oil pressure problem???
i have a 04 chevy regular cab with a 6.0 in it fully bolt on with a high volume oil pump in the brand of the pump is meling dont know whats really wrong with it it when i cranked up the motor for the first time the oil sensor was bad but i had another one in my garage so i cleaned that one and put it on and i had 60 to 65 psi at idle i let it idle for 30 mins or so and then i changed the oil and it went to 10 to 15 psi dont understand what really happened...
some say i should put a mechanical gauge on it to check what the presure really is some say its the oil filter others say that its the gauge and some say thats its even the sensor itself i just need some sujestions on what yall think thanks

I am running the high volume L92 pump on my rig and never have had an oil pressure problem. I frequently carve through sharp twisty roads with my manual transmission 6L and for 5 minutes at a time the tach will never drop below 4K RPM's and then zips back up to 6K+. I've never had oil pressure problems. I'm willing to bet your problem is a sending unit. Sounds to me like you grabbed a dirty one in the garage, cleaned it, installed it and it still has a hunk of crud in it. Get a NEW one and try again. Otherwise have you ever taken the stock pickup tube off? Maybe a pinched oring? Bad bypass in the oil pump?

What would it take to pump the pan dry? In all seriousness unless you stayed above 6K rpm's for an extended period of time I don't see it happening. I've never done it anyways. These trucks have a hell of stout oiling system in them. Quick return oil pan, along with a windage tray and a oil baffle around the pickup to direct the oil to the base of the tube. You'd have to be pulling some serious lateral G's along with sustained high RPM's for a long time to suck the pan dry.

And even at that, I think there's a good quart left in the oil pan...... I still can't see starving the engine of oil on these trucks unless your level is too low OR you're pulling some serious G's while autocrossing making the oil lay flat against the side of the oil pan. Good luck trying to get a truck to handle that well........
