Piston/valve clearance 993 rsr cam to 3.8 pistons
To check piston to valve clearance using 993 rsr cams and 993 rsr 3.8 domed pistons how far should I advance rocker to check clearance? ie: set timing with proper lash and then screw in rocker adj screw 1 add'l turn (1mm) and rotate engine slowely to confirm no interference.
