Cynic
A quart every 1000 miles is not normal. Thats definitely something you should get checked out.
A full quart every 1k is a bit excessive, yes. I'd move on. FWIW, my 2001 V10 w/ original 230k does not burn or leak any oil I can measure between changes.
They changed to a newer Power Improved head/intake in 2003, then introduced the 3V in 2005+ years. However, all Econoline's received the 2V version, which arguably is a more reliable setup than the 3V for various reasons. 2003+ motors shouldn't have the plug spitting issue. Also, the old heads prone to spitting can be mitigated by using a torque wrench when installing the spark plugs. There are thread kits as well (Cal-Van is a nice kit) that will fix a spark plug hole for good.
After owning Toyotas my entire life, working on the Ford is a dream. Lots of room and built for maintenance. The MPG of 9-10 ain't much worse than my 80 series land cruisers or even my 3.4L 4Runners.
You can add a 2011+ genuine Ford E-Locker into your 10.5 sterling axle very easily. Just run a switched wire back to it and it operates as any E-locker.
You ask about compression testing - I am uncertain what spark plug access is like on the econoline's but the F-series, you need a spark plug socket with u-joint extension to make it bareable. Pulling all the plugs and checking compression on 10 cylinders obviously takes a while.
Check out Forscan, free software with a lot of great features for Fords. You can run a powerbalance test and see if any cylinders are out of whack before diving in.
Do some research fellas. It's not unusual at all. They don't all use oil but plenty do. I've had 3(?) that didn't burn a drop, my current one has less miles than any of them, doesn't smoke or leak and uses 1 qt. per 1500 miles. Tons of info on this and even a Ford TSB stating that it is normal for the V10 to use a quart from 1000-1500 miles. Why some do and some don't is a mystery no one has an answer to.
I know you are skeptical. I was too. Look it up.
And no, I don't like it at all!!!
