In this video I inspect and repair the Buick LeSabre 3.8L broken engine upper intake manifold plenum that was a result of an explosion and likely related to a leaking fuel pressure regulator. The video takes you step by step through testing the fuel pressure regulator and injectors as well as replacement and the final outcome. We have learned that this particular issue is more common than we first suspected. Sorry about the audio issues. I am working to correct my crappy microphone problems someday!
Be sure to watch part one where we discovered the damaged intake and formulated a response here: youtube.com/watch?v=urUIDsF6k3w
