They had issues with the intake gaskets in the late '90s, but Ford fixed that issue and since then they have been pretty much trouble-free.

I hate the 4.2L. **** poor NVH, not very economical, and nowhere near as reliable as the 4.6L generally.

Personally, I would pass on it and keep your eye out for a 4.6L truck.

Mine has 202 hp,gets 19 highway,16 city,only has 4800 miles,and is getting better as miles build on it!
True the 4.6 is a good small V8 but it has its drawbacks too!

I can't think of a single drawback to the 4.6L when compared with the 4.2L V6.

The 4.6L has more horsepower and torque (202HP@4,800 & 252LB.-FT.@3,400 versus 231 HP@4,750 & 293LB.-FT.@3,500), is silky smooth, gets the same or better gas mileage and has a better life expectancy.

Go with the 4.6L unless you really don't like changing an extra 2 spark plugs. :roll:

Well then,my company has a fleet of F150s,with the 5.4,4.6,and 4.2.They are having the foreman turn in there V8 trucks in exchange for a 4.2 truck.Why? Better gas mileage,less monthly maintenance,no blown plugs,and is getting the job done the same or better then the V8 trucks!
Like I said,the 4.6 is a good small V8 but I prefer the 4.2.
Oh,and I can see my plugs and change them in just under 25 minutes,without having to disassemble the whole top of the engine!

The 4.2 doesn't get better gas mileage than the 4.6 in comparably equipped trucks. The 4.2 has it's own set of problems, I've seen too many of them with crank related problems to know better.

Like I said,the 4.6 is a good small V8 but I prefer the 4.2.
You prefer a weaker, less reliable V6 with **** poor NVH? The Ford Essex V6 is far and away the worst of Ford's engine families that's seen production in the last 10 years.

Oh,and I can see my plugs and change them in just under 25 minutes,without having to disassemble the whole top of the engine!
I can change the plugs in a 2WD 4.6L F150 in 45 minutes. Like I said, go with the 4.2L if changing the extra 2 plugs is that important otherwise there's no point.

There is absolutely nothing wrong with a 4.2. I am not saying it is better than a 4.6, but I wouldn't say it is any worse either. The torque curve is absolutely flat from just off idle to redline. The top HP and torque numbers do not always tell the whole story. It actually pulls a reasonably sized trailer pretty well. An awful lot of 4.6 trucks came the 3.03:1 rear diff. A 4.2 with 3.55:1 diff will run right with the 4.6 with the higher ratio and get the same gas mileage. My truck has been absolutely rock solid on reliability so far for 130,000 miles. Runs just like it did when it was new. Mileage is not that great of an improvement, but in terms of initial cost, or cost of a used truck they are worth looking at. With all of that being said, the performance and mileage being so equal between the average 4.2 and 4.6 I really don't see the need for the 6 cylinder engine. Since they are out there though, I don't think you can go wrong if the price is right.

The 4.6 and the 5.4 both blow plugs. I've heard the song&dance, but there's still nothing quite as entertaining as having a 7 cylinder paper weight!!!

Nothing a timesert won't fix. Besides, neither one will blow a plug 99% of the time if you just change the plugs before 70,000 miles and torque them properly.
