Oil pump may be going in the LS1 Not sure if it is the oil pump, gauge (factory) or sending unit, but when I hit the pedal for WOT my oil pressure drops well below 40 then bounces around then recovers and hit around 60. When at idle, it is very bouncy as well, dropping below 40 at times. I have not done anything to this car since I bought it 5 months ago, save the 2K+ miles I put on it, so I know the oil needs to be changed, but I am sure dirty oil is not the issue here.
I am getting ready to do my A4 to M6 swap and will be pulling the engine out in the process so that: 1) I can clean and repaint the engine bay and 2) just to make the process less stressful. Anyways, I figured that at that point I could change out the oil pump. I do not want to do too much to the engine because my planes are to build up a LQ9, or the like, so to put a lot of money into this LS1 would be foolish,; however, I want to make sure it will not blow up on me till the LQ is built and ready to be dropped in.
From what I have gathered, the LS6 ported oil pump is an upgrade for the LS1, am I correct?
What are your thoughts?
Thanks guys!

I have been looking up info on the pored LS6 pump upgrade for my LS1. Am I to understand that if using the LS6 modified pump, I run the risk of the pump sucking dry the oil pan? I was looking at the Katech pump with the shim; is this not a good option unless i get a high capacity oil pan?

If you are looking at the stock gauge and it is being erratic like you describe, it is probably just the sending unit. Buy a new one. If you are using a true mechanical aftermarket gauge then you may have an issue.
you really need to put on a mech gauge and see where your oil pressure is before doing anything-if it's low,i doubt it's the pump-i have seen very few wear out.Generally the bearings wear out first causing the low oil pressure.
If it's bouncing around my money would be on the sending unit. They have a history of going bad - all the time.
