is it normal to hear the chain rattle on a cold start on an ap2? I bought my car 17k on it and its been like that since then. I replaced the chain tensioner at 40k and that wasnt the problem, a few ap2's that i heard sound just like mine, but all the ap1's are way quiet compared to ap2's on a cold start. I just did a valve adjustment and the valve train is more quiet when warming up. Ap2 guys chime in i wanna know what u have to say.
