does anyone have an idea what may cause that? This is the only leak of any type this vehicle has had. No visible signs of damage. Due to combat injuries I can't remain on my back long to further investigate, an can't really afford to take in repair shop, any ideas of what it might be?
Does your car have an engine oil cooler / transmission cooler , could that be where the oil is coming from ? Dont know if this applies to your engine ,
FORD = Head gasket failure
Ford dealers are repairing or replacing engines due to problems arising from a 1999 model-year revision to the 5.4-liter engine's head gasket. In defective units, the head gasket fails to seal variances in the engine block's surface, permitting oil seepage
Does not appear to be leaking from that area. It does not get driven over rough roads or long distances could something else be causing the leak?
When the oil pump is about to fail, would there be oil leaking? Just started vehicle, oil light came on, an gauge dropped to no pressure, an there was a constant whinning noise, will oil pump/bearing make noise if pump is failed?
The oil was down about 1/2 quart, but I knew that cause I was going to have oil changed this coming weekend. Do you know if it would be save to drive to garage as long as the valves were not "ticking" due to lack of oil circulation if the gauge/sensor is just bad? Engine did not over heat eaither
If oil is only down a pint , should be o.k . If its the switch / sensor thats leaking , usually only does it while engine running and under pressure . Could check if that is fault and how bad it leaks , but probably nothing major but better be safe rather than sorry .
I went out an started Navigator, an in about 30 seconds oil light went out an gauge started working again, then in a couple minutes they stopped again, this happened several times withing a 10 minute period. I have been trying to locate the position of the Oil sensor/sending unit, do you have any idea when it would be located? Thank youi
