Should I swap out oil pump?

I changed the stock oil pump at 155k, looked like new inside no wear what so ever. With the new Melling stock replacement 10295 pump oil pressure is about 5 psi less @ 2500 rpm and about he same as stock WOT 5k rpm. For me replacing the pump was nothing more than a complete waste of time and money.

Because we thought the oring was bad. It looked like new but while it was apart I figured put a new pump in. I think the reason the oil pressure is lower now is the oring Melling supplies is a bit too small when compared to the factory blue oring. I talked to a top shop LS shop in Texas that does a lot of LS engines, they told me they toss the Melling black orings in the garbage because they leak. They ALWAYS install the larger oring that comes with the pump. I added leak sealer to the oil and it helped, at least the lifters quieted down. It should come back apart and have the oring replaced but screw it, I had enough of this oring BS on these cars....................When it breaks its new car time AND it won't be a GM car. They engineer stupid **** that spoils the experience. The oring along with the unsealed windshield has claimed many many cars. GM knows all about this BS yet let their customers down. F UM!

Mine only came with 2 1 black and 1 green, Melling is as bad as GM. Screw It I won't be doing this bs in the next muscle car I buy! Going to a Dodge, Dodge is a good car, ran over my 1st wife in a Dodge.

Well I guess I shouldn't have posted up. All of a sudden the OP stays at 35-40 on the gauge when its warmed up. It doesn't rise like it should with rpms. Engine is quiet and its runs good, guess time will tell. Could be as simple as a bad OP sender but I'm not touchin it this time. What ever happens so be it. I have my eyes on a nice AWD Charger.

Wait till you lose a axle cv cover on the front of the Dodge.. 2000 bucks later you might have it back from the garage..
But good luck! Hope you "Dodge" the issues..

Going to LOOK at a 2015 RS tomorrow. I don't think we'll buy it but its a step in the direction. I found a 2000 Camaro with 19k on it, guy is 80 years old original owner low mileage but almost 20 years old not sure what we should do. With 175k easy miles on the TA it still drives like the day we bought it but you know bigger troubles are coming with it. I'm too old to do any work on cars anymore.

Change the pump, But do it right .. drop the oil pan, then you shouldn't have any issues with the o-ring. Since you're gonna drop the k-member, change your motor mounts while your there if you haven't before. It all makes sense - since you are there. I did mine several thousand miles ago and I now have 341,000 miles on it. Drives at 60psi and idles at 30.
