rb26 problem

[rb26tommy]

hey guy i have a rb26 240. well anyways my problem is that i am foul out my spark plug #6.and pull the plug out and it has carbon around it but the tip is white. so that tells me i am running lean. well found out that injector #6 has a bad leak in it. will that cause the plug to foul out. also i crank the car up today and let it sitting and was walking around the car and found out that there was some black spec coming out of the exhaust and on to the driveway does that mean the turbos seal/ turbos going bad. last question i have a turbo xs bov on the hot side and looking and the -0.2 and when i am driving around town not getting on it. around 2500/3000 in 5th gear it fell like the bow off is blowing of twice while i am on the gas not letting off. so i change the bov out for another one and it read -0.5 and it still does the same thing. don't really know what its doing. does it matter where the bov goes hot/cold. i have good vaccuam. i have that hook up to my boost gauge and fpr. please help. thanks

wtf is the problem here?

i was seeing if the leak in the injector is making the plug to foul out. and to see what is making the bov do that.

#6 usually runs a little different than the other 5 I am told. Something about the manifolds flow characteristics.
