DOES ANYONE KNOW 100% FOR SURE THAT THE FUSION V6 AND THE MAZDA6 V6 ENGINE ARE IDENTICAL??? sorry for cap lock. ive found a mazda engine for around 1500 used and a fusion engine for 700. both have variable valve timing. both are v6. the only difference i see is the valve covers. its going to cost around 1100 for my rebuild after ordering new parts, seals and gaskets. any help will be greatly appreciated by both my car which is currently sitting in the garage with the engine at the machine shop and my bank account.
