1976 Overhaul, 1100 Hours..Pass???/

Manufacturer TBO is 2000 hours OR 12 years - its a runout engine, and
the price should reflect it. The cam is the most vulnerable as far as
disuse, yes - all splash lubrication up there. Pull a jug or two and
look, beyond that, if it isn't making metal, burns reasonable amount of
oil, and has decent compressions, I wouldn't sweat it much, either.

Hey Guys,

I'm looking at at 172 that has 1100 hours since overhaul, holding 73/90
++ on all cylinders...the only thing holding me back, last overhaul was
1976...

I've talked to several seasoned pilots / aircraft owners that say as
long as it's holding good compressions, don't sweat it....

Any opinions?

Thanks,

OP'er ...grab a copy of AircraftOwner at you local FBO
(www.aircraftowner.com) or Trade-A-Plane and count up how many 30+ year old
Cessna 172 planes are up for sale ...TODAY.

Write down each one on a yellow legal pad. Year - PRICE - hours - top 5
features - location - comments - whatever.

Now, how long did it take to compile your list? Do the same thing next
month - how many new planes between the two lists?

Keep in mind there are even more 172's for sale than just the ones seen in
those two publications.

Thanks for all the advice guys!!!

I just got a call from the current owner...I should have mentioned that
it is going in tomorrow for a complete pre-buy by an AP that is
unfamiliar with the airplane.

I might ask them to pull one or two of the jugs and have a look at the
cam. Is that typically a part of pre-buy???

The airplane is delivered to the AP, my insurance is lined up,
financing is not a problem, I'll post the link and let you guys see
what you think http://tappix.com/728539

Opinions????

Don't pass yet!
Are you sure that's not supposed to read 73 / 80 compressions on all
cylinders?


ha ha, yeah, I noticed I miskeyed that about .5 seconds after I hit
post, unfortuanltey that was about .75 seconds too late....then I
thought it would look even more stupid to make a correction post!

YOU GOT ME!!!!!!!

Thanks again for the advice! Us younger guys would be lost without some
assistance!

Absolutely not. You pull so much as a single nut off a jug of mine, you've
bought the airplane.

Jim,
You are right. I wouldn't want anyone doing that to mine either. What would you recommend on a plane like this
as far as satisfying ourselves that the cam is o.k.? Is a static rpm check and oil filter inspection good enough
(along with the other things mentioned)? An oil analysis history sure would be nice. How about doing one now?
Would you have enough data without an earlier baseline test to make the call?

Unfortunately there's no oil analysis history...that was my first
question....

Let's say this engine DID need at least a TOH.....how much money we
talking about?

I have a 1975 172M now at 1700 hrs TTSN that has never been open except
for the oil pump AD. Oil stays clean using mostly autofuel, with
steady consumption of 35 hrs/qt, compression is good (never has been
great), and past oil analyses have always been excellent. The engine
is smooth, and I don't plan to overhaul it until there is some sign of
degradation. The hours went on somewhat faster when new than now, and
the oil only gets changed annually now.

I bought it new, know its exact history, cruised it at ~55% power, kept
in a low corrosion environment (MN and WI), and preheated always and
only before cold-starting it. Not for sale though.

36K I would walk now 26k would be worth a look!c

Depends on if it needs jugs or not... Figure around 1.5 - 2.0 AMU's
without jugs and add another .8 - 1.2 AMU's for each jug. Please no
flames as this is an off the cuff estimate only. YMMV
