My car was losing oil. The European car mechanics I was taking it to couldn't figure out how I was losing the oil. The interior of the car started to smell of burning oil. The mechanics were still unable to tell me what was wrong, but were willing to charge me $2000 to try and fix it. I decided not to go back to that garage ever again, and instead, fix the car myself, even though I have no background in car repair.
After searching the web for "burning oil smell Passat 2003 V6", I saw that the valve cover gasket and cam tensioner seals were the prime candidate for the cause of the problem. It took me 10 minutes of investigation, to see that my engine was leaking oil, from those locations. I plan to buy the valve cover gasket & cam tensioner seal kit from BlauParts.com, and tackle the job myself.
very common problem, i replaced mine and replaced/cleaned the entire pcv system as a blocked pcv system can cause blown gaskets.
when i replaced my valve cover gasket i didnt put ant gasket sealer in the corners etc and its now leaking again less than 15000 miles later, time to do it right by following the write up on www.passatworld.com
I can smell the oil thru the vents till car fully warmed up
seems to loose 1/2 quart every two weeks very little leaks and reaches the ground under the car or when im driving and engine is fully wared up
Develop small leak around cam shaft tensioner. Could smell burning oil after car first started and was warmed up, then smell went away. Used a stop leak additive to oil and it fixed it self after 6 weeks or so.
Same problem about a year ago - cam plugs, valve cover gaskets, rear axle seals,.. Finally I gave the dealership carte blanche and told them to replace everything that is or could leak and do the 110,000 service ($3,400,) and the burning oil smell never stopped. They said they'd forgotten to clean the top of the engine. They cleaned it and it still continued. I went back a few times. Still denial. Finally I went to another repair shop and they found BOTH cam plugs leaking. A day later the leak stopped. I think the dealership forgot to replace them and thought I'd just go away. Ha Ha Ha.
Had a crack in my oil pan and was losing oil; a $500 repair bill! Patched the crack and added oil when needed (I neglected my car). Car was acting poorly and replaced both catalytic converters, ABS, Oxygen Sensors, Oil Pan and Oil Cooler. Started the Passat and it sounded great! Within 2 miles I started to smell burning and saw smoke from passenger side engine. Waited 4 days to see if smell would stop and it continued. Called mechanic, showed him the car and 3 Valve Cover Gaskets (VCG) are leaking. After reading online posts and the neglect placed on my Passat, I plan to replace the PCV System prior to any Valve Cover Gaskets. Anyone have any luck with Auto-RX or other similar type engine products to eliminate the VCG from leaking oil?
Change engine cooling holes but that didn't fix the problem because a week later the oil started leaking again heavily. One night driving down the freeway I think smoke was coming in my vents as I approached the stoplight the car died I was able to get it restarted press on the gass for 5 minutes before it will take off again got it around the corner to the gas station and it completely died and I lost all the oil underneath it.
Timing Chain Tensioner failure. Cause timing chain to skip a tooth and cause damage to Camshaft, valves, and cylinder. 6700 worth of damage. Called Volkswagen, they offered to cover 75% (Faxed them my maintenance records). Also Oil leak at rear gasket, which probably led to the failure
I had the major vehicle service done to my car at 135,000. Late I know but car has been maintained to the t's. It ran about $2800. I now have a major oil leak at the cam tension cover..I believe it's called. Every hose was changed out before and now all are oil soaked and swelling as well as my new serpentine belt is coated in oil. The repair shop is not standing by their work at all. I now have another problem. My temp gauge has not worked in years. Now all of a sudden it works and while driving down the road a few days ago all of my vents had steam flowing thru like an old Batman movie where they are getting gassed. It did it twice that day but then cleared up and stopped. The ac would stop during this problem then come right back on. Today my dash has no mileage readout, no clock, temp gauge flips all the way around to point dead south and my fuel gauge flips around like the temp gauge. Has anybody had this issue? Thought maybe my dash brainvgot damp during my "sauna". Please email me any repair ideas. Thanks guys and gals!!!!!
