damage after emissions test?
*selah*
that the service station was not responsible for damage to the car as a
result of the emissions test. I started getting a little worried cause
the engine was reved up so high. The car passed inspection, but afterwards
the steering wheel was vibrating when I was stopped at lights in gear. It
seems like the car was damaged from the emissions test. Does this sound
right? Does anyone know what could be the problem now?
Thanks.

My guess is that you are just more perceptive and therefore noticing
this "problem". I have a hard time imagining that they could have reved
the engine so much that they would have damaged it.

It could be idling rough. This can be caused by alot of different
things.

On the other hand, the rough idline (if this is the problem) could be
caused by, say, a vacum leak from a hose that is not properly connected,
or something similar. Such a "damage" I believe they could potentially
have caused. It should normally be a simple fix though.

Do you mind telling me what state your in? And what company did your
testing? I have a similar problem in Illinois with a company called
Envirotest and even though I have physical proof that they over-revved my
engine (bent valves), and I am having problems getting restitution. I
would say to you, have the car checked by a competent mechanic to check
for possible damage. I would also say that it is possible that they just
cleared out/loosened some carbon when they revved it up if you don't
normally drive the car very hard. Good luck

They probably forced off engine self-tuning during the test and forgot to
set things back to normal. Take it back for a check.
Don't worry about the revving. A car with the hood open sounds like it's
doing 7000 RPM when it's really only doing 3000 RPM. An emissions test
usually involves reving the engine to 4000 to 5000 RPM to heat the oxygen
sensor then taking a measurment at 3000 RPM, or whatever the highway RPM
is.

It's my understanding that this warning is directed primarily at cars with a
'ZF' automatic tranny - (Lots of european cars from the '80s - Jaguar, BMW,
Volvo (1985-87 740; non-turbo - and some others)) - see, aside from being
particularly problematic - the tranny doesn't pump oil while it's in park or
neutral; this is bad. The solution is simple, rev the engine in drive...
Revving a ZF in neutral will destroy it, quickly.

The test I run calls for a 2,500 rpm test. The Honda engine will rev
much higher without a problem. The reason the sign is posted is because
some cars components (not Honda) can get damaged when run at 2,500 rpm
in park or neutral. It would take lots more than an emissions test to
hurt a Honda engine.

I had the inspection done in New York City at a Sunoco station. The car
was definitely not having the problem before the test. Hopefully it's not
something major. How would loosened carbon cause the steering wheel to
vibrate when stopped in gear?

Self-tuning? What the heck is that? Sometimes (on Ford Aerostars for example)
I wish there was such a thing. Perhaps you were trying to say self-testing.
Also, no emission test involves revving the engine to 5000RPMs for any
reason. Can you imagine how many ole' junkers would drive in for testing and
have to be pushed out or towed out (with pieces of the engine in the trunk)
after an I/M240 test?

M & R
be no need too. Cruising RPM in my junk i s2500 RPM at 70 MPH. My Little
truck 2.2L is 3000 at 75MPH. If you were to rev it past 4500 and keep it
there for any length of time I feel it would surely detonate. MY junker on
the otherhand would probably granade at 3500 LOL
The sign is posted because the State or counties mandate the requirements
and how the test is to be done not the shops.

How do you bend valves by over-reving an engine?
Bob May
carbon ends up between the valve and seat and gets crushed into place
there. This will cause the engine to run rough until the carbon is
disloged. If it runs a while without being disloged, the valve or
seat will be damaged. But backing up some, if you do have a carbon
problem then you'll be looking at the problem sooner or later. Fact
of life as the longer it waits, the worse it gets.
I would be more suspicious that a hose or cable got disconnected in
the process of inspecting the engine and that's what's causing the
rough idle. Take it to your mechanic or a friend that's mechanical
and have them look at the car with that fact in mind. If they find a
disconnected hose or cable then have somebody nail the smog guy to the
wall.

I don't read attachments to posts as they may give me a
virus If I expect an attachment from you I will open it..
You may have a brilliant thought but if you put it into an
attachment I won't read it and thus both you and I lose.
I don't like to say it but unfortunatly, there are those who
insist upon being nasty to the rest of us. Bob May

the piston runs into it.

(float) and the clearances that were between the valves and the pistons
at Top Dead Center go away. This lead to valve to piston contact and
voila!, bent valves. Any other questions??

On some engines, rather easily. The valves float, get into collisions
with each other and the pistons . . .
With modern PGM FI rev-limited engines its not too likely though.

I could see a peice of corbon getting stuck under a
valve , as this has happened to me at work when doing a tune-up ( its not
the mechanics fault that you engine is corboned up )
But a vauume hose left off or a plug wire off or miss firing ,or a plug got
fouled is more likly it

scan it before you open it. Some may even scan it for you without the need
to save it to your drive first.
