hey guys... good news, just recently i had my car top overhauled... i had overheated and i ra\eally needed to replace the gasket and had my head resurfaced... that kind of bad overhaul... just the same i had my valves grinded too... and guess wat... my problem disapeared completely!!!

either on of two things lang yan... my head is really warped or my valve really needs grinding... but my best guess would be that my valves needs the grinding...

well, yung over heat had a purpose...
