I'm hoping someone can help me figure out what this noise is?
I tried cracking all the injector lines one @ a time & though the noise changed a bit it never went away or siginificantly reduced in volume. Most all of them did however create a miss so they are all firing decently well at least.
It's worse when cold & seems to get a little better when warm (vid was taken when warm) and is very consistant. Engine idles pretty smooth, starts pretty easily, revs up well, doesn't seem to miss (haven't went for a ride anywhere yet though) and doesn't seem to smoke anything but black. I was told it does have a fuel chip & PMD mod as well as a replacement injector pump done previous to this issue. The smoke coming from the hood is out of the CDR hole in the valve pan since the CDR isn't currently installed.
I got this truck in pc's & just got it back together - the fella I bought it from said he was pulling the Great Divide on the way to the east coast with a U-haul trailer behind the truck when it overheated on him. He then pulled over & shut it down without letting it cool off first. After restarting it had this noise (he did not confirm it's the same noise since he's no longer around, but I gotta assume it is). He drove the truck the rest of the way here with the trailer AND drove it around here for 3 months with the noise before taking it to a garage. The garage tore off the intake & valve covers & when they didn't find anything there told him he needed a new engine (Less than impressive diagnosis) & that's when I bought it.
