And you know this becasue? My persoanl experience is that my Sister's
Honda was using significant amounts of oil after 60k miles, my 5.4L V8
never used any oil during the 150,000 miles I owned it. At 150k miles
the fuel economy was unchanged, it ran just like it did when new. I
have no reason to believe it isn't still out there somewhere running
just fine. I belong to a Email group for Ford Expeditions. Numerous
members have over 300,000 miles on their engines. No one has reported
any sort of failure that could be attributed to poor materials.

To be honest, I hear stories like this all the time from Toyota and
Honda owners. My response is, if the engiens are so great, why do you
have the heads off? I've never had to take the head off one of my
Fords. We did have the heads off my SO's Chrysler minivan (burned
valve) and her cyclinder walls were just as perfect as you are
claiming for a Honda (it had around 150k miles). I am also curious how
this plays into your complains about Ford using cast cranks and
sintered rods...neither of these is related to cylinder bore wear.

None of this is necessarily true. Cast cranks have been around for
decades. The process is well know and there are advantages to using
cast cranks over forgings including cost. While forging may have a
theoretical advantage in terms of fatique life, this is irrelevant for
most passenger cars. When was the last time you heard of crank failing
due to fatique in a street vehicle? Ditto for rods. On the other hand
cast cranks are often lighter that forged cranks, can have superior
vibration damping, more complex geometry, etc. Engineers who design
for maximum buzz often overlook the best solution. People who buy
based on buzz words often spend too much. Oh, and Honda has used cast
cranks at times....imagine that.

None of this is necessarily true. You can have lousy forged cranks and
great cast cranks.

Again, when was the last time you actually saw an engine fail due to a
broken crank or rod. I never have, altough my Father once had a car
that threw a rod - 65 years ago.

One of the reason given for Ford using sintered rods is that they are
lighter and stronger than forged rods. I cannot prove this is true. I
doubt you could prove it isn't. There is a lot of advertising copy on
the subject...

I've seen (Honda) cast camshafts broken in half, but that was attributed to
oil starvation.

A girl I used to work with had a '70s Camaro that threw a rod. She admitted
(years later, out of earshot of her father) to heavily overrevving it.

I sold my 96 in 08, mostly because I wanted a Fit. ~ 90K on it, the
only major service was the timing belt, mostly because if the sucker
fails, catasrophic is the corredt word, and the "recommended" is 90K
or 7 years. That's not one of those "oh, I think it can go another
year, it doesn't look bad after 12 years".

Saw the car about 3 weeks ago. Still looks and runs great.

One mod to it that had nothing to do with any of your concerns. I put
some Tokico adjustable struts on it. But I also had some RS1s that
would go on the car twice a month.

disks are more linear. in that respect, they work better. they may not
be as practical for a low usage environment needing non-hydraulic
actuation, but their mechanical function is better. that's why we're
now seeing the [sensible] transition to the disk/drum solution. a
combined disk/drum uses the drum element for the non-hydraulics, and
disk for the normal service use.

they usually break because of fatigue - if wrecked bearings were
witnessed, they're more likely to be the symptoms /of/ the breakage, not
to have /caused/ the breakage.

so you say. my 182k mile honda uses somewhere between 1 - 1.5 quarts
every 10k. what's your point? when i had the head gasket off, there
was no wear lip, you you can't say it's because my engine was worn.

how many hondas fail because of "poor materials"??? i can /show/ you
poor materials in a frod - simply go to a junkyard and look at the
garbage with broken cranks, thrown rods, worn cams, etc.

one came off because a prior owner had the radiator shrouds removed, and
this affects cooling airflow. consequently, i boiled the motor one day
in 110+F heading up one of those long fast grades uphill on the way to
las vegas. after that, the head started to leak, slowly, and 1 year
later, i changed it.

another i replaced because of an oil leak. and another because of a
burnt valve. none are bullshit failures like you see in frods where the
inter-cylinder lands are burned, or the heads have cracked, or the
torque-to-yield head bolts have given way.

so you've never gotten to see how bad that wear lip is!

cast cranks aren't cylinder bore wear, but they are absolutely the
layman's window on materials quality. bores wear when the material is
soft. if the bores are wearing, then you know all the other stuff is
poor quality too.

it is all absolutely true. if you don't want to take my word for it,
read stuff like this.

http://www.jobshop.com/techinfo/pape...inggrain.shtml

http://en.wikipedia.org/wiki/Forging

for the wikipedia, you need to go to high res - then you'll see the
macro grain structure flow lines that forging imparts. casting doesn't
have and cannot create that.

for cranks, the /only/ advantage is cost. it is not material quality -
for the reasons stated.

then you need to go get some experience. go to a junk yard and look at
the disassembled motors. then you'll see broken cranks, and you'll
understand why this is an important issue from a materials perspective.
you should care about the pocketbook perspective too - cast cranks
weigh more and thus cost you more gas.


> On the other hand
> cast cranks are often lighter that forged cranks,

that's complete bullshit. fact: for the same fatigue strength, they
need to be heavier. castings contain their own fatigue initiation
defects - by definition. you have to "over-design" ["over-weight"] to
keep fatigue at bay.


> can have superior
> vibration damping, more complex geometry, etc.

gray irons have "superior" vibration damping, but there are many
different types of cast irons. the ones used for cranks are "s.g." or
"nodular". damping really isn't a feature.


> Engineers who design
> for maximum buzz often overlook the best solution.

"often overlook the best solution"??? you're trying to be humorous,
right?


> People who buy

who is buying based on buzz words? i bought my honda based on
experience. it came with a forged crank because that's the way the
honda engineers designed it and it was sold - it's not like it was a
dealer option!

"at times"? it's a dealer option??? you need to cite your source for
that little nugget.

it's all absolutely true. but i guess your mind is already made up to

so you've driven a few cars and they haven't failed. well, so have i.
but unlike you, i've been involved with failure analysis, and also love
to surf junk yards. you'll see broken cranks on a regular basis if you
seek out this kind of experience, and then you'll understand what i'm
saying better.

lighter, yes. stronger, no - that's a fundamental impossibility.

of course - because it's not!

don't doubt - absolutely i can prove it. you can prove it to yourself
too if you want. go to a junkyard, get samples of each type, then do
fatigue testing.

so? sintering = cheap. honda have been all about cheap in recent years
- that's why they swapped to macpherson strut suspension too. that's
what happens when you have a company run by bean counters. it still
doesn't negate the material property differences.
