Well i found the main issue... cyl3 got a part of the head material down to the cylinder and scratched the cyl sleeve and the head has cracked between the valves.... took me 5 weeks before buying a small camera to look inside the suspected cylinders... well...time for a complete overhaul now since these ISM are rare here in Montréal
