Normal Oil Pressure For a Cammed LS1?
Normal Oil Pressure For a Cammed LS1? I just changed the oil on my 2001 WS6. It's cammed with a Torquer V2, and has full exhaust and bolt ons.
What I'm trying to figure out is what the normal oil pressure for it should be?
Before I changed the oil today, it would sit idling at about 40 after a good warm up. But now it sits at about 45-48.
Could it be that I used a real thick oil? They told me to use thicker oil since it's cammed. I used some Valvoline racing oil, forgot what it's called, but it was 20W/50.
Any info would be appreciated.

20w50 would be why you have an increase in pressure. i'm not sure who told you to run a thicker oil because your cammed but i would do a little research. unless you have a built motor with clearances that dictate a thicker oil i would stick with a quality 30 or 40 weight
If you have a stock rotating assembly I'd run across the room and kick in the nuts who ever told you to run that oil weight. The stock rotating assembly is 10W30 and I would do 5W30 at best anything above your going to hurt something. Unless your running a combination of an HO+HV oil pump (Melling) with the 10W30 your going to run a little higher oil pressure.
i really don't see you breaking anything from a 50 weight oil. it probably isn't good in the long run and definitely isn't good when the car is cold but i wouldn't worry about it blowing anything up. i would switch back to a 30 or 40 weight but i wouldn't hesitate to drive the car either

All engines are different with different mileage so I don't know if there is a standard for oil pressure.
I have a ported LS6 Oil pump and @ idle my pressure is usually 50-55 HOT, during cold start Idle it reaches 60-70 easy and @ WOT it wouldn't surprise me if it's at 80 but honestly i never paid attention while at wot.
According to the manual
@1000 Rpm 6psi minimum
@2000 Rpm 18psi minimum
@4000 Rpm 24psi Minimum

your fine. nothing is going to break lol!. I would switch down to a regular weight oil. I ran 20w 50 in my 383 lt1 car, but it was built for that oil. All you are doing is leaving power on the table by running that thick oil. a cammed ls1 oil psi should be no different than stock, unless the oil pump has been modified.
