Hi all,

Hoping for some insight here. I'm at a point where I need to spend a bit of money on my truck in order for it to pass its next inspection (frame patching and new ball joints - unfortunately not DIY items that are in my wheelhouse (pun intended)).

Overall the truck is in decent shape and the engine seems to be running well except for the noise in the video below. It sounds like it's coming from the bottom of the engine, and is only present once the engine is up to temperature. I'm running 15W-40 Rotella that was last changed within the past 500 miles. No flickering oil light or other issues that suggest issues with my oil pump or oil pressure.

Please let me know what you think or if you're familiar with this sound. I'm thinking of trying some Seafoam in the crankcase and intake to clear out any sludge that might be gumming things up.

 

You know. It does kind of sound oil related, but I'd check the exhaust for leaks first. Through my crap speakers, it sounds very similar to an exhaust leak I had on my 05 Range Rover.

 

+1 on the exhaust leaks. I hooked up a leaf blower to my exhaust and sprayed down the whole exhaust with soapy water. I had a bunch of leaks and it was pretty apparent where they were. Took me two times to find them all. I also end up replacing a the tensioner pulley and a couple others because they were causing so much noise. Good luck!

 

+2 on exhaust. Sounds nothing like the front end/ under engine sound I have. I replaced the gasket on my passenger side header and a similar sound to your went away.

 

Thanks. I will check for exhaust leaks and report back.
