Hi all me again. I have a couple problems that i cant figure out. 1..When my gy6 engine is ticking over it has a ticking/tapping sound coming from it. Sounds like the valves hitting its cover but no sign of marks and not loose. Plus it gets hot real quick. Could it be a bearing on its way out ? 2.. i sorted this issue..... Thays all. I did find that the valve cover breather had a screw in it cutting off all the breathing (i removed the screw) and now theres no leaking oil anywhere Any help appreciated.
