hello all, to start things off I have a 2004 GT, merging onto the highway yesterday revving through the gears and all of a sudden I feel a bit of a sputter so I look down and see I have no oil pressure. I then pull immediately over and shut the car off. Started the car back up for maybe 4 seconds to hear any noises. I'm fairly certain I heard some chatter not really hard knocking. Since then I've towed it home, oil levels are good. I pulled the oil pressure sending unit and started the car and but no oil came shooting out..... which leads me here. Seems kind of random that the oil pump would have went no? Although I do have udp's and I've since read that they can mess with the harmonics causing the oil pump to fail over time. I've had the car for 10 years and ripped on it fairly good and absolutely problem free at that. Sorry for the long post but long story short, should I drop the pan and inspect the pan for shavings and the bearings etc. Replace the oil pump and see if she's good to go? Or do you think the damage is done and it's time for a new motor?
Is My Ol Girl Toast?

It sounds like at the very least the timing cover, oil pump and oil pan need to come off to inspect things. If the pump went and it didn't run much after that there is always a chance you saved the engine. The noise you heard when re-starting could have just been the chains slapping around since there was no oil pressure to tension them.
To be honest that's what it kinda sounded like, when I started it this morning I didn't rev it but at idle for maybe 5 or 6 seconds it acted completely normal just no oil pressure. That's when I decided to take the oil pressure sending unit out. I'd hate to do all that work only to find out that internally something is messed up. I guess I could, like you said, drop the pan and cover and check it out, if it's toast then just pull the motor and replace. Car only has 47,000 miles on it and is mint otherwise, plus with all the bolt ons and other 
done to it itd be a shame to just let it sit.
done to it itd be a shame to just let it sit.The mystery is just how long it did run without the oil pressure, I went through 2nd, 3rd and a bit of 4th when I felt it hesitate and then I put it into neutral and coasted to a stop. Maybe I'm dumb saying this but atleast if it seized solid I'd only have one option. Replace. Not diagnose. Potentially fix/replace.
Yeah when I started it this morning it fired up normal as usual as if nothing was even wrong with it. Obviously I won't keep starting it because oil is not pumping through. I guess if I dropped the pan, inspected the bottom half, maybe put a bore scope through each cylinder checked that out, if all was good I'd be half safe to put new oil pump in and let it rip. Easier said than done I guess. A guy quoted me at 8700 for a 4.6 stroked to a 5.1, or 4500 for a crate 4.6. Not sure how much I want to swap a miled out used engine into it.
A good honest engine builder could take your block, clean it out, and put a new forged rotating assembly in for $3500 ish depending on your location. You would just have to give them the block. There should be no real damage done to it. For $8700 you can get a MMR forged stroker long block with TFS heads and custom cams ready to drop in.
I still have a feeling that you can save your engine though without a huge expense.

Ya I called an engine builder today and he told me to take my oil filter off and bring it to him and he can see if there's in my oil then we will go from there, really no sense in getting a crate engine if he could just rebuild mine like you said with some forged . Biggest thing that kills me is being in Canada, all our parts coming from the states and the US dollar kills us right now. I got the winter to figure things out. Hoping for the best. New oil pump and that's it would be ideal!

No oil came out of the sending unit hole when removed? I may have missed it but is there not oil in the engine? Where did it go? Any cracks? How's the coolant look?
Oil just doesn't disappear or vanish. It went somewhere. Unless I read this wrong then proceed with your oil filter inspection.
Do it cheaper and get a low mile crown vic motor (2004-2011 years). Swap your cover and accessories on it and drop it back in. I gave $800 for my 35k mile crown vic motor with a warranty.
They are easy to find.
