    Hey all. I’ve gotten myself into a bit of a predicament this weekend and I need some advice. I own a 1995 Tacoma with the 2.7 3rz. I was replacing front main seal and as I was re installing the crank pulley and harmonic balancer I didn’t have the gerotor aligned correctly and I jammed the pulley into the key in the crank and it got forced down and chipped the sprocket for the timing chain. Is this ok to run or is it a big no (I really dont want it to grenade and dick my timing). If it’s not okay it obviously becomes a timing chain job and I was wondering if anyone has any experience with the timing chains in these 3rz as I understand it’s a big job. (Pulling head and oilpan) any advice would be greatly appreciated.

    There is no way I would run the engine like this. That sprocket gotta be changed.
