Well Gents,
What started as an exhaust replacement program has changed. by the time the
exhaust on the left side of the engine was removed(12 bolts), there were 5
broken studs and the ones that didn't break, were useless. I made the
choice to take the cylinders down to Zypher to get the studs replaced and
found the cylinders were junk. The exhaust ports on 2 were eroded and 2
were cracked. I believe the 3 on the other bank(their friends) are probably
in the same condition. To finish off the decision making process, 2 rods
are sloppy. Topping the engine won't fix the rods. A major overhaul is all
that is left.
Almost as a side note. When your annual is done, you should remove, and
reinstall your exhaust nuts with anti seize. This will keep your studs from
rotting away like mine did.
I am parking my 500A for a while. It has successfully wiped out my bank
account and credit line. Maybe in a year or so I can start on it again with
what is left.
In January it will be the 3 anniversary of the day I left HWD with it. I
never made it to 90 hours on it.
The sump, fuel bladder, exhaust, engine overhaul, and now this.
My grandmother used to say "It's a great life if you don't weaken", She
never even flew in an airplane.

My, what an ordeal. Sorry to hear about this bilbo. That's going like cruel
and unusual punishment letting her sit for a year. But what can one do.
Perhaps a couple of Colemills might be worth your while (unless you already
have them in there.)

I have fresh IO-470 overhaul on the right side. I can't throw away that
26K overhaul.

Dang Bow!!!
Sure sorry to hear the latest. That just REALLY sucks! Ah, the joys of
aircraft ownership.
Not to rub salt in the wound, but I'd sure appreciate it if you could
provide a little info for my never-ending accumulation of engine data.
What was the total time and time since major on the engine?
(I'm betting that the cylinders were overhauls and not new judging by
cracks - I'm pretty sure YOU didn't shock cool 'em. Exhaust port
errosion is often the result of improper guide geometry)
Was the engine overhauled to "new limits" or "service limits"?
(wouldn't expect to see loose rods on a 470 unless it was way past TBO
or was at service limits when overhauled)
I'm afraid your engine is another statistic in my "if it ain't done
right, it ain't gonna hold up" collection and I'm really sad to hear it.
You deserved better treatment from you bird Bill!
Chris

I never did break don the cost of the overhaul on my IO-470s at Zypher
Engine.
Basic cost $18,900.00
Crankshaft 2,500.00 (overheated and checked)
Oil Sump 700.00 (improper oil pan installed)
Titan Cylinders 1,700 (a little cheaper than the "Black" ones)
---------------------------
$23,800.00
That price is of course , on the ground and with out any new hoses of baffle
material work done. Add $2,500.00 for most of that.

NEVER, NEVER, NEVER, NEVER, NEVER......................................
Never buy an airplane that has a circuit breaker for the Hobbs meter(mine is
less than 4 inches away). I have never heard of a Hobbs meter fire.
You don't need one unless you are going to "enhance" the time.
I think I'll have another beer.

What was the total time and time since major on the engine?
One was 700 hours and the other 800. At this piont it doesn't matter which
one was which.
================================================================
(I'm betting that the cylinders were overhauls and not new judging by
cracks - I'm pretty sure YOU didn't shock cool 'em. Exhaust port
errosion is often the result of improper guide geometry)
Chris, I could not have done this kind of damage to these engines in the
BRIEF(90 hours) period I have owned the plane.
============================================================================
====
Was the engine overhauled to "new limits" or "service limits"?
(wouldn't expect to see loose rods on a 470 unless it was way past TBO
or was at service limits when overhauled)
I haven't looked yet but It could NOT HAVE BEEN TO NEW)
============================================================================
======
I'm afraid your engine is another statistic in my "if it ain't done
right, it ain't gonna hold up" collection and I'm really sad to hear it.
It will emerge in a year or two with two new engines , new exhaust and 5
year props.
It will not be for sale at that time.
