Smoking rear?!
Finally, I got my 1965 F350 going! I stuck a new fuel pump on and changed the distributor points and put new plugs in. I stuck a 2 bbl holley off a friends 73 f150 with a siezed motor and the truck is running pretty good. I drove it to work and up and down the road a few times. I have two more questions for you guys though.
1: there is a tapping noise. Is there an easy way to check if its a valve or which valve it is? Do you just pull of the valve covers and can you see something from that?
2. Though the truck ran and drove pretty good, when I parked it after driving about 3 miles, there was (granted not a lot) steam/smoke comming off the spicer 70 rear in the truck. Obviously this is not normal. Could it just be some really old grease that is being rubbed off or something? I did change the rear differential fluid already. I just dont want it to be something like a bearing inside smoking and its comming out the rear :-(.
Thank you to everybody who helped me turn this hunk o' junk into an absolutly awesome truck. I truly appreciate it.

Take a broom stick, long screw driver, or any other long solid object and hold it against the engine. Place your ear over the other end to find where the loudest spot it. This is a backwoods mechanic stethiscope. You'll be able to narrow down the area the tick is coming from this way.
As for the rear end, where is the smoke coming from? The vent tube, brake backing plate, or ??? Pull the filler plug and make sure the oil is all the way up to the bottom of the hole. You might have to stick your finger in to feel for it. If the smoke stinks really bad that is oil.

thanks for the replies. It seemed that the smoke was comming from where the driveshaft entered into the rear, but there was alot of slush on the ground where I parked it and I didnt want to get completely soaked, so I couldnt get a really good look. I did not smell anything at all, which is wierd. I pulled the rear drum on the right hand side but not the left. Also, the inside tire (It has dualies) on the left is shot/flat/shredded. I dont know if this would make a difference, but I dont see how it could cause smoke. Hopefully I'll have some extra time to check these things soon. Again, thanks for the help.

Rotating yoke/u-joints + stationary input seal = friction and heat + cold weather = smoke/steam Try lubricating the u-joints on the drive shaft to cut down on the possiblities of them overheating and burning the input seal. U-joints will overheat very quickly if there isn't enough grease.
