Oil leak on a 2001 7.3 liter powerstroke

There is no need to add oil to an ac compressor unless you have had a massive leak. new compressors come with the right amount of oil. The compressor oil circulates with the gas and by the time the gas pressure drops from a leak then the amount of oil leaked out is just a few drops. Excessive oil in the system stops the TX valve from working and causes problems . If still in doubt then talk to an accredited ac specialist

I would guess the intake or the oil pressure sending unit.

If it is in fact the oil pan gasket that is leaking, then you would first need to drain out the oil through the oil drain plug and recycle the oil. Then you can remove the oil pan and replace the old gasket with a new one, refill with the proper amount of oil. Then you can run the car and see if it still leaks.

You've got one line going into the radiator and that line exits on the other side. If the leak is outside of the connection and you have enough room to add a few inches of hose to correct it, then just go to a parts store and buy a hose splicer, and 2 clamps to fix.

If the leak is too close to the radiator, buy yourself a small add on transmission cooler & extend the hoses to run to it to cure the problem.

Either way isn't that expensive. The cooler has basic instructions and is fairly easy to install in-line to correct the leak.

good luck

A little bit of oil is normal, but if oil is dripping all the time, the turbo needs to be repaired.

Either valve stem seals are leaking or the turbo oil seal is leaking.

If it's on your intake manifold your distributor seal/o-ring is bad.

this is an oil pressure problem, either a sensor is not sensing enough oil pressure, or the high pressure pump is not building enough pressure(possibly leaking or head is leaking). this engine requires 450 psi minimum oil pressure at the injectors to actuate the injectors.

head gasket!

There is no radiator cap, the Lanos has what is called a "sealed cooling system", popular on newer model European cars and most Asian models, even some of the latest US made cars. You can squeeze and release the upper radiator hose repeatedly to "pump" some of the air out/water in.

The engine has to be leaking water somewhere. It could be a small leak that only leaks under pressure (when the car is hot) and the water is evaporating as fast as it leaks out. This kind of leak can be very hard to find! I had this problem on my daughter's 2001 Lanos until today, when I found the leak. A heater hose burst today while she was getting gas, luckily the car was stopped! It had been using about a tank full of water every month (about one quart or liter), but could find no leak. I suspected a leaking head gasket or cracked (which could be your problem), and was preparing to take the head off when she was on Christmas break from college. I'm glad that hose burts!

A leaking head gasket or cracked head is hard to detect. Most of the time there will only be a small leak when the engine is hot, and the small amount of water pulled into a cylinder is vaporised as the engine runs. There will be no water in the oil unless there is a large leak. Pull the oil dip stick and look under the oil fill cap. If there is a tan looking substance on either one there is water in the oil and you definitely have a cracked head or leaking head gasket. If it's just the gasket you're lucky -- the gasket will usually only leak if the engine has been run very hot (boiling over and then run a bit), and then the head will either crack or warp. A warped head can be repaired, but must be taken to a machine shop for repair. A machine shop can also check a head for cracks, as the cracks are usually too small to see, and usually only open and leak when the head is hot (normal engine operating temperature).
