16.0 staight for intake and exhaust valves
If you have insufficient clearance, the pistons hit the valves, followed by the predictable parts damage. On the other hand, if you have too much clearance, the engine will run, but it won't achieve anything close to its performance potential.
Valve clearance.
The exhaust valve gets hotter than the intake valve.
intake .004mm , exhaus .006mm
An engine valve normally needs to be removed from the head for a valve job, or to replace other parts related to its operation like the spring or valve guide. This is normally done when the engine has a poor seal from the valve/valve seat or oil consumption caused by the vavle guide.
