knocking is not good. could be the bottom end(rods/bearings). this would not be the timing chain tensioner, it is located at the very front of the engine, directly behind the airbox.

 

yeah you are right its might be the rods and bearing luckily my bank gave me extended warrants and i have a 100 dollar deductable and covers all this crap but where should i take it? and the honda dealership? do they have a one time fix it plan for honda owners since they have been having alot of problems with the s2000 early model?

 

???

 

took it to the dealership today but still waiting for results my extended warranty program suppose to pay for everything and i pay the 100 deductable
