SPRAYED 01

iTrader: (22)

Im getting some dark grey smoke from the tail pipe. Im pretty sure this started shortly after i installed my heads and intake. At first i thought it was running rich so i brought it to my tuner and he leaned her up at idle. It smells like oil and im about half quart low after 500 miles. I had to reuse the valve seals from my old heads but they only had 2k on them. If its smoking all the time not just at start up could it be the valve seals. No oil on any plugs either. I spray the car all the time, about 7 bottles in the last 2 months. Car still runs great and put down 430hp n/a, what could it be.
sorry for long thread.

Did you use blue loctite or some other sealer on the rocker bolts on the intake side? The threads probably go through on ported LS6 heads.
