Hi guys,

I've got oil leaks on my engine. When I take off the belly pan, I see some oil on the middle of the belly pan and on the bottom part of the engine. Is it possible that the leak is coming from the Valve cover gasket or the Cam cover gasket? because I don't smell any burning oil.
Is there any other common known part that can
make oil leaks?

Thanks so much

Both the valve cover gasket and the cam cover seal are common leak points.

yes, but I thought the symptom for those leaks is burning oil smell right?
Can you post any picture of how to remove those seals for 2.7T engine?
thanks

I switched from Mobil 1 (smelled) to amsoil and the odor went away. Not a solution to leaking gaskets but....

tend to leak again as quickly, i.e. 40k miles, or are the post factory gaskets better than the ones originally put on the car?

My leak was from oil temp sensor.

ylc--dealer said the sensor was inside the oil pan.

hmm, if it's inside the oil pan, how can it possibly leaking oil to the outside of the oil pan?

thanks
