Sound of engine has smoothen a bit after the repair of head and cam but it was dropping RPM and blinking CHECK ENGINE light (a few times in 6-7mints). There was also some issues in starting the car means it takes 2-3 ignitions for starting. Initially mechanic wanted to keep car till saturday (Friday is off) and a/c to him "tutor" is having issue, it needs to be cleaned. But I told that I need car so he said to bring car on saturday. Overall it was okay, only problem is I have to leave clutch very slowly when I to drive from zero, otherwise it switches off and secondly pick up is bit slow
