probably rod knock. Keep the oil full and keep an ear out for it getting worse. Don't want to destroy your block.

yea, well i got an opinion from some of my toyota friends at the dealership and they all agreed its a rod knock... as evident by depressing the dashpot so that the throttle chokes out... then the sound was clear....

so my next question... im pretty familiar with rebuilding engines.... however i dont want to pull the engine... i was wondering, is it possible to do an in-chassis rebuild? just pull the timing belt, head, lower crossmember, and oil pan. is this possible?

i imagine the rod knock can be cured with new bearings??? is this correct?

Well, there is a lot to do when it comes to dropping the cross member, I haven't done it but I have seen a write up on another forum about it. It would be much easer to pull the engine out unless your hell bent on doing it in car. As long as the crank and the connecting rod journals are ok, then new bearings will be good.

Good luck.
