Tanner-
Yup. I bet I know exactly what it is. Mine did that too. 2000 4.7 dak
sport 4x4. Anyhow, everymorning, or right after work, for about 3 minutes
til it reached temp, it had a slight knock. well, its was slight at first.
It was under warranty so i asked my dodge dealer. It was a bad rod bearing.
they went to rebuild it, saw the damage had been done, and now I've got a
new short block, w/200 miles on it. If your under warranty i'd have that
looked at right away... but your story sounds just like mine. you don't
wanna run a 20 weight to cover it up. no knocking is good....
Hope i haven't ruined your day. but i will say my local dodge dealer did a
knockdown job on the instal. really clean job. truck runs beautiful, and i
thought i'd be scared of drivin a rebuild/replace job, but i'm tickled to
death it runs so good. I hope yours works out, too..
have a good one
