Well as many of you know, I have the infamous noisy engine. It sounds like a diesel. Yet when I first start the truck, it is nice and quiet. As it warms up, click click click. Well one day I was under the truck when it was running (don't ask me to explain) and I could hear the majority of the noise from the oil pan. Now of course there is lots of metal that the sound, wherever its origin, can reverberate. With that said, I think I have bottom end trouble.

So just for giggles, can I pull of the oil pan to inspect the rods and bearings? If of the bearings turns out to be bad, can I replace all the bearing and rods from underneath the motor? I know a guy who replaced his crank in a 6.2 liter GM.

Any thoughts?

 

you probably have a cracked exhaust manifold, silent when started but as it warms up it sounds like a diesel

 

The kind of engine would be useful. If you say it's a 3.0, you need to search. How well does it run?

 

Sorry, 22r 1982 longbed 112000 miles.

 

yes you can pull the pan and check the bearings and you can replace them from under good luck

 

I appreciate it. I am having a mechanic check it out next week.
