Long story short, buddy tore apart a 1.6 eco diesel jetta about a year, it sat, then I put it back together with a fresh headgasket/all seals. I got the injectors rebuilt because it wouldn't start. Now it runs and it literally blows oil out from the valve cover gasket and vac pump area and I'm sure other places because its pouring out. What the hell could cause this? I took the oil cap off with it running and it made no difference. There was a puf puff out the hole, nothing too terrible I thought. It dumped a quart of oil out in no time. It never did this before.

Also the engine is blowing out non stop white/grey smoke. I haven't been able to adjust fuel yet as the oil leak is too bad.

Sounds like blowby. I'd do a compression and/or leakdown test. Could be the rings have coked up or otherwise gotten stuck.

I worked on a car that the guy had put the valve cover gasket on backwards and it made a little funnel that poured all the oil down the front of the head.
Do you have the rubber valve cover gasket? Is it installed correctly?

Do you have a new o-ring on the vacuum pump?
These are not normal places for oil to pour out if the seals are good,.. not even with bad blowby.
If the blowby was bad enough to cause this it would probably run away on you,.. it would also probably shove the I-shaft seal out.

in my experience bad blow by likes to shoot oil out of the dipstick tube (anyone else?). my first thought would be a problem in the new head gasket install.... compression leak into oil channel or blocked oil channel. That being said... i would still replace the oil pump and valve cover seals first just to start with the cheapest and easiest suspects
