Engine rattle on fresh start up

[RustyRatRod]

The cam and lifters were new when I installed them in 2007.



That describes it exactly, just a momentary clatter that clears up immediately after starting. It never rattles any other time.



I don't think that I mentioned being "worried", just curious to learn if others have had a similar situation.
I have 3 other hydraulic cam Mopar V8s in cars out back that start up and are as silent as new. Even the 383 in Jigsaw, an engine I rebuilt using a Mopar Performance 280/474 cam. That dude just starts and rumbles.
I'm heading out back to tinker. I'll report my findings....

If that's the case, it probably has light preload on a few and they sound off a tad till they get full pressure. Probably a non issue.

Thanks everyone. I wasn’t worried, just curious. My 2007 truck will rattle upon start up if I’m low on oil. With 414,000 miles, it goes through a bit.

Good to know you got it sorted out.
Merry Christmas!

So, one could say you're an old fart driving an old fart.
