my friends engine is blowing clouds of white smoke. its an OBD0 B18A1 with an OBD2 B18B1 head. only internal work is USDM ITR pistons. anybody know whats causing this? disregard the lumpy idle...big cam...jk its just a vacuum hose which has since been connected

also, can he use an OBD1 IAC valve on an OBD2 head?
