I know everyone is going to immediately say to get a new one cause it's cheap insurance, please don't. I'm looking for actual reasons why, not just a bunch of people jumping on the bandwagon. The car is a 2001 so it doesn't have the older pump that's known to fail. I'm trying to do this thing on somewhat of a budget and it's too expensive to start replacing every imaginable part along the way just because it "could" wear out. The car already has an LS2 chain on it from a previous swap, so having to remove the pump to install a new chain is no longer a valid reason

What is the typical lifespan for a pump? I'm not opposed to replacing it, but would like some facts behind my decision.

my 100k stocker had great oil pressure. I did replace it though. i think as long as you are willing to dive into the motor when you see a problem with oil pressure then dont worry about it. some people only have one car and/or dont do the work themselves so it makes sense to go ahead and replace it.

Very good point. If a shop was doing the work for me then I would definitely have them replace it. It's a PIA to swap so I'd prefer to leave it on and not mess with it right now since it's working.

I have a stock 01 oil pump sitting around if you want it for cheap. Came out of my car with only 10k on it...its basically brand new

I upgraded to a ported LS6 pump when my MS3 went in for safety reasons with spinning it up to 6900rpms.

I would say it really depends on what cam your going with if you should need a better oil pump or what not.

To me honest I believe you should do it since your already diving into it. Obviously it ain't cheap insurance since the part ain't, but with the amount of miles you have it would be a good idea.

I'm putting in a TR224, so nothing too wild. Thanks for the offer, but if I have to take mine off I'm just going to put a Melling back on.

100K is getting close to the end of the usefull life of the oil pump. I would replace it, but it's your engine.

You can either:

A) Not change it and hope it lasts a while, if it goes out you could possibly destroy your engine.

or

B) Change it while you already the front of the engine taken apart! You'll easy access at the pump and you won't have to worry about it for possibly the life of the engine.

This seems like a no brainer, i have 115k on mine and if i was going to cam it or when i do it will get a new pump...

I know the smarter thing is to just replace it, and I'll most likely go that route. My only problem with this logic is that it can be used to justify replacing a lot of parts. Why not just pull the heads since the springs are already off and replace the lifters, since the intake is now off why not throw on a 90/90, well now I'm going to need bigger injectors.....next thing you know it's a 3 grand cam swap.

My 99 LM7 has 189k on the OEM pump idles 40+ at 500 rpms and at 53-54 at 1500k......Both better than the 98 T/A wth a melling 10296. The melling will spike 65psi at 6000k plus though.

My cam swap cost me right around 2Gs. That was with new springs, pushrods, LS2 chain, LS6 intake, cost of tune & yes a ported LS6 oil pump. I had good oil pressure with the stock pump. I was close to 120,000 & its a 2000 but I heard they go bad. A lot here recommended replace it while in there, since I was doing a chain figured why not. Its more work lowering the oil pan but its much easier to replace while you got it tore down that far.

actually if my heads ever come off for any reason im putting new lifters in. if i pull the intake i will prolly put new knock sensors in. some areas of these cars can be problematic so sometimes you replace stuff to save headaches down the road. its kind of the nature of the beast.

Here:s an equation i like to quote
Cheap, Fast, Reliable<<<--------pick any two.

I still don't think it's necessary, but knowing my luck the pump would end up going out a week after the swap. I'm sitting right around $1300 so far, and yes that includes a new pump. I might as well get a pulley while the stocker is coming off.

Yes I'm familiar with that equation, very true. I know replacing parts makes sense in the long run, but just hate spending money on supporting mods. Plus I'm a little salty that I didn't replace the pump the first time it was off the car

1300?

A cam package with PRC springs is 700. 150 for a ported ls6 oil pump, 50 for the gasket set, 20 for a timing chain, 30 for oil, spring tool 120. Am I missing anything, the spring tool is optional as well.

1070, tune...depends where you go, there are 99 dollar mail order tunes

add the insult to the injury when everyone here says "we told ya so..." lol.

I'm facing the same debate, but I have 78k miles on mine and good oil pressure with Mobil 1. I could potentially replace the current good pump and have the new one break cause it was defective or whatever... time to roll the dice?

Was it just the 98's with oil pump problems, or did the 99's have them too?

I already have the spring tool from a previous swap, but I was also including the cost of a dyno tune in that $1300...which runs $500. Speed Inc. is about 2 min from my house, so I was just going to use them, but I'm having a hard time swallowing 500 bucks for a tune on a basic cam only car.

99k miles with cam in sig that's been in for 2000 miles.. 35 at hot idle and 50 plus at wide open.
