Half Blocked 1KRFE engine - Toyota Yaris Forums

Hi guy's. The engine on my yaris 2010 is playing funny: strange loud noise at times with huge lack of power. Then everything is working fine. I gave it to my little repair shop. At first, he thought it was the chain and the tension spring so he opened the top and try to turn the engine by the wheel manually. it blocks after one or two turns ( forward and backwards). Chain don't seems loose. He and I don't understand what is happening.
No strange noise otherwise, wouldn't a damage valve produce a hell of a continuous racking ?
I would appreciate some insights.
Thanks Pals
