I just changed the oil pan gasket on my 1998 Lincoln Navigator. It still leaks oil when running. The leak looks like it's coming from the top of the front 2nd bolt on the passenger side of the oil pan. What could it be? Oil sensor or what else if not the sensor. Thanks, Ted

clean around the oil pan gasket area well as some oil leaks are actually rocker cover gasket and filter leaks that run down the block and appear as pan leaks.. Check front crankshaft seal as the oil from there also appears as a pan leak

Only thing you can do is look for it. If its on the top or sidesof the engine it shouldnt be to hard to tell where its coming from. Most likely valve cover gaskets. If its on the bottom of the engine its most likely the oil pan gasket. Some vehicles when doing an oil change because of the oil filter location, oil will drip for awhile and make it look like it has a leak when it really doesnt. I would check teh valve cover gaskets, oil pan gasket and make sure your oil filter and plug are tight.

Thanks.

you need to find that leak, is the leak visible? if its not from radiator or the reservoir, the only other place I could think you can lose water is the head gasket. It happens to high miles and hard driver. 100k miles would likely be a head gasket. Leaking head gasket will also cause the engine temperature to rise and run super hot. antifreeze will leak through the head gasket down to your oil pan mixing oil and water. Check your oil by pulling the dip stick and see if you have oil mix with water; it will have a slimy looking colors, oil is light color and it should never be black. if it black than change your oil and inspect it afterward when the car has been running for while. when engine really hot cause the heat to effect the starter not to engage or start or engine is too hot to run. repairing head gasket could run anywere from 500-800 bucks.

TRANSMISSION LEAKS COME FROM TRANSMISSION OIL PAN GASKET LEAKING.OIL COOLERS LINES LEAKING.LEAKING AT TORQUE CONVERTER FRONT SEAL.TRANSMISSION SPEED SENSOR SEAL LEAKING.FRONT AXLE SEALS LEAKING AND LEAKING AT TRANSMISSION COOLING LINES TO RADIATOR.CHECK ALL YOU WILL FIND LEAK.IF YOU HAVE FAST LEAK OR PRESSURE LEAK.WITH CAR RUNNING IN PARK EMERGENCY BRAKE APPLIED LOOK UNDER CAR IF YOU SEE FLUID LEAKING OUT IN LARGE QUANITIES.COOLER LINES LEAKING OR TORQUE CONVERTER FRONT SEAL LEAKING.IF YOU HAVE SLOW LEAK THE LEAKS HAS TO BE AXLES SEALS OR PAN GASKET LEAKING OR VSS SENSOR SEAL LEAKING.

TRANSMISSION THERMOSTAT INSIDE TRANSMISSION ON VALVE BODY YOU HAVE A PRESSURE LEAK CHECK TRANSMISSION OIL COOLER LINES FITTING TO RADIATOR FOR LEAKS LOOK UNDER CAR WHILE IT RUNNING LOOK FOR FLUID LEAKS. YOU COULD A LEAKING TORQUE CONVERTER SEAL.

Sounds like a bad head gasket. This can destroy your engine. Get it checked out immediately!

sounds like u have a cracked oil pan, requires removal from engine and either welding or new pan estimate cost around $300 and up depending on location and if other damage
