I just picked up a '99 for dirt cheap with what I think is rod knock but it's a bit intermittent. The rod knock I've been around before has been really constant, any change in crankshaft speed caused the noise, so figured I'd ask to help pin it down.
Sometimes I get some noise on start up, sometimes I don't and it seems to only make noise in a specific rev range, about 2500-3500 RPM. Sometimes it will make the noise at higher revs but not always. I made a video of the sound, any thoughts?
def knocking, Im 100% sure. I have had experiences of knocking motors, sounds like valves but its not. I had a 1992 supra did this to me, it wasn't bad but after 5km of driving it started to knock and clatter at the lower end then I just got it towed.
