Ok let me give a lil history, the truck is a 91 non IC W250 4x. It's got around 250k on it. I've been running WVO/WMO in it for a few thousand miles. Someone messed with the smoke screw before I owned it(cap is damaged)
When you first start it,it runs great no smoke. Then after around 45 sec of running it'll start rattling in the front cover area and it smokes bad. Once warmed up it smokes a lil while at idle and then it'll smoke more while under boost. The smoke is blue/white cold and grey/black hot.
It sounds like the IP thats rattling. Could there be a cracked fuel line(sucking air)? Mabey the lift pumps bad? Clogged in tank filter? I had the front cover off and all looks good, other than the oil pump drive gears out of spec by a few thou.
If it's a wasted IP or injectors no big deal they are gettin replaced anyway.
