hi all am new to owning a skyline GTST ive had mine about 4 months and its been sweet as a nut untill recently a few days ago it started making a strange tapping noise, the car its self still runs the same as it always has no lack of power etc no drop in oil pressure, problem is i carnt identify whats making the noise i have taken all the drive belts off so i have ruled out the alt, air con, power steering pump etc. noise is quite metalic and gets faster with revs, doesnt appear to be coming from block (but you know how hard it is to pin point an engine noise) only thing i have done recenly is changed oil to a fully sythetic of 5w 40 as recomended by someone on this site, cars got about 55,000 on it. i know its not a lot of info to go on but any advice would be great cheers all :feedback:
