I've been working on and with these engines since Ford came out with them. The answer to your question depends largely upon the type of use of the vehicle and if it's been maintained properly. I currently work on Crown Victoria Police Interceptors with the 4.6L and RARELY ever see an engine failure. It seems that they either seize before they get off of the transport truck (brand new) or run 200,000 miles with regular service. The 4.6L engines I work with are serviced religiously and run well over 150,000 mile in SEVERE service. The car wears out long before the engines do.

My 2008 F150 has 344,000 miles on it with the 4.6 V8 engine. It is service regularly and driven daily. The transmission is also original. It has been serviced every year with just a pan drop service, transmission filter, and partial fluid replacement. Have flushed cooling system every 4-5 years since new.

My 2007 Mountaineer has 148000 and has been trouble free. I bought it with 82k on it and immediately switched the oil to full synthetic and have changed it at 5k intervals. The transmission has been flushed twice, as we tow a 5k trailer with it, and had the pan dropped once with a filter change. I also changed the plugs at 84k with no breakage, and will change them again this year. The coil packs are avout 50 bucks a set online and are easy to change. Just keep really good oil in it, and it will take care of you. We still get 22 mpg on the highway with this truck, and it is the awd model. Good luck!
