Contaminated OIL ?

[Makdaddy]

Well I have like 7000 miles on my mods.
The oil (Mobile 1 10w 30w) gets black very quickly.
I don’t know what’s contaminating it.
The car also loads up. I drive 140 Highway every day. If I kick it in the ASS
I see black smoke out the back. Wideband most of the time reads 12.3 but on occasion it’s been 11 ish. Now I can run a mile or two and kick it again, and no smoke?
So could the car loading up cause the contaminated oil?
Or are these 2 issues separate. And I have a Tuner, but have not had time to use it

Fixed
The problem was a blockage in the PVC system.
vented the Crankcase and all is well

Do you have an oil pressure gauge?

can send oil to blackstone labs to have it analyzed

If it's loading up maybe it's loading up so much that extra carbon is getting in with the oil.

Diesel engines blow black smoke as we all now and the oil will be black as black can get after 500 miles. All motors have some sort of blow by am I right? So if the blow by contans alot of carbon and what not then it just needs to be tuned. It would have to be pretty bad I imagine to do this on a gas motor tho.

Thanks guys I do have an Oil Pressure gauge it appears normal 70 when cold and 30 at idle warm.
Not sure on the rings, But I guess with the extra boost that’s a possibility.
I will try to get some scans and look at the PVC as well after the holiday.
I’ll let you know what I find

PVC Blockage was the cause
