I have an 03 f250 that I recently purchased. The truck had 169k on it and had a bad oil leak so the first thing I did after the test drive and trailering it home was pull the top end off the engine, weld the egr cooler, installed new oil cooler, ICP, HPOP gasket and IPR kit, cleaned the turbo etc...
As soon I got it running it had a knocking sound that sounds like a bongo drum. I did not notice the sound when I test drove the truck but it may have been there. The farther you get from the truck the more noticeable it is up to 100 or so feet away. The truck and it is running great and has TONS of power.
The truck makes around 26lbs of boost and is very smooth except on startup from injector stiction which clears up in about 30 seconds. I monitor the engine with my SCT livewire and the ICP pressures are great as well as the IPR duty cycle, FICM voltage and all other parameters look good too.
The noise is the loudest when the engine is cold and not very loud when the engine is hot. Thru a stethoscope the engine sounds normal from both heads and the block. With a hose I cannot pinpoint the noise. Over the last 2k miles it has become slightly louder.
I have tuned the truck with the SCT and the sound stays the same.
Here is a video of the sound, if anyone could give me some ideas on what this could be, it would be greatly appreciated!
