Where's the oil going?
Well I just got my 1969 F-250 (360 Granny Four Speed) today and when i left it was full of oil but when i got back it was barely reading on the dipstick, I havn't cleaned it up yet to check for leaks but there are none that are noticable if there are any at all, the truck also does not smoke so i can't figure out where my oil is going, I guess what I am needing to now is what exactly I need to check, what could possibly be the problem here, any info will be greatly appreciated.

You are checking the oil with the engine cold right? When it warms up the oil level looks like it drops because oil takes up less space when warm ( I think ) and lots of it is "sticking" to the oil passages, etc. Make sure you're checking the oil when the engine is cold.

I recommend cleaning off your motor and then spraying it with a cheap spray deodorant. ( I think I used soft and dry, but any spray deodorant will work as long as it leaves a white residue.) spray around anywhere that might be leaking ( valve covers, Oil pan, Etc.( Take her for a spin around the block, and then take a look. with the white residue from the deodorant, you should have no problem tracing any oil leaks.

Greg, you've got it backwards. Volume is propertional to heat. As any solid or liquid heats up, it expands. The only exceptions are certain compounds with crystalline solid structures that show a decrease in volume as they transition from solid to liquid (the prime example being water), but even those compounds, once in liquid form, expand in volume as their temperature increases. Also, oil flows better as its temperature climbs from ambient to operating, so it would be more likely to "stick" in passages when the engine is cold.

hey! I'm not sure how long you've had the truck but one thing that I would check is the rocker arm rail assembly. As far as I know all the FE engines used the same style of rail. Now what I have seen people do is, at some time or another, get the rail turned upside down (there is an up and down). The holes on the rail should face down so that the rockers are rubbing on them and only letting a certain amount of oil enter the valve cover area. When the holes are on top - the oil basically just squirts out and into the valve cover area. This in turn causes the crankcase ventilation system to suck a really good amount of oil without seeming to smoke all that much (as you said barely on the dipstick after one trip)
