I am about to rebuild my motor and am wondering if the oil pump needs replaced.
On a cold start up at idle its running 60psi and at 2k RPM cold its at nearly 80psi however on a nice warm day with a hot engine, at idle its at about 25psi and at say 6k RPM its at about 55psi-60psi.
Now here's the kicker, the oil pump has 201k miles on it...Buuut, if it aint broke, dont fix it, right? If I keep it I plan on opening it up and porting it out, Let me know if this is a bad decision or not.

 

replace it..you wont regret it.

 

Definitely replace it with a better flowing oil pump.

 

ported ls6 oil pump

 

Whats the difference if I open mine up and port it?
Read a couple threads and basically the LS1 LS2 LS6 are all the same pump, So if I port my LS1 oil pump, wont it be the same as a ported LS6 oil pump? Is there an issue with my pressure numbers that would need me to replace it?

 

Man just toss the old worn out pump & get a new one. There are some areas in builds you do not want to cut corners on.

 

Alright, Thanks Mike!
