look at the fucking valve dipshit - all those marks are for exiting gas,
not entering. now, you go ahead and argue what you like to the
contrary, but it'll just be ignorant idiotic bullshit.

does you ass fill with water if it's downstream of a fire hose? how
about if it's upstream? cos that burnt valve is upstream, just in case
your powers of observation hadn't allowed you to determine the facts. [sic]

see above.

of freakin' course!!! but it's low compression causing low power yield,
and thus lower exit temps, not "exhaust dilution"!!!! jeepers - for a
guy that was bleating about knowledge of the 4-stroke cycle, you sure
are amazingly ignorant of it.

absolute bull fucking shit. you clearly know as much about valve

absolutely not. you're just guessing. and guessing wrong.
bullshitting idiot.

any idea where I can purchase the motors the move the rear window vents on
the Odyssey?
Other then the dealer that is.
thanks

My first venture into the Honda line has been received with mixed
reviews. The vehicle in question is a new 2009 Honda Odyssey Touring.
The only option added was the trailering package which was dealer
installed. Some nice feature and some just plain disappointing. One of
my biggest regrets was not opting for all wheel drive. Traction in Ohio
winters is tenuous at best.
More importantly, in Ohio winters, I would like a bit more heat! I have
had it back to the dealers indicating it just takes too long for the
engine to warm up. It never reaches half way on the gauge and is
certainly less than satisfying in warming the the interior of the
vehicle. The dealer mechanic has measured the air temp coming out of
the dash as about 160 F which sounds okay, but has not offered the
engine temperature. Having called "the factory", it would seem that
that check is not necessary. The performance would indicate to me that
the thermostat does not allow the engine temperature to reach the 195
design level.
Any ideas out there about how I might pursue an improvement?

a) the Odyssey is not offered with all wheel drive
b) the Odyssey runs great through Ohio winters. That's a fact.

I've been hearing this for much more than a year. Not just for Hondas but
for Toyotas as well.
At first I thought it had to do with defective thermostats. And indeed,
people who had their thermostats replaced under warranty DID report an
improvement. But the perceived improvement may have been imaginary.
Given the frequency with which I'm seeing this problem, I wonder if there
has been a regulatory change to emissions control laws. NOx are a product
of excessive combustion chamber temperatures. Cool the chamber and you
reduce NOx. Cool it too much without restricting the cooling system and you
may actually affect interior heater performance.
I see absolutely nothing in any of the official documentation I have (which
is now extensive) relating to the problem, so evidently automakers do not
believe there is an issue.

I think you're confusing dash vent temperatures with engine head
temperatures.
Assuming a 174F (78C) OEM thermostat and a fully-warm engine, an infrared
thermometer aimed at the upper rad hose outlet at the head will display
about 205F. Anywhere other than that, the thermometer will read drastically
lower. I'm very surprised the tech was able to get 160F at the vents.
That's hotter than the hot water tap in your house. I'd expect more like 70
or 75.
