white smoke is generally coolant.. and the brackets I have but they don't bolt onto the motor, they bolt onto the chassis. El Fin.

Check for oil leaks around the valve cover aka rocker cover gasket. It could be leaking oil into the plug holes or exhaust, then being burned off after a hard run... You may just need a new valve cover gasket. They dry up and crack over time on all engines.

Stock sr intake piping and SMIC correct? Or is it aftermarket / coustom? And in either case your valve cover breather is hooked to a non pressurized line (pre turbo) right?
