Lifter pump up....
I'm new to the BBF so bear with me. I am very knowledgable with the Windsor series, but this is my first Fuel Injected Big Block Ford. 
Bought the truck a week ago. replaced a bunch of stuff based on some code ciphering.
Anyway, tonight driving down a long steep grade, all of the sudden I start hearing what sounds like an exhaust leak. Pull off at my work parking lot, check it out and it's actually coming from the valve cover area. Sounds like a pumped up lifter, from my experience.
clack, clack, clack.
Turned off the motor, let it sit for a minute, started her back up, made the noise for a second, then faded and was gone. Didn't do it the rest of the way home. Oil Pressure Gauge does read goofy. Low sometimes, High sometimes. Gotta put a REAL gauge on it to see what's going on.
Long story short, does the 460 have an issue with lifter pump up? If so what is a possible fix. Motor has 129,000 on it. It has been pretty much sitting around and not driven much over the last few years the guy told me.
Thanks

Don't know what the problem might be, but a good oil change may be worth while if you haven't already done so. When you drain it take a good look at what is in the bottom of the pan after you get rid of most of the oil. You are looking for residue and stuff. Normal dirty oil is just black and doesn't have anything noticable except maybe some tiny dust flakes. If you see stuff bigger than pepper, maybe the engine has crud from sitting around or if you did an oil change the new oil loosened some crud.
If there is crud floating around in your oil it might clog up the lifters. Might be worth some engine oil cleaner. There are plenty out there, or you can just use a can of tranny fluid and this may clean things out. the safer way is to do multiple good quality oil changes which will over time clean the engine out with less risk of loosening some big chunk of crud.
Be sure to change the filter and oil soon if you do clean things out. You don't want any new loosened crud floating around.
Good Luck,
Jim Henderson

I had the same thing in my 97 460 and i lost the motor coming home.
The motor threw the first two rods on the front of the motor. Thought it was a lifter
but it would not due it all the time so check the top end of your motor well and cut your oil filter. Look for little bits of metal. Hope this helps out.

Put a cort of tranny fluid in it with a new oil change and run it doun the highway for a while. They will build up a little RPM combined with a little engine heat and help move the oil around the engine and free up things like lifters. Dont hot rod it, just run it. I would use Rotella 15W40 oil in it to. The extra strenght of the thicker oil will help. I run a 20W50 in mine due to it being ran hard when ran.

Added Marvel Mystery Oil
Problem gone. 
I have run 200 miles with it in. Now I'm going to change the oil tomorrow.
AMSOIL AME 15W40 Diesel Oil, excellent oil for relatively cheap. http://www.amsoil.com/storefront/ame.aspx
Mobil 1 oil filter - http://www.mobiloil.com/USA-English/MotorOil/Other_Products/Mobil_1_Extended_Performance_Oil_Filters.aspx

Gentlemen, what you have here is a problem that is twofold: gunked up lifters from an extended park or lack of service by the P.O., and a high-mileage unit with cam and lifter wear. In addition to that weaker vale spring will also add to the problem, especially at higher revs. All will cause lifter pump-up and the click & clack that you're hearing.
ATF works wonders as does Marvel's Mistery Oil, but only when used at about 20% or 1 quart/oil change. I am also a big believer in HDEOs like Delo 400 15W-40. IMO 50W oils are too heavy unless your somewhere where temps remain above 50*F. Anyway, oils heavier than 40W require excessive warm-ups that waste gas.
Having said that, if the gunk is severe enough, you'll wind up pulling the oil pan no matter what.

The 1:4/1:5 is a good mix and won't hurt anything in the long run, but I'm prone to early and frequent changes when trying to rid an engine of "gunk". Good oil with junk it it, um, er, ain't good. The short answer is change it somewhere between 100 and 1000 miles, just depends on how much gunk is removed, otherwise run it to your normal change interval. Other than that, I'm not a big believer in additives as a good oil shouldn't need any.

Update:
Oil changed. Used Rotella 5W40 Full synthetic, 16.49 gal at Wal-Mart. FL-1A filter. Problem is gone. Oil consumption has gone down to practically zero as well. I attribute this to a quality synthetic which has a much lower NOAK volatility than conventional oils.
Nor am I, usually. I do not know what brand of oil the previous owner had in it. I have read nothing but good results concerning Marvel Mystery Oil. I added the Marvel Mystery oil and a quart of oil, it was a low. Changed the oil and filter to the above mentioned, no more problem.
