How much oil pressure should it be holding at idle?

I like to see hot 30 to 40 psi, but that is not always the case. How many miles are on the engine? Do you still have stock pistons in it? Are you running synthetic? If you have the stock Hyperutectic pistons, then you need to make sure to run synthetic oil probly no heavier then the 10w30 or 15w30 due to the tight clearences on those pistons. Also the synthetic will better handle the higher oil temps the LS1 sees do to no oil cooler.

hmmmm....well first start up the pressure jumped to 40 right off. But lately it will drop to 20-30 after idleing a few minutes. I really don't want to tear into it again incase the pump has something wrong with the seal (melling ported ls6) maybe I'll take a video tomorrow and show you and see what you guys think. Motor is stock and 133k.

Get that thing tuned and you will love it. I installed an El Torro in my friends GTO and after the tune it felt very strong!

If there is an oil pressure issue make certain you did not screw up the oil pump o-ring. Seems like a lot of people screw this up, and eventually it will ruin your engine. The whole design seems stupid to me, but I don't really see how people screw it up.

where is the car idling at? a low idle from being untuned will give a little lower oil pressure too

Dude that pic on the left you have makes my heart stop every time I see it! Wish the pic was larger

If it is trying to die, your oil pressure at idle probly will be low as stated before. Try ond hold the idle at 1000rpm hot and report back to us.

As stated before, the oil pump pickup o-ring is the number one cause for low oil pressure and incressed engine noise after a cam swap. The o-ring gets pinched and causes air to get sucked in, causing the oil pump to cavitated and the oil supplied becomes airorated, then the engine bearings take a dump.

Check the pressure at 1000rpm hot and report back.

car idles at 8-900 with about 25ish lbs of pressure. At light throttle or even 1000rpm car is atleast 35-40. I guess everything is normal.

Yes it's lm1.

Car still makes chatter noise after getting hot. Any input ? Nothings loose.

exactly, you used a new o-ring right...mine did the same thing when i tried reusing the old o-ring (it looked fine and i didnt know any better)...it would be fine on start up then after the oil got thin and hot there was alot of valvetrain noise, way more than normal...i would let it cool and it would do the same thing again...search my name i have a video too in one of my threads for the cam...see if it sounds the same...i can view your video at work right now

edit found the video....let me know still cant view either without streaming here

thats EXACTLY how my car sounds chris. normal at cold idle then just like that after it gets hot. I guess im just a newb and too cautious about it. I dont guess there is anything wrong with it at all which is a relief. thanks for all the input and help guys.

No man that is not fine to have low oil pressure. You must have messed up your oil pump o-ring. Get a new one in there before you ruin your car.

i thought i just read 20psi was fine at the moment, untuned, hot, and 800rpm idle ? we made sure the o-ring wasnt pinched because we knew it was an issue going in. i could be wrong though. just seems like others have seen this and it was no issue.

Did it have 20 psi before you swapped the cam? You can't tune oil pressure in, its a mechanical thing. Did you install a new o-ring? I have read these same issues and what do you know not a month later the guy spins a bearing.
