Help with engine noise?
Hey everyone! I haven’t posted in a while. wanted to get some feedback on this noise.
I got this 97’ c5 a few months ago and finally got around to working on it. The original 5.7 had a rod knock so I pulled it and threw in a stock 5.3 that I had laying around in the meantime till I get the LS1 rebuilt (I have 3 ongoing projects and the ls1 will probably be done next year).
You can hear the noise around 0:13 and 0:42 both under load/acceleration. Also note I have yet to change the tune so it’s still running a stock LS1 tune.
any help is greatly appreciated! Thanks!

yeah p0153, but I threw it all together pretty quickly and I believe both the driver and passenger side headers are missing one bolt each because i forgot to remove the broken exhaust bolts in the head 🤦♂️. So that may a contributing factor to the code. But that is the only code it shows.
I’ll bust out the welder to get those bolts out soon lol just wanted to fire it up and make sure it was running good. I was super anxious to get it started
