Newer motor oil gets black fast

[Talon64]

Well first is I have a brand new motor with forge piston and wiseco pistons 7bolt. The motor finally has 2k miles on it and probably 8 oil changes if not more. I put maybe 500 miles and the oil gets black. I have got it tuned and every pull I do it makes a big puff of smoke and looks like I am doing a smoke screen. Goes through the whole pull but pulls hard. You can tell its black. I really dont know whats going on. Conventional oil only. No boost leaks car holds boost better than most. Think about doing a compression test to see whats going on.

Hows you turbo holding up, any shaft play?
Possibly Blown seals on the turbine shaft.

A blown turbo seal will make it smoke, but the smoke will be blue. IT also won't effect the color of the oil. From what i am gathering, it is rich under boost, that is why it is smoking. Because it is rich you are getting gas and unburnt hydrocarbons in the oil.

Sounds like your running rich, do you have stock injectors?

No shaft play possible turbo seals torn when motor let go?. Tuned high 10s low 11s. Planning on running the holset soon but trying to figure whats going on before putting that on. Torn seals will cause it to turn the oil black fast? Weird part is it didnt smoke bad on the dyno and when I do a pull it smokes else where.

No I have 880's and tuned on dsmlink
