Driving in to work today, I noticed my oil pressure was a bit higher than normal while on the highway. Typically it runs around the 70-mark at cruising speed but today it was at ~78 or 79 with the guage topping out at 80.

Thoughts?

 

mine goes that high during WOT

 

I sometimes wonder about that as well. Once it gets hotter then it goes down. I just try and hammer on it when its super high. I feel like it might pop a seal somewhere. lol

 

I was only running about 2500 rpms but it was a cold engine so perhaps it was high because of that?

 

Went out to lunch and it's 100* outside so it got up to full temp pretty quick and it was idling at 70psi and any increase in rpm's put it up to 75-78psi.

 

yeah mine is like that too, at WOT it's damn near 80psi....

 

Hot idle mine's around 50psi, cold idle 70psi. Regular highway speed is around 65psi. WOT it gets to about 75ish...

 

Yeah I took it to WOT and it pegged 80 - thinking it's a bad guage/sender - considering hard plumbing a true guage and if it's worth the timem/effort/cost

 

yea my ls1 been doing the same and when i punch it a little it gets like 70 and it just started doing that like a week ago.

 

Now there is a nasty whistle that increases with RPM's
