What oil and filter you running? Any oil additives?
Also whats you oil PSI hot/cold.
Check your flex plate bolts
How long has it been that way? Did it start abruptly or slowly over time?
It is really hard to tell but it is starting to sound like rod knock to me.
Sounds like piston slap. Too slow to be valve train noise.
It started getting noticeable about 2 weeks ago...and is mostly at idle. I run Rotella 10w-30...and have tried all the snake oil additives...but the oil is CLEAN...like REALLY clean.
How key is 3700 rpms? I ran it at 3000 for 3 minutes the other day to no avail.
