Hi all. I have let our son use our 2003 Toyota Sequoia Limited, and he called and said it was leaking oil badly. I went out to his house tonight and sure enough, there is a lot of oil under the right side of the engine. I then noticed that it looks like something is missing from the engine. It is on the right side of the engine. I have a picture attached. Can anyone look on their 4.7L sequoia and tell me what is missing. The bolt holes have oil in them so I fear the oil is leaking from these holes.
