[QUOTE="Izso, post: 1063810764, member: 2429"] Yeah, I agree with lewis26. I don't think it's the controller cuz he referred to "8 pieces", that sounds like the lifters themselves. ddv : Have a lookt at this : [url=http://www.youtube.com/watch?v=AcT_ZyY3F0k]How VTEC works - YouTube[/url] The tapping noise is probably caused by too much clearance between the lifter and camshaft lobe. The tappet will push the valve down to open it and that tapping noise is what I suspect is causing the problem. You should have someone just inspect the lifters and valves itself. If there's obvious wear on the tappet or the valve then either one of those need changing. You probably can get half-cut parts for less than RM300? How old is the car? Pay someone to re-adjustable the tappets first me thinks.[COLOR="Silver"] [SIZE=1]---------- Post added at 10:00 AM ---------- 6 hour anti-bump limit - Previous post was at 09:57 AM ----------[/SIZE] [/COLOR]oh btw, if it is worn valve / tappets, it's not the end of the world. I just recommend not vtec-ing often. Just drive slower until he can afford to replace them. [/QUOTE]
