I have a 2004 f 550 6.0 psd w/ 113,000 miles the other day a loud constant popping noise came from the left side of the motor as i was waiting for my son.
I drove home slow and the noise would increase as the rpms would increase.
This noise is so loud that people were turning and looking at me as i went by.
I hear it all times including at idle. Any help on what is causing this would be greatly appriciated.

 

Off the top of my head, it sounds like an exhaust leak. Any other symptoms, loss of power, coolant leak, high water temp, etc?

 

my 5.4 did that when a spark plug blew out of the head (compressing gasses coming out of the spark plug hole). I don't know a lot about diesels, but maybe a glow plug out of place could cause the same thing? I don't know if they just thread out like spark plugs.

 

exhaust leak is what i was thinking, thanks. i have loss of power but water temp is good and no coolant leak. I will look at my glow plugs, i did have a problem with them staying on last year .Thanks for the ideas there good places to start.

 

please be sure to report back what you find......but if it sounds like a his/ticking noise its prob a exhaust leak maybe from a cracked manifold.

 

thanks for the ideas, I think Ill tow it to the dealer tommorow and see what they say, ill update this thread with the info when i get it.

 

Any update?

 

check to see if cac hose,boot or clamp came loose.mine came loose at connection under air filter.hope this helps
