So for a little while my cars been randomly chirping and when it chirps the oil presure slightly drops and fluctuates, but when the chirp stops the oil pressure returns to normal, and it more like bounces between 30-40. Well tn it started to chirp a Little more then its ever done before so I just pulled the valve cover to find #valve spring and retainer cap broken? Now what could that be the cause for the noise and oil pressure or do you think theirs more damage im not seeing internally?

All the broken pieces accounted for?
If not, could be elsewhere, such as in the oiling system, etc.
Does the rpm fluctuate when the oil psi does? [Engine misses, rpm drops, oil psi goes with it.??]
Did the issue stop when you repaired the broken spring?
I think I look at that, as a way to assist in determining need for further inspection.
Cut the oil filter open, take a look. See any junk when draining the oil?
A leak down should be done, to make sure there's not a bent valve.

Once you put an aftermarket cam in valve springs become a maintenance item.

I actually found the problem about 10 mins before I posted this. I found all the pieces but who knows what ended up in the motor im going to replace that spring next week, but just for future reference how do I maintaine springs?

Periodically check pressure and change them when they get weak.

No guarantees though a friend let a set of springs go 2 years on a daily driver they were down like 40lbs(he knew they should be once a year), puts a new set in and one breaks at 30miles, then at 130miles another one takes out the motor, at low speed. Was a $400 set of springs and the same ones he had used last time. Quality brand with extra treatments.

You can't just put in a big cam and drive indefinitely.
