Default Re: to replace f-23 motor or not to replace dat is da ?

Translation for those who respect english as a language;

So here’s my dilemma:
I have a ’98 Accord EX with an F-23 engine. I just finished paying someone to replace my transmission for $2,000. Not even 200 miles later, the frigging timing belt broke. I had it towed back to him and he replaced the timing belt, water pump, and tensioner. When I went back to pick it up he said “Oh yeah, this is a zero-clearance engine and it bent some valves when the belt snapped. It would be cheaper if you buy a used engine from Woodfin and put it in.” I just want to know if that sounds about right? Should I look at buying a used motor or just try and find a used head? Any advice would be greatly appreciated. Thanks in advance.
To answer your question –

Are you sure you trust a mechanic who didn’t think to bring up the issue of it being an interference motor prior to replacing the timing belt? I’m assuming that since he replaced those components and tried to start it, he discovered it wouldn’t run. This would suggest that either he didn’t set the timing right or the valves are indeed shit; I’m leaning toward the latter. Did he warn you of the possibility of the valves being bent? I would do the following - Take the current head off and inspect the pistons for damage. If there isn’t any then procure a used/remanufactured head. However, if there is significant damage, then a replacement engine would be the other option. A used F23 engine is going to cost a lot more than to just replace the head so unless there were other issues with the engine, it would be in your financial interest to go with the head option. However, if you get a used head, do basic service to it like replacing the valve seals (probably around $100). Also be sure to get new head bolts as they are torque to yield. Good luck.
