Valve adjustment specs:
cold Intake .10 to .20 mm. Exhaust .25 to .35mm
hot (60-80 degrees C) add 0.05 mm to the above. thrust plates are available in .025 mm increments. Check the valve clearance every 15,000 miles and hope they are in spec. Both camshafts must come off if you need to adjust.
I wouldn't drive the car until the chain tensioner has been upgraded.
