Reply To: Valve clearance, camshaft, camshaft tensioner β a problem or a serious fault?
The TDC would be specified in the service manual , but you know by now if the timings were bad, the valves will 100% hit the piston and engine won’t even do 1 single full revulotion at this point, you would see dents in the pistons caused by a valve
If you took the valve heads off , did you notice the valves ? Are they fully sitting inside the head ?Β If not could we assume maybe “valve seals” need changing orΒ double check the piston rings
They have notches , but Hyosung wants rings to be staggered ie.

Each row is a ring , but the bottom _ dash is a gap, they must be some distance away from each other ,
If you get 10 kg cm2 compression, that’s GOOD! – now test compression again after running on choke for 5 minutes , so we know the compression values when it was hot vs cold to see if it went up or down.
