[AT] tractor hauling truck

Sun Mar 8 14:06:36 PDT 2020

An old-fashioned auto parts store staffed with mechanically oriented countermen I used to patronize had a fleet of Vegas that had steel sleeved aluminum engines for deliveries to commercial accounts. I never have had such a good situation since.

I had a small early Vega (72 or 93) and really liked it. Bought it new, so I got to pick options i wanted. Wore engine out, and was not in a position to try overhauling, and did not have capability for an engine swap at that time.
I think it was a real novel approach on the engine design. Sometimes companies just have to try things and see what happens. I recall some other company’s trying a similar cylinder design some years latter that worked well due to better technology/alloys available then.

This reminds me of an early 1970's Chevy Vega I once picked up as a "spare" car. It had more miles than care when I bought it. It was an aluminum block with the cylinders etched to leave a layer of silicon as a hard wear layer. "It ran..." It was an early attempt to eliminate sleeve liners.  I never liked the thing at all and didn't keep it very long.
Here is a page that gives some history:

Sprayed liners are far from new.  BMW built motorcycle engines with this technology back in the 1980's and riders have been know to put 300,000 and more miles on those bikes.  There was a time BMW car engines used a similar technology and developed a bad reputation.  It was actually due to high sulfur fuel, and for one thing our fuel in the USA now has far lower sulfur than back then, and for another thing the whole industry moved to a different alloy that is not susceptible.

Does anyone care what percentage of the fasteners are metric?  I've been wrenching domestic vehicles that have a mix of SAE and metric ever since we tried the metric system in the USA back in the 80's.  It's hardly an issue worth mention.

And several car companies in recent years have paid large fines for overstating fuel economy.  I'll go out on a limb here and guess that Ford has incentive to be very truthful with those numbers.

Some updates on the 2019 F150 no options pickup I looked at.

Base engine is a 3.3L aluminum block V6 with sprayed in cylinder liners. The Cleveland engine plant has an attached aluminum foundry.

Someone somewhere knows what percentage of the fasteners on the vehicle are metric. 

I suspect the combined highway mileage is a tad optimistic.
