Default LS1 Oil pressure problem

Did a cam and head upgrade on a 02 camaro. Start up was good but now several days (no driving, just running) and a torque convertor install oil pressure is down to 20. I herd the o ring at the pump/pickup may be the problem. Any ideas.

Yes, if the o-ring that go's around the pickup tube where it mounts to the oil pump is not on properly, you will lose pressure. There is actually somebody selling a u shape clamp that go's around the tube and mounts with 2 bolts instead of the one mounting bolt for this reason.

you wont be able to tell even with the pan dropped. the pickup tube has to come back out.
make sure you get a new o ring. gm usually keeps them in stock.
i put one of those BRP pieces on my pickup tube. works like a champ. may need some grinding if you run a double chain.

if it only started after a verter install it could be a cracked oil pressure sensor. we chased the same issue on my car. the shop that did the cam changed the o ring twice and gave up. i was told the motor was tired and i'd have to live with it. i started troubleshooting on my own and found that the sensor was cracked. changed it out and pressure went back to normal. i'm assuming it was from the motor leaning back during the verter install that took place at the same time as the cam. just a thought

Thanks to all who replied. We are doing the operation this weekend, and hope the patient is alive afterwards.
Thanks again.
