2000 2500 4x4 silverado with 6.0 & 180,000 miles , should i pull the engine or try to change rod bearings while still in the truck ? i hear a slight knock when i start it in the morning -it goes away after it warms up,other than that it runs strong and doesn't smoke ,leak or use oil ...........any help is appreciated
Prolly just piston slap man. Don't think that a rod bearing change is needed. And if so I would remove the engine
could just have a lifter that has to pump up...mine old 5.3 used to do it bad
Yep that's definitely not a rod bearing.
+1 mine does the same thing, has for yearsQuote:

I agree that it is not a rod. However, if you ever have to do rod bearings. It is mush easier with the motor out then in the truck. I tried it and pulled the motor to make it easier.
yep, completely agree with what already been said. Just get used to the cold start piston slap, it's normal.
I just got done doing rod bearinngs and katech bolts, along with a bunch of other things on a rebuild, and no way I'd bother with it in
the truck! Just dropping the pan alone would be a pain!
thanks to all that replied,it seems like i have nothing to worry about
