lycoming major overhaul

[Marty from Sunny Florida]

Anyone here have cost information to do a major overhaul on a 110 hp engine
(C150). I'm in south Florida and am considering buying a plane with high
time engine.

Thanks
Marty

We just purchased in November an O-235C1 for our PA-12. For a zero time
engine from Lycoming the cost was $16,400 plus about 2000 for
installation and $700 for an STCed Alternator conversion.

Cessna 150's came from the factory with 100 HP Continental O-200's.
Majoring the engine costs 5 to 10 thousand, sometimes more.

There is a huge difference in overhaul costs between the Continental O-200
in the 150 and the Lycoming O-235 in the 152. The cost to overhaul the
Lycoming will be much higher.

[Marty from Sunny Florida]

By how much more is the Lycoming to overhaul and why? I have an old hand A&P
friend who says the Lycoming is easier to work on than the Continental.
Also, didn't Cessna start using the Lycoming in their later model 150's ?

Please reply

No. All 150s came with the Continental O-200. Cessna went to Lycoming engines for the
152.

None of us is as dumb as all of us.

You are so right. I like those little Lycomings with their 2k hour tbo's
and solid lifters. They last forever but are expensive to overhaul.

And reading this months Cessna Pilots Assoc magazine makes you wonder if
Lycoming will be able to stay in business much longer. New list price for
the Lyc TIO-540 is $138K. For the Continental TSIO-520 $51K. Street price
$100K vs $35K. Factory reman list price $86K vs $44K. Factory reman street
price $58K vs $29K. The price of a new Turbo 206 would drop $85K by simply
putting in a Continental. You guys with the regualr IO-540 are getting
ripped off too. New list $72K vs $41K for the Continental IO-470.

All Cessna 150s came equipped with the Continental O-200 (100 hp).
The follow-on model Cessna 152 used the Lycoming O-235. If you're
really looking at a Cessna 150 forget about Lycoming overhaul costs.
It doesn't apply.

Latest price for a set of rings for a lycoming O-235 is $1600.

How does one overhaul an O-200 for "5 to 10 thousand"? Five
thousand would be beyond believable. Ten thousand would
be cheaper than any price I've seen.

If OH'd with the proper parts, the Lyc O235 is good for 2400 hours TBO.

Just had one at the airport roll over dead after 800 hours. It was flown
regularly.

LMAO! Good one!

IMHO, overhauled Continental O-200 cylinders don't last, although that's
probably not what happened here. If you overhaul Continental cylinders
they should have bushings installed in the rocker shaft bosses, they should
have new seats and certainly new guides. And probably new springs. Most
A&P's knowledgeable about them will tell you they will last 500 hours max.
In the meantime, worry about cracks, problems in the rocker box, and on and
on.

For the money Milleniums are the way to go. Unlike Continentals, the
Superior exhaust guides, a big problem with all the small Continentals, are
surrounded by the aluminum castings in the heads for better dissipation of
heat. And you're not stuck with the AD requiring you to retard the
ignition timing from 28 to 24 deg. btdc, and losing horsepower. While
Continental cylinders have no choke, Milleniums do --- .002" taper to
account for heat expansion near the top of the cylinder. Then Millenium
valves and guides are set up to take the punishment which causes Continental
valves and guides to wear unevenly, get hot, foul with carbon, and stick.
Milleniums come from the factory with rockershaft bushings installed, while
new Continental bosses are aluminum which quickly wear and get sloppy.

I could go on and on, although certainly not an authority. If you want to
know more read up at Sacramento Sky Ranch's website, read the literature on
Millenium cylinders, or just do some googling on O-200 cylinders, which by
the way are the same for C-75's, C-85's, and O-300's, except for a few
variations with springs, valves, and guides.

We just installed some new Milleniums at around $850 per unit. They came
in big tall foam-filled boxes with pistons, rings, rockershafts, piston
pins, gaskets, yep, just about everything you need for a top except the
tools, rocker arms, and elbow grease. Noted with great curiosity were the
blue inscriptions on the valves and pistons --- the words "Italy" and
"Brazil" respectively. Do you suppose these parts were bound to those
countries and got sidetracked?
