90k miles, time to change oil pump ??
90k miles, time to change oil pump ?? I have just hit 90k miles on my camaro, im about to do heads and intake, lifters, My oil pressure seems to be fine , havent had any issues, But with the milelage , would it be worth it to go aheads and change it out, looking at just the Ls6 oil pump, nothing fancy
Yep. Especially since the chain should already be changed @ that mileage with any camshaft, the oil pump is already off so replace it. A stock LS6 pump is all you need for a street car.
Also, something else I've ran into lately pulling apart higher mileage LS1 F-bodies. Intake/TB gaskets. I've had 2 cars I pulled apart recently with 100K, and when reinstalling with the stock intake/TB gaskets they had vacuum issues until the gaskets were replaced. You can pick up the gaskets at most auto parts store in a Felpro brand and they're pretty cheap. I recommend doing this on ANY 75K+ engine being pulled apart from now on.

same thing with the oil pump. the pump needs to come off to get the chain off so replace both while your there.

Yes, change it by all means. For a cheap alternative, you can run a Melling M295 stock replacement pump. Its cheaper then the ported HP, HV units out there.

Anybody running a cam or heads/cam motor on a stock chain w/90K+ miles is asking for trouble. Seen too many of them break over the years.
I did a cam and heads at 107k...didn't think twice about not replacing the oil pump. But I also replaced the chain...so up to you. But know that after I got it all back together I ended up dropping the oil pan to replace the gasket that I had torn in the process. >

As noted in the quote, the chain is the most important thing that you should focus on & since the chain needs to be done, you should absolutely do the oil pump. Otherwise, the oil pump is a gear pump & shouldn't be an issue really. Maybe, the oil pump spring (fatigue) could use an upgrade to a higher resistance spring, but, why just do the spring when the pump needs to come off to change the spring anyway. So, change the pump & the chain. Upgrade the chain to an LS2 chain. May want to get new sprockets as well, as they do wear which adds to chain slack & can contribute to slight changes in cam timing.
My post was based on the assumption/insinuation that the timing chain was being change, as it should @ that mileage with those mods/power levels. In which case, the pump comes off.
