Hey all new here. I currently have a 04 silverado 2500HD 6.0 4x4. 140k miles.
I recently did a major tuneup all fluids belt coolant etc. I decided to do a seafoam clean. I put half a bottle in my oil and the other half in the fuel tank. My wife drove around that day for about 150 miles. When I got home from work I decided to start on my maintenance. I did my oil change (Amsol 10w-30) got in and a started it, oil pressure at 60psi. When I got out I heard a knock which sounds like it's coming from the bottom in. I took it to 2 different mechanic, one swears it's a lifter, the other swears it's a connecting rod. Currently have 5 quarts of oil and 1 quart of ATF fluid in hopes of a clogged lifter. I pulled each coil plug individually to see if I could find the cylinder knocking but the noise never changed. I've also tried running seafoam in the PCV vacuum line with no reduction in noise. If anybody could try and point me in the right direction or have any tips to help find out where the noises coming from it would be greatly appreciated. I don't feel like ripping apart the wrong side of the motor.
Here she is
Here is the video of the noise.
