well, i have an 85 with a 22re in it. i adjusted the valves a while back with the engine cold, so i left them a bit loose. it has always been a bit noisey, so yesterday, i readjusted them, this time with the engine warm to .008-intake and .012- exhaust. put everything back on, fire it up, and it sounds and runs great, until it warms up again. as its warming up, it starts making a clattering sound, almost like a bad tensioner or timing chain or something. i replaced the timing chain, tensioner, guides, etc. may 7k ago if that. it never made thi noise until i adjusted the valves. i pulled it back apart, rechecked everything, and everything is in spec. any ideas? has anyone ever had this problem before?
