I'm not real familar older Toyotas but I'm trying to solve a interesting problem with a 1989 4Runner. The accelerator got stuck and the motor redlined for a brief moment or two. Ever since then, there's been a "clacking" sound when there is a change in RPM, accelerating from idle or returning to idle. There's no sound when it's just idling and it seems to have normal power.
I'd like to know what is the cause of the noise. My guess would be some part of the valvetrain but I'm more of a pushrod guy so I'm not exactly sure what goes wrong in these motors. Any ideas?
