I own a 1964 Bug that is has been completly redone and has a rebuilt 1600cc motor in it. It has an oil leak coming from the flywheel that I'm guessing would be from the seals since it is the most common of an issue. However...I was driving it home from a couple of hours away. After 2 hours of driving I stopped to rest and put a lil oil in it to be sure it would make the rest of the 45 min drive home. I put approx. 1/4 of a quart. I jumped back on the freeway and was going about 70 mph like always. About 5-10 minutes later...POOF!!! There was smoke everywhere behind me and in the cab. I pulled over and shut it off. I'm not talking about a lil smoke. ALOT of smoke. Like I blew the engine! Luckily I have a tow bar for the thing and towed it the rest of the way with my truck. Now...when I got home...I checked the oil and it's a lil over. I started it up and it sounded fine. Oil pressure is the same as if I started it cold. What on earth could I have done?

First off.. thanks for a fairly good description.. much better then most.
Next. the leak by the flywheel is likely the rear seal as you mention. It will eventually get worse and make your clutch slip. The repair is easy but it requires yanking the engine (actually a pretty easy job - takes about 30 minutes to an hour ).
The leak on the oil cooler is possible, unless it has always leaked there it is unlikely. Once they are in, they are usually in.
Someone mentioned the gear box.. That's possible too but you still have to pull the engine to find out.
The white smoke and the poof.. it does sound like you overfilled the engine and it simply blew off the excess thru the breather cap, but you should find engine oil all over the areas that were not hot.
Aside from the need to fix the seal (or locate the leak) here is my suggestion:
First clean the engine off.. a couple of cans of engine cleaner and a nearby coin car wash will take care of that. Get down and dirty (bad pun - sorry) cleaning everywhere you can with the pressure wand. (Remember to put a zip lock over the distributor or to bring a towel to wipe inside of it afterwards or the car will not start)
Then change your oil.. new clean oil is different in color then gearbox oil
Then take it on some short runs around town where you can get towed home easily and see if you are blowing more oil . Look to see what color and consistency of oil is dripping.
If the engine operates normally then I would write off the white smoke to simply too much oil.
This won't fix anything but will give you a clean engine and a good idea of what went wrong and where.
good luck...

If we have an oil leak from behind the flywheel *rear seal* we also like to check the case behind number three cylinder. This is where you will sometimes find a crack in the case. Especially on cases that have been bored for 92 or 94mm cylinders. Clean the area the best you can and the apply heat with a propane torch directly behind number three cylinder. If there is a crack the oil will pop out of the crack when the metal get warm to the touch.
If the Oil pressure relief valve is installed upside down or is sticking you will surely have oil leaks. Remember the short relief valve spring (2.44"to 2.52" long) goes next to the flywheel end and the open end of the oil relief plunger goes down. If the case oil passages were not cleaned completely a new rebuild will pull trash out of the oil galleys and can easily cause the oil relief plunger to stick.

you may have overfilled it, and it blew out the breather pipe, and onto the xhaust system. an inspection of oil dripping off of the exhaust would verify this. also, when a valve cover leaks, it drips right onto the exhaust. the smoke indicated oil burning off of something real hot, like exhaust. my plan would be drain the oil completely, put back in the propre amount, run the engine to verify no leakage, clean off the exhaust as much as possible, and drive the car. it will smoke some, due to residual oil on hot parts, but should soon subside. keep an eye on it, but thats what i think it is,

if you payed someone to rebuild your engine, you got ripped off. first the engine should have been line bored, with proper amount of clearance shims and new rear oil seal installed.also a new oil cooler with new O-ring seals should have been installed. the 1600 cc engine holds 2 1/2 quarts of oil. take it back to whomever you you paid and get your money back.

Just overfilled it. The "POOF" part is when excess oil gets blown out. Lucky you, the engine could have gone. If it runs fine now, all is well.

i suspect the oil cooler o rings are not in there correctly . you need to yank the engine to check that and the rear seal , so look at your oil pump gasket first , but when i was into those cars the oil cooler was one of my biggest sources of grief. good luck

I'd replace the whole pan. The body unbolts from the pan and should include everything, including heater channels. I mean, if you want a thorough restoration. I used to have a '72 Bug and just replacing pieces is not going to solve the rusting problem. It's like cancer: you gotta cut it ALL out!

Have you checked the gearbox oil.
