hello.. just wanna know, isit a problem if the engine block sound like 'ktik-ktik' (as it was very hot) after a long jurney?? fyi, i drove astina bpt with std i/c and no air scoop or what so ever..
:X-:
yup,it was quite unsafe when the engine is running lean...it can cause piston crack...
try to use such like SAFC,Emanage...and etc act as piggybag...
cheers...
happy solving your problem...
