So I've been hearing some chatter while coasting on the highway, i initially thought I was just in need of a valve adjustment because it sounds so similar to chattery valves I've heard on other engines. Did a valve adjustment and the noise is still present. After some long drives on the highway I realized if I'm coasting and put the slightest bit of pressure on the clutch the noise goes away. And when I say slight I mean slight, you could lean and empty sneaker or work boot on the pedal and the noise dissapears. I also noticed if I'm coasting and press the clutch pedal in and let it out the noise is gone for 5 seconds or so then returns. There's no noise if I coast for a long time with the clutch in either. Any ideas what it could be? It's deffinetly coming from bell housing back of motor area that's why I initially thought the old girl needed a valve adjustment, couple were out of spec but nothing crazy and didn't effect the noise. I'd assume even with that tiny bit of pressure on the pedal it's doing something with the hydraulics to make the noise go away. And as I said it's eirily similar to clattery valves I've heard from different motors in the past. This weekend I'm going to grease that zero fitting that's under the cover by the bell housing, its probably been quite a while since anyone's touch it I've put 30-40k on the truck and havnt touched it myself. It has a valair single disk organic that my buddy installed before I bought the truck so the clutch only has between 30-50k on it since he didn't drive it much. Mostly grandpa style miles too lol
Oh and forgot to mention the noise only happened at higher roms between 2-2500rpm or so. Which made me wonder if its just the right vibration to be making something chatter
