    Noticed on my garage floor small spots of oil. Took it into my mechanic and he told me the rear seal was leaking small amount of oil and as expensive as it would be to change the gasket to just keep an eye on the oil level and continue driving it as is. Bought this car brand new and have religiously taken care of it. Want to know if his advice is okay or should I get the work done. Do not want to risk any major damage down the road!!

Hello. Let me try to assist you the best I can, with the hope of achieving a FixYa rating from you for my assistance.

Changing the rear valve cover gasket on your vehicle would be not considered a "real" big job, but IS a time-consuming job.
In order to remove the rear cover, you first have to remove the intake plenum. If you do not remove the plenum, you can't get to the valve cover bolts that are under the plenum. After the plenum is off, the valve cover is easy to access. You will also need to replace the intake plenum gasket, if you do the job yourself.

I hope this information has satisfied your question.
Thanks for choosing FixYa for assistance!

There is a link in this thread with step by step pictures on how to do this. I'd go ahead and clean out the EGR and the throttle body while I was at it.

OIL LEAKAGE CAUSES


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.

2004 gmc yukon lite came on low oil pressure just had oil change 5 days ago checked it was low about a qt. Has 157,000 miles what can be the cause


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.

2002 Passat, 30 valve V6 has oil leaking on exhaust manifold. VW dealer says its the cam adjuster seals. It looks to me like its just the valve cover gaskets but I can't get an engine schematic to see the...


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....

05 honda accord losing oil


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

Oil leak on 95 chrysler concorde. 3.5


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 ?
