What can cause my 2008 Chevy Silverado to leak oil

Hello, my name is \*\*\*\*\* \*\*\*\*\* thank you for using just answer. The site will prompt a phone call, but that is not always necessary. If it is necessary later in the conversation, I will propose it. I am sorry you are having this concern, but I will do my best to assist you. Failed gaskets and seals in higher mileage vehicles is pretty normal. If you want to pinpoint a leak, the best way is to add dye to the [engine](/topics-engine-chevy/), and then use a blacklight with yellow glasses to pinpoint. If there is a lot of oil and dirt accumulation, it should be cleaned off first, and then re-checked. Hope this helps, thank you. Kyle S.

Will that cause it to have a puddle

Many different things. Also, the engine oil is not the only thing that can cause that. You also have power steering, transmission, and gear oils.
