If the 2007 Chevy Tahoe has an oil leak then it will come from a few places. The most common reasons are rotted lines, bad seals, or a damaged drain plug in the oil pan. The oil pan itself may be damaged, but this would be obvious if that was the case. You will need to fix these quickly, as a lack of oil can lead to major damage to the engine and transmission, which will turn a small repair into a multi-thousand dollar repair. The simplest ways to notice You have an oil leak is a trouble code telling the oil level is low, or that the oil pressure is low, and the obvious puddle that will be under the car.

In most cases, when an oil leak has been reported in a 2007 chevy tahoe, it's usually the result of a faulty seal in the drain plug. The metal washer needs to be replaced periodically or help prevent leaking.

Common oil leaks on these 5.3 engines are the valve cover gaskets and the oil pan gaskets. Also, if the truck has an oil cooler, those seals leak also. The rear main seal is also common when the engine has a lot of miles.
