Can anyone HELP? I have a sbc 350 with twin turbos and a mild cam. It has a new Howards roller can with roller lifters and roller clam shell rockers, electric fuel pump. It does not use oil and I have no excessive oil leaks anywhere. No coolant loss either. I rebuilt it less than 100 miles ago with everything new. It is smoking out the exhaust pipes and I have done everything I can think of to stop the smoke. It has a reservoir oil tank with a scavenger pump to pump the turbo drain oil back to the fuel pump opening back to the pan. No pressure here, just steady stream of oil. I have disconnected turbo drain line and dumped into open can; I have removed the forced air turbo referenced connection to the hat; I have put PCV on one valve cover; I have vented the other valve cover to the air under car; I have disconnected both forced air tubes from the carb hat; Had a rocker stud broken and replaced with screw in stud and new roller rocker; engine cranks and runs good with no apparent issues other than the smoke. It is a blackish blue in color. I have reduced the amount of fuel by carb adjustment and fuel pump regulator to the minimum amount to keep the car running thinking that it was over fueling. STUMPED.
