Anyone else having several little issues with their 4.2L V6 truck?

Oil leak
That's ironic. I just changed my oil yesterday and noticed a small line of oil on the pan. It appears to be coming from around the spot you are talking about. My truck is a '07 with 83k miles. I'm gonna keep a check on it and start trying to get a seal.

Kinda new but have a 2007 4.2L with the same problem. I have oil coming down off the filter, and its getting a bit ugly under there. I'd be curious how long it takes to remove that housing and change that gasket. I may need to locate a gasket too but I really would rather ddo this myself than have to take it to the stealership. I make weekly trips around 500 miles in it and it runs like a champ - excepting for that ugly oil streak I found Saturday!

4.2L oil filter housing/oil pump leak
Boomer6466 - It only takes a few minutes to remove the oil pump/filter housing. It's very accessible and only 6 bolts with low torque on them. It took me longer to clean off the old gasket (on the housing) than it did to remove and reinstall. Bolt sizes, torque values, and the part number for the gasket are in my earlier post. You'll lose about a quart of oil max, including what's in the filter so have a drain pan under the housing when you do the job. If you change your own oil, you should be able to do this. Remove the oil filter, remove the six bolts, clean out old gasket, install new gasket, replace pump & six bolts, torque to the correct values, replace lost oil. You may want to do it the next time you change your oil and have to pull the filter and drain oil anyway. Do not scratch or score the pump when you're trying to remove the old gasket or you may induce a leak even with the new style gasket. You'll notice that the old gasket encompasses one of the bolt holes and the new one does not. Clean that out too. You don't need it with the new gasket. And do shop around on the internet for that gasket. It's a Ford-only part. It's expensive but it works.

I owned a 2005 with the 4.2; drove it up to over 125K before I traded it in, and it was great. The coil pack is unfortunatly a common fault; they can crack, and allow moisture into them. I noticed on mine during a spark plug and wire change at 100K that my coil pack had a hair line crack, so for good measure, I bought a new one and replaced it.
The HVAC blower is not specific to the 4.2 engine, so that can be discarded as a "4.2" V6 related issue.
Since you mention that the towing is light (within the engines rated GVWR), then that would not be an issue, other than your oil change interval should be adjusted.
With using full synthetic, oil change intervals of 8K are fine, but only if you are doing normal driving. Towing places a larger burdon on your engine, so you should consider changing your oil more often, perhaps every 4 to 5K instead of the 8K range.

I know this string is about 4 years old but I wanted to comment on the leaking oil filter housing (really the oil pump). I have a 2008 F-150 4.2L with 65K miles. After the last oil change I noticed oil dripping down the filter. I pulled the filter and tightened the six bolts on the pump. If anything, that made it worse. Since I had good oil pressure I decided I didn't need a pump, just a seal. That seal (2L3Z-6C639-AA) is $70 retail. The cheapest I found was via ebay from a Lost Wages, NV Ford dealer. With shipping I paid $46. It's a Ford-only seal. The new seal (they rolled the part number from -A to -AA) is nothing like the old seal. Different material and a really different style of seal. The old seal had hardened and broke up when I removed it. Some of it stuck to the seal groove on the pump. I had to scrape that out carefully and finish with light wire brush. I put the pump back on, torqued to spec and the leak is gone. There are six bolts, two 8mm (97inlb) and four 10mm (22ftlb). There is plenty of clearance so this is pretty easy job. You don't have to drain all the oil, just pull the filter. The worst part of the job is paying $46 for a seal that can't cost more than $5 to make. With the design of the original seal on my 2008 4.2L I don't understand why they aren't all leaking. Like I said, the redesigned seal is nothing like the old seal.

Spark Plugs
Well I'm very new here so I don't know my way around yet.
I was reading this thread as I am looking at a used 2005 F-150 with the 4.2 V6 engine in it.
Looking at threads for the V8 engines, there seems to be a problem with spark plug removal in the Triton motors.
So I was wondering if there was any such problem with the 4.2L motor.
I really know nothing about the 4.2 but I think it does have aluminum heads.
Anyway thanks all
