I had my timing belt go out while my mdx was idling, 207k miles on it! I am unfortunately I'm love with my car still, so I decided to just replace the engine. I have a mechanic friend doing the swap, but I have to order the motor and have no idea where to shop for one? And also need to know the part# ? to be sure I get exact same motor to bolt up proper. Where can I find the #? Any suggestions would be appreciated.. Thank you??
