2006 Ford Escape oil pan is sweating, is it the gasket or is it the pan?

The mechanic said the oil pan is sweating and if I don't get it fixed it will make it porous? How can oil make it porous when oil is a lubricant? I need to top it up with oil every 1000 km or so. I am using synthetic oil. As well the mechanic said my front deferential are leaking oil as well. Is this the same kind of oil or is it automatic transmission oil. I put a cardboard under the vehicle and there are at least 4 to 6 drips every day. The oil spots are black not red. Is this a costly fix on both? Or is the mechanic trying to drum up a job?
Thanks Carina

My car has 134000 miles.

Experienced mechanics share their insights in answering this question :
Well I’m not sure about the mechanic’s use of terms. If the oil pan is "sweating" oil, then that would dictate that the oil pan is already porous. It’s not an everyday thing to happen but I have seen it a time or two. It generally happens in regions that have harsh winters and lots of road salts are used. The oil pan rusts through and begins to seep, or sweat, oil. Without seeing myself, I really can’t say whether it’s the pan itself or just the gasket. Either way, the oil pan has to be removed to replace the gasket. So if it actually turned out to be a leaking pan, it’s just the cost of the replacement oil pan.added to the repair. The labor is no different.
Differentials generally use gear oil of different weights depending on the application. Diff fluid is basically a very thick oil so it would generally appear as dirty oil on the ground if it’s leaking.

When the oil pan is warped, and the gasket has failed, your biggest clue will be an oil leak. You may also notice: Low Oil Level – Oil leaks are often difficult to locate, making a leak from the oil pan gasket almost impossible to find. A lower than usual oil level is a sure sign that there is an oil leak.
Generally speaking a good gasket does not need any sealant. But in most cases a sump can be fitted with sealant rather than a gasket. Use what you`ve got, and if it`s good quality materials and work you shouldn`t have a problem.
It`s a fine smear of oil, not a leak as such. It`s not something to worry about, unless it develops into a more serious leak.
Have you noticed that your engine is sweating oil? Then know that this is not always a bad sign. Heavily loaded cars/motorcycles are allowed to sweat a little bit of engine oil on their own. An old car often suffers from oil sweating, this is quite normal as long as it is not extreme.
A small oil pan gasket or valve cover leak shouldn`t prevent you from driving as long you check your oil level frequently and add more if needed. However, an oil leak caused by a punctured oil pan or other major engine damage will usually require your car to be towed.
Nitrile (Buna N) – This type of rubber offers very good oil resistance and can be used for a good variety of refined oils. Nitrile is the most commonly used material for sealing oil. It is also available as a Cork and Nitrile combination.
It`s a good idea to use silicone at all the mating points in the corners. Moroso does suggest that a dab of silicone at the corners when using Moroso gaskets can help guard against leaks in sensitive areas.
3M High Temp Silicone Gasket sealer can be used on intake manifolds, oil and transmission pans, timing chain covers, thermostat housings, and valve covers.
Sweat Can Cause Cracks and Stains in Your Car Seat

While the material is better at preventing stains, it needs to be cleaned and conditioned with particular products every few months.

Blue smoke from the exhaust: Bluish smoke can indicate your car is burning oil during the combustion cycle. Burning oil smell: A thick burning oil smell could mean oil is seeping onto hot engine parts. Frequent low oil light warnings: Regular low oil warnings can indicate excessive oil consumption or a car burning oil.
While there is a wide range in how much people sweat, in general the average person sweats between 0.5-2 liters an hour during physical activity. But according to some studies, people may lose a minimum of 3 liters a day, even without moving around all that much. How much you sweat depends on various factors.
While there are some oil leaks that can only be fixed by expensive repairs, most can be done in your garage or driveway rather inexpensively. The only thing you will need is a car jack, jack stands, torque wrench, and some special additives or replacement parts (something like a new oil pan).
The gasket is probably the most common cause of oil leaks, especially in older vehicles or vehicles that are used frequently & have a high number of miles. The gasket is a seal that joins the head two metal parts of the engine, such as the between the block and the head(s) as well as the engine block and the oil pan.
A punctured oil pan is a serious issue and can leave your engine without any oil. The potential for engine damage under these circumstances is much higher than with a slow oil leak from a gasket.
“When the weather is warmer, our bodies produce more sweat to help cool the skin down,” explains Marisa Garshick, a board-certified dermatologist in New York City. What`s more: “Heat and humidity can trigger our sebaceous glands to produce more oil,” Garshick says.

lost all oil pressure, replaced the oil pump, low oil sensor, oil pressure sensor, oil pan gasket,
ANSWER : The fuel pump will not stay on if you loose oil pressure. This is why it is shutting off. The loss of oil pressure may be from bad crankshaft bearings or camshaft bearings. The engine oil pan should be removed and the oil pump needs to be checked to ensure that you put in the pick up tube seal to the pump and connected the pump to the block. Then remove at least one main bearing cap and inspect the bearings for excessive wear and crankshaft damage. If you need some help with this, consider YourMechanic, as a certified technician can help diagnose the issue with your oil pressure firsthand and help you fix it accordingly.

Can the oil pan gasket replacement be done at home? 2006 Lincoln Ls V8. Does it use just a liquid gasket or does it use an actual gasket?
ANSWER : Hi there. The oil pan gasket is either a gasket of cork or rubber (silicone molded) or a spread of RTV Silicone. The oil pan gasket can be removed at home, you will just have to jack up the vehicle and set it on jack stands. It is best to have the whole vehicle on jack stands, however, if you only have two jack stands, be sure to set the parking brake and put wheel chocks behind the rear wheels. If you need further assistance with replacing the oil pan gasket, then seek out a professional, such as one from Your Mechanic, to help you.

2006 BMW oil filter gasket keeps breaking and oil leaks from oil filter. Oil leaks only after starting car in morning. PCV valve?
ANSWER : Hi There,
It sounds like you may need to replace the oil cap o-ring. If you haven’t done this before there are two O-rings to replace; a small green one on the base of the filter cap stem and the large black one that seals the filter cap (which seems to be the one you are having issues with). The large O-ring sits in a small square-shaped groove that is at the base of the oil filter cap. It is very easy to not properly seat the large O-ring because the threads for the oil cap are quite large and will accept the O-ring if you are not careful. I would suggest having a professional from YourMechanic come to your location to take a look at your vehicle.

If you have to add oil all the time and there is no oil puddle left on the ground but the dealer suggests an oil pan gasket leak h
ANSWER : Hi there:

On any engine that has issues with loose or damaged internal components, such as valve guides or piston rings, going through oil frequently is commonplace. If the oil pan gasket is leaking, it may be burning on exhaust before it hits the ground. The best way to diagnose this is to check the tail pipe. If there is visible smoke coming from the tail pipe during acceleration, the issue is with the piston rings. If it’s during deceleration, the issue is with valve guides. If it’s smoking all the time, it could be that fixing the oil pan gasket will solve the problem. If you’d like assistance in diagnosing this issue, a YourMechanic certified technician can be dispatched to your location to perform an Oil/Fluid Leak Inspection on your vehicle.

after replacing oil pan gasket,low oil level light stays on, but oil level and pressure are normal?
ANSWER : Bob: Thanks for your inquiry. Oil level and oil pressure are measured using separate sensing systems. If the level sensing feature stopped working at the time the pan gasket was replaced, either the level sensor was damaged, not reconnected, or the wire harness and terminal were damaged. There is a possibility that the wire harness was just never re-connected to the level sensor so check that first. If you desire that this problem be diagnosed by a certified Mechanic, dispatched by YourMechanic right to your location, please request a warning light diagnostic – oil level and the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

2008 335xi oil pan gasket hell…..
ANSWER : Your 335xi BMW has very good splash guards and under covers to keep water from splashing into the engine bay as well as oil from major leaks from hitting the ground. The high price tag is pretty fair for the amount of work required to repair these type of leaks on your vehicle. Oil leaks only get worse. Plus, if the oil leaking from the valve cover gets onto the exhaust manifold in high quantities, this can burn the oil and cause a lot of smoke or even a fire. A leaking oil pan and crank seal are much less dangerous, but if the oil leaks to a low level and you don’t realize this while driving it can cause major damage to the engine and turbocharger. Letting it leak is not the way to go as topping the oil off every so often on top of the oil changes can get very expensive over the course of a year. If you want to keep the vehicle for a long time and in good condition, fix the leaks. Consider getting the car’s oil leak diagnosed and estimated by YourMechanic for a lower cost alternative. Our technicians are just as capable and can do the work at your home.

The oil pan gasket is protruding from the front of the oil pan. It sticks out 1". Has this happened to other B3000’s?
ANSWER : Hi there. Sometimes when certain gaskets are tightened down, they can stretch out and extend past their normal boundaries. As long as the oil pan is not leaking any oil, I would not consider this to be an issue. If the oil pan does begin to leak oil in that location, then I would recommend having the oil leak repaired as soon as possible. This is not only a common issue on this vehicle but could potentially happen on any other vehicle with that same style of gasket. If you begin having drivability problems, then have the car inspected for any corrections that are needed.
