Help needed. Just did my first cam swap. BTR stage 4. New rockers, valve springs, push rods, lifters, timing chain, cam sprocket, and oil pump. I got an extremely loud squeal and chirping sound after first start up. Ran it for maybe 2 minutes all together and has only gotten worse. It’s definitely in the top end. Anything I may have missed or other rookie mistakes??

What's your oil pressure look like?

Assuming it's not a belt, loud chirping = dry bearing and regardless of what your oil pressure looks like, you are going to have to take it apart. "Only got worse" strongly suggests lubrication is the problem, not a belt. If so, even if you had shut it down immediately, the damage was already done. But you should have shut it down immediately and not let it run longer in the hopes the sound would go away. That never works (or at least, it hasn't in my experience).

If you're lucky, it might just be a dry seal and not a bearing...

Did you prime the pump before starting?

Sorry to hear, afraid it is most likely catastrophic bearing damage.

@JAustin had a chirp noise too, and it was NOT a horrible issue. See if he replies before I can go find it in a search.

His was a ticking. Nevermind. Carry on.

Must have forgotten to flush the parakeets out of the oil passages. They get all jammed up in your cam journals and start chirping like no ones business.
