Exclamation FE 460 ?'s Low oil press, clicking sound.

Hot rodders....Help a po' Chevy guy figure out a 460 FE problem please.
Relative stuff, 1975 Lincoln Conti, 460 FE , 12 thousand miles !
Look guys my Dr. wants me to fix his precious Lincoln and heres the deal.
Been sitting for a year not started. He stated he started it and began to tick and run rough.
I go over check the dumb stuff.
In time.
Plenty of oil , in fact maybe a bit over full.
plenty of H2O
firing order correct.
carb is good to go.
Vacuum is fluttering between 15 lbs to 19 lbs.
Put in plugs , # 2 comes out with the electrode smushed down but not knarled.
Pulled passenger valve cover and checked everything was moving, it was.
But very little oil pressure up there?
Anyhoo, it acts like a burnt valve or stuck valve on #2.
Is there some backyard method to unstick valves?
Motor flush ? Do you think the pump is full of sludge or has this baby burnt a valve?
I will go back for a compression test , but untill then wadda think?
This car looks like new, runs pretty good for a 7 cylinder. What happened?

First off a 460 isn't an FE, it's 385 series (now you're really confused). It wasn't really descriptive about the smashed plug. I'd try and blow some air in the cylinder to blow any type of foreign material free. It may not have been anything serious, possibly carbon that broke free after setting. The noise may also be from setting and just need some time to warm up and get oil to the places it hasn't been for a while. If it has all the vital fluids,I'd put in a new plug and run it some. It may come out of it, I'd be slow to pin it on a stuck valve.

The plug damage COULD have been from someone bumping it on installation.
Although it was oil fouled too. There is a fairly good size dent in the oil pan and I wonder about sludge or a bad oil pump?
I have ran the car for 10 minutes a couple of times and the noise gets louder as RPM is increased. The noise is not sporatic (sp) its steady with the rpm , so I ruled out something in the cylinder ? Maybe a dirt dobber nest er sumthin?
The oil light flickers in the car when the noise becomes more pronounced.
Thanks for the help , I thought all Ford Engines were FE's! Oh well learn sumtin' new every day.

From the brief description, it sounds like maybe the oil pump pressure relief may have stuck when the engine was fired up. I've seen this happen after an engine has set for a while and the oil gets varnished. Change the oil and filter and before firing it up get an old dist and knock the pin out that holds the gear and remove the gear. You can use that to prime the engine and check oil pressure without running it any more.

No, the FE is its own series of Ford engine - 332, 352, 360, 390, 427, 428 cu. in. There's been some debate on if FE stands for Ford Engine, or Ford Edsel, but there's no doubt the FE is its own lil animal.
