99 4.0 Chirping. Unrelated knock when cold. Help!
Chirp
So last night my 99 4.0 started chirping. First rare when i started it, mainly stopped, then on the way home it was a constant chirp at high frequency. This sounds like the 3.0 cam synchro, but I'm not seeing any information for the 4.0. The chirp is present at idle, now intermittent.
Is it the same issue?
Knock
When I start up the idle is a little rough but it doesn't knock. The knock begins when I get on the throttle until the motor gets up to temp. When its warm it doesn't "knock" any more.
I'm a college guy with not too much money, I hope I can fix at least the chirp with my limited tools. Thanks!

If it helps here is a video of what it sounds like. I have been refraining from driving it since I don't want to damage anything else.
