Slite oil leak from rear valve cover gasket per dealer $650.00

1 a simple compression test will tell you if the rings and valves are bad. thats where you start.. 2 it could be an oil leak under the vehicle , you will see a black spot. do this first it only takes a look whee you park it on dry clean pavement or place a clean piece of cardboard under it.

Where to begin? There are several things and areas that can leak oil or cause an oil leak. Super easy first, when changing the oil if it becomes overfilled it can seep from the seals, the dipstick, out the fill tube, through the gaskets, etc. This can be a permanent issue even if it only happened once or twice and the only repair is to replace the affected seals. Several other options for a variety of vehicles are as follows. Rear main, timing cover, crank seals, cam seals, valve covers, oil pan gasket or puncture, crank sensor, oil pressure gauge fittings, water pump mount (engine specific), head gasket, etc. Also transmission or transfer oil can push past bad seals or gaskets and bad transfer bearings can promote leakage in some models. The amount of oil leaked and location are key to identifying causes. If you are a "do it yourselfer" I recommend putting the vehicle up on ramps, wiping off excess oil with a cloth, then pressure washing (with degreaser for embedded road grime etc.) After the vehicle completely dries slide underneath with a very bright drop light and inspect thoroughly for drips or seepage. Always use proper safety precautions! If you cannot find the leak, start the engine and let it idle for a few minutes then shut it off, allow it to cool and re-inspect. There are several vacuum, gasket, valves, bent cam, and many other internal issues that can cause leaks as well. Hope you find this helpful, feel free to narrow it down for more focused help on this issue.

Here's a link on your code.You have spent a ton of money and the dealer would of done it cheaper.I take my vehicles to dealers for oil changes,they scan and will tell me for free what is wrong since I went there for a oil and not a repair job.Then I can fix my self and not be charged for there labor.

Try checking the oil pressure sensor

This will help.

There can be alot of causes, such as valve covers leaking, oil pan gasket leaking, oil filter leaking, rear main seal leaking, front timing chain cover seal or gasket leaking even bad rings. Does it smoke out of the back? Your valve seals could be leaking. Best way to find out if you have a leak is to inspect the valve covers manually, or take newspapers and lay them under the entire engine on the ground, and it will leave the tell tale stain of a leak. Hope this helps.

have your dealer inspect it for leaks, with this kind of mileage your valve cover gaskets, oil pan sealer and seals start to develop leaks, also try to use a good quality oil because areation is worst with cheap oils,

I have a 2000 Passat V6. They told me that same thing. To replace the gaskets is easy. You just remove the covers and the air filter box and unscrew the 6 bolts holding the valve cover on it and there you go. You want to clean around the gasket service and add a little bit of sealant to the edges. Replace the old gaskets and put everything back together, be careful not to overtighten the bolts, can flatten out the gasket and cause oil leak again. On the right side of the engine, you have to remove the coolant box to get to it. Same procedure....

First have to determine where are you loosing it from.
Possible engine oil leak areas : Valve cover gasket,oil pan gasket, rear main,oil filter. crank or cam shaft seal, oil pump. Pcv valve.
If its transmission oil leaking here are a few areas of interest: shell of transmission( depending where on the shell could be oil pump, or converter., vents, and axle seals.
If your not capable to jack the vehicle up and look for the leak , then take it to a repair shop.
Keep me posted

first thing first... have you seen an actual oil spot/leak on the ground after the car has sat overnight. have you checked the seal around the oil filter.
If you have done those things and both are no... there is a chance it is burning the oil... what does the exhaust smoke look like ?
