what has been done to the car?
have you done anything to the car recently?
is the problem intermittent or everytime?
mileage on the engine?
how old is the oil filter?
what grade of oil are you using?
id start off by checking the oil level.
a common problem is the pickup tube o ring being pinched, so if you have changed it recently that may be the cause.
if you havent, it may be a worn out or defective oil pump.
there are multiple oil passages that can leak, but with a little more information from you im sure i can help you pinpoint the problem

So I just bought the car and drove all the way from Santa clarita and drove fine but today till today the pressure was at 10 and I let it cool down turned it on and was at 40 and again once warmed up it went down again oil is full and my buddy told me to buy the oil additives for resealing n see if that works and also there is no leaks

sorry for the hi-jack, but i've been struggling with this very problem.
1st time it happened i was cruising at 60mph in 6th gear, it dropped to 20 and immediately came back to around 45. next time it did it a couple more times intermittently, then while at the track (Willow Springs, not drag racing), I looked down and saw the oil pressure at 20 psi while i was at 6000 rpms. I noticed that pressure read normal until 2500 rpms, above that pressure drops to 20. If pressure was reading normal (about 40psi) and was below 2500, no matter the speed if i braked, the pressure drops to 20
mods are: LTs, cats, 3" TDs, KN FIPK, Vengeance VRX4, new valve springs, PR's, p/p TB, and ford red top injectors and the car is tuned ~53k miles and less than 5k on the cam, new oil/filter (Castrol german blend 0-30).
since that problem it seemed like it was on the pickup/pump side so I changed the oil pump to a Melling and added a oil pan baffle, noticed a little change nothing that fixed or really helped. Then I changed the oil pressure sending unit, big change. Pressure doesn't drop as significant as it did before, but it also doesn't build like it's supposed to when the RPMs increase..NO ENGINE KNOCK/TICK OR ODD NOISES
I'm at a loss. Only thing i know to do next is put a manual oil pressure gauge on and pull the oil pan again to check for a clogged pickup tube
:help:

(this is with the Melling oil pump in)
sorry for the shitty cell phone videos, that banging noise was the phone hitting the dash and steering wheel. It's kinda hard to take video while driving a 6spd :o
Then this is after I changed the oil pressure sending unit:

what has been done to the car?
have you done anything to the car recently?
is the problem intermittent or everytime?
mileage on the engine?
how old is the oil filter?
what grade of oil are you using?
id start off by checking the oil level.
a common problem is the pickup tube o ring being pinched, so if you have changed it recently that may be the cause.
if you havent, it may be a worn out or defective oil pump.
there are multiple oil passages that can leak, but with a little more information from you im sure i can help you pinpoint the problem

SP Motorsport said it was a cam bearing or a bearing problem non the less but i hope its not. i dont know if the owner before me bought a new oil pump when he had the engine built by LAPD. but i maybe getting a Ported LS6 oil pump by TSP and start there. after i do the oil change and oil filter. what should i use 10 30, or thicker or what (camaro noob).

Here is Vid of cold start will update with it warmed up and a quick drive around to show how low it gets when warmed (vid with iphone so not great) also im not sure what to hear for so if u hear any odd noises let me know
here is me driving around my block u could see every time i let off the throttle it goes lower and lower, if i would keep going it will end up to 10psi im guessing
