Guys,
I took my truck over to my buddy's shop. He's pretty convinced that my 2nd cylinder from the front of the truck on the passenger side (#3?) is causing my truck to be violently loud, vs not loud at all.
So I know that the truck does not sound like any other 7.3 (that's running right), it has a distinctive clack. It's not a knock, it's not a tick, it's a clack. Everyone recognizes my truck from its distinctive clack, it's that pronounced. So we tested which cylinder it was on, the noise is 100% coming from cylinder #3. It's not the injector, because when the injector is swapped out, it's not making noise on that new cylinder.
It's definitely in the rotating assembly. He thinks it's a bent connector rod (but I have a 2001. It should have PMRs, meaning it should shatter rather than bend??). The other mechanic thinks it could be a wrist pin. What are some things you think could be causing it. I'm taking it to shop tomorrow, I can get readings tomorrow from a scan-tool. As far as we've tested, no loss of compression, no loss of power, no white smoke, no miss-fires, nothing. Just a STUPID amount of noise - which I've personally come to live with, but now that I'm trying to build power, I don't want a weak link just waiting to snap on me.
If you guys want, I can post a video of my 7.3 clacking away so you can hear the noise, just understand it won't be studio quality sound.
