What the f... Time for school Melvin.

disappointed... I'm very disappointed :) well, Time for school for you too, and some practice homework as well, today's homework is: Try to drive 100 km/h on the freeway on 5th gear, then shift back to 1st gear straight away without braking. Please report back to us.
"hint", you can do it, there is no physical locking device like the reverse gear. But what would happen? Please tell us :)
Tips: Please bring a mobile phone with you or carry a bicycle.
Onion, is this just another one of your stupid posts, or are you for real. Firstly, you won't be able to shift back to first gear at 100 km/h. Secondly, why don't you try to free rev your engine past the rev limiter. Go on. That is precisely what it's for, to stop ning nongs like yourself from damaging the engine from over revving. Once again the rev limiter cuts the ignition once the preset rpm has been achieved. It will feel like a hessitation.
you are an idiot
lets just say, if you're in 5th gear and its redline and road speed is 200
just example
same road speed, but 4th gear, what rpm would you be doing, redline still? over redline? or under redline???
use your brain,
over-reving your engine has nothing to do with free reving
you can't over rev your engine when free reving, because of the limiter as you say, but when the car is moving????????
Bludger,,,, another ning nong. You are confusing the Red Line, with the Rev Limiter. You do realize that school didn't finish with primary school, yes.
Enough already with this nonsense. Go by yourself a second hand engine approx $1500.00 from Hontoys in Sydney 0297294400 with low ks as they have 15 engines to choose from and fit it and be done.
Sorry, my bad, please don't try it on the freeway, you could kill more people.
So find an empty long road and try this in order: and please DO NOT reply untill you've tried it.
Steps:
1) Bring a mobile with you and make sure someone knows where you are going
2) Find an empty road
3) Make sure you are the only person in the car
4) buckle your seat belt and setup & secure a video recorder in the car
5) Drive up to 100km/h in 5th gear(in a 100 zone)
6) Press your clutch all the way down
7) Shift your gear to 1st position while still holding your clutch and driving at 100km/h
8) Make sure there is no car behind you
9) Quickly remove your foot from the clutch
10) If you are still alive, please put the video onto youtube and paste the link here, this would be your final project and we may reward you for your great effort for such a bravery scientific experiment
Onion,,, WTF are you on about. Put the Bong down for awhile and try and to make some sense.
calm down guys. Keep the personal attacks and irrelevant posting to pm please.
BTW mishifting is possible , but hardly from 5th to 1st. And it can destroy an engine , pulling the engine to match road speed and RPM to something byound the preset redline. Bang. Is this the case for failed engine ? the thread starter wont say.
Dude, I honestly would not take that sh*t from Honda!
It's one thing to not be able to claim warrenty due to modifiying your car (I actually agree with Honda on that one, sorry). But if they took apart the engine, and took parts from it with out your authority that's seriously uncalled for! Have you paid for the diagonostics etc? You can look at this as yeah it's life, etc etc... but mate this is an asset, which they have damaged in their holding yard, and taken parts of your engine, with no report handed to you what so ever!!!
I would honestly take this to court, and inform the media ASAP.

Mis-shifting is ofcourse possible, as you say not at 100km/h from 5th to 1st. But I don't agree that you can go beyond the rev limiter without fiddling with the computer.
yup technically you cant adjust the rev limiter in anyway , without adjusting via another computer or piggyback.
you can and will "pull" the car beyound the rev limiter by "mishifting" :) IE its a zone where the engine is not designed to go.Invariably = bang.
I don't understand what you are saying Bludger. I don't agree at all. Bennjamin, where did you get this info. Again it is impossible to over rev the engine under any circumstance because the fuel or ignition is cut off. Car manufacturers build these safe guards into their vehicles.
Mis-shifting is ofcourse possible, as you say not at 100km/h from 5th to 1st. But I don't agree that you can go beyond the rev limiter without fiddling with the computer.[/QUOTE]
Mate, what he meant was it is unlikely for people to accidently mis-shift from 5 to 1, they are so far apart, but physically it can be done. Only stupid people with IQ lower than 50 would do it, because it will blow up your engine.
Let me put it into simple english.
You are half correct, the compupter only stops you from reving beyond say 6000rpm, so if you are on 3rd gear, it is not possible to rev beyond that without shifting. However, if you are driving at 3000rpm on 5th gear at 120km/h, and physically shift the gear onto 1st, while the car still rolling at 120km/h, what do you think it would happen?
ok, let me answer it, your car will try to roll at 120km/h for a very short period, maybe 1/10th a sec, then you will slow down very fast, the gear resistance is too high, the wheels are generating too much torque back to the engine, in result, the weakest link in your drive tran will fail and you WILL HEAR BANG!
Second theory, drive your car all the way to the top of the hill, and turn off your engine, put your car into 5th gar and try to roll down. According to your engine ignition off theory, the car shouldn't roll right? Because no petrol is burnt. Please think again. Now when you are rolling faster enough, try to shift it back to 1st gear, still with engine off.
Onion. As soon as the revs go lower than the set point ignition and or fuel starts up instantaneously. Secondly you will physically not be able to move the gear lever into first gear at 100km/h.
Have you driven a manual car? Or should I say are you driving a manual car?
I am driving a manual car, I'm telling you, you are physically possible to shift 5th into 1st, but my IQ is higher than 50, so I would not do it.
I think we are unable to convince you in theory, I know it is unethical to tell you to do this this but as I said before, please don't talk about not possible to shift until you have tried even we warned you that you could damange your car.
Carby equipped cars you could over rev an engine during a mis shift. Thats why companies like MSD ignition and the like make changeable crev limit chips for their after market ignition systems. Computer controlled engines have the rev limiter/over rev built in.
I have four manual vehicles, have driven manuals for 28 years, have been a mechanic for nearly as long. In theory you can say what you like , in practise you would blow your gearbox up in a thousand pieces, if you were physically able to. If you can drive your car at 100km/h, you should theoretically be able to shift back to 1st at 100 ks. But a Honda civic, Nope. Try it, any body.
mmm.. I'm speechless... nvm.. very supprised you are a mechanic and driven a manual for 28 years.
I'm very confused about your answers.. you sounds like 13 yr old for me.
Ok, forget it, lets go back to the topic.
[QUOTE] you sound like a 13yr old to me. [QUOTE]
That would make me 10 years older than you, in theory.
I think you are still confused, you can drive up to 100km/h in 2nd gear without damaging your engine/drivetran, but in first gear, it will die, but it is possible, there is no physical locking device from you to do such a stupid action.
How about you go out now and give a try and tell me you can or you can not.
what has this got to do with bob_san?
he can't answer his own critics?
so you come in and be a hero for him yeh?
Oh no, Onion actually means from fifth to first at 100km/h. Read the posts. I' ve been through this before with Onion.
Not everyone here is technically minded or has the experience, to say things as they are, judging by this topic. There is enough misinformation out there. Sometimes you just have to say something. Sorry, I won't do it again.
Wrong. TOTALLY WRONG. Even with an ECU which cuts off fuel, ignition, launches a cleaver to chop off your right foot to get it off the accelerator pedal, you can exceed the limiter/redline/goodbye-line if you go into too low a gear at too high a speed and release the clutch. For example, going into 1st at 100km/h or going into 2nd at 130km/h, when the gear ratios have the engine at redline at 60km/h in 1st and 100km/h in 2nd.
If you double clutch, you can get into 1st at 60km/h with zero effort. I have done that to prove a point before.
The reason you need more effort to get into 1st at that speed without double clutching is because the synchros are trying to get the input shaft speed up to the same as the gear speed. Given enough time and wear, you can get it into 1st at 60km/h or even 100km/h if you are persistent enough.
I feel like an idiot now.... why I bother spend my time explaining all these I could learn another language by now.. :(
lol
thats what we needed, a green block gangster, backing up what we're saying
LOL x999999999999
lol it pays to hear both sides of the story before suggesting taking it to court or even the media. i work at a dealer so i have heard both sides of the story (not just bobsan's interpretation of it).
if you had heard both sides i doubt you would feel the same :wave:
SANTA3563.. hey.. was just wondering.. how much is the leather interior? ive been looking aroun but not much luck atm..?
I know this has nuffin to do with the damaged engine.. but why put a k20 from a civic when u can put in a f20c?
There is a lot of posts to read through - but why is it so hard to find an independent mechanic to look at your engine? What you really need is a report on the likely cause of the failure. If the report suggests that water ingestion or something that you contributed to (over rev) is the cause then you know where you stand.
If the report is inconclusive then you may have something to argue about. Until you get another opinion you are wasting your time.
You are definately not right in terms of manual Hondas. There are no "downshift" limiters. eg If you are in 6th gear at 120kph and then down shift to 2nd instead of 4th by mistake. Physics will dictate the RPM that the engine will spin up to on downshifts.
What you are thinking of is a fuel cut - on a downshift you can definately have a mechanical over rev.
'disappointed' is quite disappointing. name suits you to a tee. still can't believe that you been a mechanic nearly 28yrs. i think someone needs to take a course in modern mechanical engineering. i dont want to offend you, but you should read what you type before you post. most of it make no sense.
sorry i'm not in the position to post it up :)
how come?
yeah, why not? I'm sure everyone here wants to hear about it too, why not let us hear the whole story?? so far, we've only heard from one side~~
LOL @ Disappointed! ahahaha. Mechanic for 28 years, ferrrrkkkk mate!
Yeah post the story man! We all wanna hear it.
there is no other side of the story unless someone is able to get a Honda rep from that dealer to get onto ozhonda to have a vent-off with bob san…
why??
there are always two or more sides to a story, wether you hear it or not.,...
haha c'mon of cos there is, just that the other side of the story is highly unlikely to be revealed unless honda comes to ozhonda and tells the story..
i adsked around and spoke to a few honda technicians and sales , this issue isnt new apparently. Also has happened before
They said his oil was filled over an inch from the MAX position on the dipstick.
he had also taken photos of the oil spilled on the road and emphasised how much oil had spilled....then when they checked it was still full
the car in general looked like it had an extremely hard life, it looked like it had been thrashed, the interior/exterior was disgusting too.
after the dealer had honda aust involved and hond aust knocked him back there is nothing more the dealer can do (except offer to repair it as a retail job). yet the guy refused to get his car out of their workshop for over 2 months.
thats hondas side of the story APPARENTLY.
Gosh. Thats a fair whack.
What a pointless thread... Go to the wreckers and pick up a second hand engine for like under 2k.. get a mechanic to install it.. 800-1000.. and done.
"Extremely hard life" ... smells like bull. My last car had an extremely hard life.. and it was a barely serviced Kia engine... stull runs after 160,000 kms...
Meh... i think the thread poster isn't even reading this... he said he'd have it fixed soon anyway.
oh yes because he was dirty and didnt wash his car they shouldnt replace his engine. come on.
but the over filling of oil makes sense. why was it overfilled? and would that really cause an engine to malfunction?
yes it would cause the engine to malfunction
it would take more power to turn the crankshaft (engine appear to lose some power). however in extreme cases it may damage the seals and gasket etc.
but in bob san's case, i think the surplus oil was blown into the air intake manifold then it gets to cylinders together with the air. it gets burnt then causes the damage
and thats the issue i beleive.
the last service garage wasnt a honda dealer, so therefore they refuse to fix it under warranty
so, is it worth going back to the non honda garage and let them know?
where is bob san anyway? he seem disappeared~~
From his first thread yonks ago... it didn't sound like the garage/mechanic/workshop where he had his car serviced at first was willing to accept any responsibility for overfilling the oil.
Wow just read this whole thing.
Bob_san: what a douche-bag.
Disappointed: ROFL now I know mechanics are dumb but this is something else.
This thread makes me sad about the state of the world. Why are there so many idiots alive...
"I want a refund on this apple"
"But sir you've just returned the core..."
"HAVE GOOD WILL I WANT ANOTHER APPLE WAH WAH"
Modifying cars has risks, NEW cars in warranty even more so. This thread is a perfect example of how to act like a complete dickhead once it blows up in your face.
i reckon.. sue ur mechanic.. stop messing around with the honda dealer.. the mechanic overfilled ur car.. and this seems to be a major problem to ur engine blowing up.. talk to the mechanic. before u do any legal action.. =).. or illegal action.. jk..jk
what ended up happening to this guys car?!
Having read this, I wonder what we can actually do to our cars without nullifying the warranty. (Apologies if this is a thread-jack) The earlier precedent stated for warranties wouldn't apply here unless something similar was ruled in an Australian court.
Things like DIY start buttons, larger wheels, headlights... Surely they can't be voiding warranty?
ive fixed up the car and sold it since. its all in the past now. can't believe ppl still remember this thread.
ive learned alot from this whole ordeal. its been 5 months in the making.
i have spoken to countless people who bought new cars and have problems such as cracked steering colums, transmission failures etc. all from the same excuses saying they voided the warranty due to some ridiculous accusations. (overfilling oil? now thats a good laugh)
just a word of warning. it dosn't matter whether ur car is serviced at honda or not, modified or stock. once you run into a problem and you take it back to the dealer your screwed. They charged me over 400 dollars to take the sump off before they even determined if it was gona be a warranty repair or not. and the best part is they still coundnt determined what actully went wrong.
no matter how trivial the problem is they will most certainly not fix it even if its not your fault. the only way is to fight them. even if you have right on your side be prepared for a long and tedious fight.
shieett.. makes me think twice abt moddin my car now
ive just put on a k&n panel air filter.. went to get my car serviced and told em abt the k&n incase they 'accidenty' replaced it... and the service dude was lik... y did u change it?.. and i was lik, coz it more fuel effiecent and provides abit more performance, dont ever need another air filter etc. .. and he was lik.. nooo.. and in terms of warranty, if the k&n filter stuffs up and effects the engine.. then yes, warranty is voided
shouldve changed it to stock when servicing and changed it back afterwards.. now they know
Shieeeettt, People dont think this only happens with Honda, the amount of stories ive heard from new holden owners is amazing also.
I knew of this one poor bloke who had to have his LS1 replaced something like 4 times & another guy who picked up a brand new VE SS and after 2 weeks water started leeking underneath the dash.
The real sad part is from my experiance in the industry, working as a mech & attending Tafe and all that is that most of the time when a car goes in for a warranty repair its done half arsed, to the absolute bare minimum, minimalist amount of time & parts are used.
This thread now abbreviated on google in a form of another forum...?
i love this thread.
made me lol big time
hahahha dats why i wait till next year (warranty gone) then do some engine related modes :p
