My 5.4 F150 has a leak on the passenger side when I purchased the pickup at 45K. I was wondering if anyone else had the problem and I am glad this forum is on line to answer my questions.

Thanks for the information!

I'm pretty sure mine is leaking on the passenger side as well. The sound it makes starts to go away as the engine heats up so thankfully this thread was able to hep clear that up. Hopefully that will all go away when I can afford to put the new headers on.
