Oil leakage Whenever i drive my passat,and leave it parked at one place,the gear oil keeps dropping down,dont know why,but this happens all the time,what can i do about this please.And also whenever my gear is set to DRIVE for automatic,it lifts immediately,like i hold an emergency brake,but its not.

Hello Tnelson, I had this happen to my Ford. There was debris in the crankcase. After driving ten minutes, the oil pump pick up tube screen would clog up and restrict the oil going to the oil pump. I drained the oil and poured a half gallon of liquid carburetor cleaner into the crankcase. I let the carburetor cleaner soak for a few hours. I drained the carburetor cleaner and changed oil filter. I installed the correct amount of oil and the low pressure problem was solved.

check your spark plugs wells for oil in them. also check for manifold air leaks spray some carb cleaner on the manifold and lister for engine change depending on the cleaner it will speed up on shut the engine down. also do this to air lines. any oil or water in them clean out if oil the seal on the cam cover is leaking.

To check whether the coolant is entering into the engine oil or not, do the following.
- Park the car on a level floor.
- Check engine oil level on the dip stick and mark it with nail polish. Let it dry. Confirm the oil level. Put the dip stick back.
- Apply about 10 psi external pressure to the coolant system, while keeping caps in place.
NOTE: It is advised to use the coolant system tester. In case the tester is not available, ask any technician to do it for you. Or you can use a bicycle pump with gauge installed on it to pressure the system up to 10 psi. The system should held the pressure up to 30 Seconds.
- If the pressure is maintained for 30 Seconds every thing is good at this time. Ensure that the air is not leaking through your external pump system with which you are testing the system.
If the pressure drops, there will be a leakage some where. Either external or internal. External leakage can easily be observed while carefully examining the hose pipes, clips and joints on the engine.
Internal leakage can be determined by checking the engine oil level again.
- Take out the dip stick and inspect the oil level. If the engine oil level increases it confirm the internal leakage.
- Internal coolant leakage could be due to:-
1. Cylinder head bolts loose or under torqued. (Re-Torque the bolts).
2. Burnt cylinder head gasket. (Always use original spares).
3. Cylinder and head surfaces warped. (Surface grind the cylinder head on surface grinding machine and replace the gasket).
4. Any corroded lid in the cylinder block or cylinder head assembly.
5. Oil cooler, if any.
If the test report of above mentioned procedure is found to be OK, start the engine, pull up dip stick a little, open breather tube from the tappet cover, keep it open and keep the engine start for as long as the water vapors coming out of these points disappear and the engine oil will become clear to its original color.
At times it happens that immediately after replacing the cylinder head gasket some coolant may flow into the engine unavoidably and keep contaminating the engine oil for quite some time.
Hope that works.

You may have a leaking valve cover gasket and oil is making it's way down to the exhaust or something else that gets very hot. Check your cylinder head for excessive oil dripping down off of the base of the valve cover. Check your power steering pump and hoses for leaks. After you get to where you're driving, look under the car and see where the oil spots are, if there are any. If it's dark or black in color, it's engine oil. If it's more like a red-ish color, it's transmission fluid. See where the oil spot is on the ground and check the engine and see about where it could be leaking.

If this has the v6, it's probably the intake manifold gaskets. This is a super common problem with these. You end getting oil in the cooling system and anti-freeze in the oil, they also leak externally when this happens. I would get it looked at/repaired asap or severe engine damage will result. I've had to replace quite a few over the years.

If no external leak and the transmission fluid colour looks white, the problem belongs to the automatic gearbox oil cooler. The oil cooler has broke mixing the gearbox oil and coolant causing this milkshake. It's a small radiator core type oil / water heat exchanger. It is cracked inside and transmission oil is mixed with engine coolant. Because the transmission oil pressure is greater than engine coolant pressure, the transmission fluid level drops. See also the coolant colour inside recovery coolant reservoir inder bonnet! It could be like this:

In the picture above the transmission oil pan was removed for oil filter replacement.

Need more clarification when driving and park. Happen to vw a lot with no solution. Could be electrical ( Tcm + Wiring conector, ECM) ( fluid change fluid+filter add lucid tray oil) or mechanical. Rattle could be engine or evap thing located under or next to air filter. Alternator also. The engine you speak of is know for sludge build up problems by VW. They've even made recalls base on what I've heard. Check oil circulation and how to fix oil circulation problem. Drop the the oil pan and clean filter screen where it sucks in oil. Other things related need to be unclog..

first i would check the transmission oil, do this by starting the engine and leave it running, select all the gears (park, Reverse, neutral etc) then put it back to neutral, leave engine running then locate the transmission dipstick in the engine bay, remove and wipe the dipstick, replace then pull out again, if the oil is showing between the cold and hot marks then level is ok. I shoing lower or none, top up the oil level with automatic tansmission oil, keep rechecking the oil level as adding oil as to ensure it is not over full. will need to select all gears again before checking oil level again.
If the oil level is correct than quite likley a Transmission failure will require mechanic.

call a tire shop or the dealer for the exact tire size. The oil has to be going somewhere. If it's not leaking it's burning. check the plugs for oil, ck for mixture of anti freeze & oil mixing together, if it runs hot/ overheats it may be a head gasket. Or a crank or cam seal that's leaking only while driving. Have it checked, the system is supposed to be sealed.

I think he's referring to the valve body which is the hydraulic part of the gearbox assembly. Can only replace it.
