Engine issues URGENT

I just swapped an h23 bluetop (50,000 miles) into my 5 gen Prelude and had it out for the first time today. I accidentally misshifted from 3rd to 2nd at about 7300-7600, it continues to run full power. When I came to a stop light, the car shut off and wouldnt start without the accelerator depressed to bring it to a 3k idle. Doesnt sound like anything is wrong, no hesitation above 3k. What could be wrong? Timing jump? Ive accidentally misshifted engines that were pounded into the ground before without anything happening, and this engine only has 50k on it

no one can say if the 50k is right or not and remember that if its not maintenanced right it doesnt really matter does the engine has 50k or 150k!

it can be abused 50k engine as well

Importer had written on the vc 72k km which is 50k miles. These h23s are from auto accords with a 6500 redline, they cant be too beat. The inside of the engine, and out look flawless.

so if I write 20k on my engine it must be the truth then?

of course they can be. poor maintenance and lack of driving skills = beaten engine

all what Im saying is that its wiser to be skeptical than blindly trust things what cant be proven

Just curiouse how you slam 2nd from 3rd? A little excited or bad shifting/double clutching combo? cant say ive ever done that, but it sounds like timing. if u dont hear anything awful than it didnt jump enough to damage anything,yet. Pull the timing cover tell us what u see and smell lol

Everyone on Honda-tech is saying bent valves, but its not making any noise. Also its a very common misshift thats why its called the money shift. I was pumping full of adrenaline from "racing", looked over at another car, and missed the shift

I'm not exactly sure why that arouses your curiosity considering 2nd is right next to 4th and when he went to shift into 4th, he slightly pulled the stick to the left and the tranny went into 2nd. It's probably one of the most common miss-shifts.

ibbentvalves

The engine is getting too much air to idle/cruise, but it is being masked with RPM when you rev it. Probably aren't bent bad, otherwise you wouldn't be able to get it running.

Shift from third to fourth with your palm facing the passenger. Palm facing you is how you easily mess up. Or shift palm facing directly down with four fingers bent at a right angle. No more speed shifting time will tell all truths

Compression test done, removed cylinder head. Exhaust valves are bent but very slightly and they just barely scuffed the pistons. Looks worse in picture.

Agreed.
All except there arent any syncros to downshift. My family has been building variouse race motors/cars since before i was born and ive never seen it. Thats why, must be a rook driver aka if it wasnt beaten it is now

I give the OP props. Mad props in fact. He fukt it, admitted it and is taking action playin no games. I see no reason to point noses to the air. How many can own up to a silly mistake like this.

I honestly think this issue is much easier to happen due to cable shift mech and not direct shift. You have hardly any feeling of whats going on in the transmission (b16 love )

I hate cable shift response. If the tranny and cable mech has any wear you are so much more prone to kerfuk it when trying to "go fast." Ive trashed second gear popping through gears

It's a fairly common event in the Honda community. Much more than it should be.

Friend of mine money shifted two different Preludes.

Actually had a guy (I didn't know him, highway encounter) money shift his friend's Celica GT next to me on the highway. Owner was sitting in the passenger seat when it happened.

Not so sure here. Synchros are for downshifting and upshifting. Its how gears are engaged at the correct speed for a mesh without grinding. Hence why you can go shifting at whatever speed you desire without any extra effort. Although one may shift at the correct speed that can reduce the work required of the synchro. Less work is less wear

Yup >


The selector slides between two gears. It has a synchro (the gold colored ring) between the two gears that selector has access to.

Only reverse isn't synchronized.

Yes, of course synchros are there, its not like engagement differs up to down. but they are designed for an upshift ...and the flywheel weight and compression also play roles here we dont.need to get into. even still in a properly maintainedl/correctly functioning vehicle I have never seen or experienced it. Sorry wasnt bashing, i was just curiouse vehicle malfunction or driver error. Either way just look at it as a sign for a better build or maybe a non interference motor

This is why, besides the vast amount of people on h-t to offer information, I like this site better than honda-tech for civil questionnaires and answers. Everyone on h-t acts like a bunch of jackasses. See for yourself, heres my thread on h-t, go to the second page.
