Question 95 gmc 3/4 4x4 6.5 diesel

i am about to buy a 6.5 but it runs ROUGH at idle, blows white smoke out the exhaust, has fuel in the oil but doesnt have any blow-by out of the dipstick runs a lil better at high idle but still blows white smoke he told me he put new injectors and glow plugs in it could this be a injector pump

How much is twice as much? If its just a little haze I wouldn't worry about it. If it starts looking like my 94 where if you pull the cap off you can't find your way back to put it on then I would worry.
