h22 in 93 accord help

[ACEE22Accord]

Ok, I have a 93 accord and I did the h22 swap in it. I have the h22a1 from the 95 prelude, everything bolts up right and was cool. Recently I've been having major troubles with it. The car would sturter really really bad. So we changed the fuel pump. We put a Walbaro 255lph-HP. And the car still runs like crap. When the car first starts to run it runs fine. Then once it warms up it starts to sturter. At first it did it every blue moon. Now it does it consistently. And today the rpm dropped to nothing and the car killed. The timing is advanced all the way b/c at one point that was the only way I could get the car to move so I could take it to someone, so they could look at it. And now I can't find out what degree the timing should be set at. If anyone can help please email me or post answers to this thread. Right now any help or suggestions will help.

I would have to look at it. Sounds like something is definatly wrong but I dont have a good way to diagnose it over the internet. I wish I did, id be a gazillionare.

At first glance it sounds like you have a mechanical timing problem. I would first set the engine to Top Dead Center (TDC) then remove the the front engine cover to expose the timing belt and water pump belt; then I would make sure that my front, rear balance shafts, and cam sprockets are are lining up to there marks.
If the timing checks out then you must ensure that your fuel injectors are lined up perfectly into the head.
Check to ensure none of the spark plugs are cracked (Usually from overtighting)
Check your vacuum system (refer to your vacuum diagram)
Check the compression on each cylinder (3rd stroke of engine)

I would look at these areas first! Without seeing the actual setup or knowing how envolved you were with the swap can only limit me to some of the the main possible failures.

Well I never got a chance to do all that. The timing belt broke, and well since I have an interferance engine, it's a good possibility that I bent my valves. And well I need to know who makes some good inexpensive valves. Or some good valves b/c I think to get some new ones. I was looking at crower or skunk 2, b/c I was also deciding to get cam gears and cams. So...if ya'll can help I would really like it. Thanks

The head will have to come off and the bent valves replaced best case scenario.

It is possible that you didn't bend any valves; it all depends on how fast the engine was turning (generally if you were below 3000rpm then you shouldn't have bent any valves.

I don't know how mechainically inclined you are but I would go ahead and replace my timing and water pump belts (make sure all timing marks are lined up), do a valve adjustment and start her up. Now if your paying a shop to do the work then you should go ahead and let them send the head to a machaine shop so the valves can be inspected and if need be replaced.

Now as for some good valves, that depends on what your planning to do with you ride. If your planning on putting in a radical camshaft then yes you will need new valves and springs (Usually when you purchase the radical camshaft they will sell you the required valves and springs)
If your just replacing the ones that were bent with no change in camshaft then ordinary valves from your local shop or parts store will be fine.

I Hope this helps.

check the injectors/fuel rail/FPR, distributor.

I don't know too much about this kind of problem but I had the same thing happen when I rebuilt my old motor. I am going to pay attention in this thread and if I can help Ill say something. Good luck though that sucks.

If the timing belt broke, it is not likely that you missed the vavles. H22s are VERY close and there isnt a spot where the cam stops that all the valves are closed like other Honda cars. The best way to tell however is not to put on new belts and "start it up" It is to do a leakdown test. This will tell you not only if hte valves are bent but which ones and in which cylinder. It takes much less time than alonnzo's method.


And since this is the Honda Ghandi forum. I would apreciate it if the misinformation was kept to a minimum in here. People look to me for help, not crap.

I understand your method, and is also proper but I'm just giving my point of view so there's no need to be rude.

IN MY EXPERIENCE I HAVE SEEN SEVERAL HEADS FORM H22'S WHERE THE TIMING BELTS WENT WHERE THE MOTOR WAS RUNNING UNDER 3000RPM AND NO VALVES WERE BENT.

That may be, but for someone to go through all the trouble of replacing the timing belt when you can just do a leak down and save yourself the trouble? You are more than welcome to express your point of veiw, really. But if you are going to contradict my posts in MY forum please be absolutly certain that you have an argument. You dont know the circumstances of this poor guys situation any more than I do. Thank you for your time and thank you for trying to help.

If you are an actual mechanic you would agree with me on this point, 99 times out of 100 the H22 will bend the valves, even if its just slightly. If the belt is broke, it takes 10 minutes to find out if they are. Throwing parts at the car to "see" if it damaged is a waste of every ones time so its not even worth mentioning.

Well. I won't argue with this man..
Especially since we worked at the same honda dealer at one time..
HMMM 99 out of 100? that sounds pretty close, since all 100% I've seen break the belt on this motor also bent valves...

Not sure how old this kid is But I bet I was rebuilding blown H22s when he was still wacking off to the jacket of his new Vanessa Williams CD in the bathroom at school.

I have seen and done several that were running more than 5,000 rpm and were moving at 70mph or better with no valve to piston issues at all! Lucky there as these engines are interferance engines with no room for mistake! But yeah the leakdown is best like ghandi said!

Holy revival batman. this thread dies twice in the same lifetime. :rofl:
