hello all! just wanted to see what kind of opinions I get with my current situation. I have gotten my hands on a cheap 95 lx 4 door with a h22 swap already in it. however, it had jumped time and lost power. after re-timing and running a compression check I have found that all but 1 cylinder have 0-25psi. so, after doing just a little research, I've come to the conclusion that I need to either A: swap in another motor or B: try to rebuild this one or C: try to part it out and cut my losses.. I'm still not totally certain what year the h22a is, it is a serial #1008142. what are your guys' thought? any opinion is appreciated. thanks!

Welcome!

Pull the head off and replace the bent valves (or have a machine shop do it), inspect for other damage while apart.
Pistons will have kiss marks from the valve contact but they usually are ok.

Is it an H22A or is there another number after the A? Check here:
https://en.wikipedia.org/wiki/Honda_H_Engine

Contact the previous owner and ask questions.
If he did not do the engine swap, maybe he can connect you with the one who did.

yea man, just got the head off the car few min ago. really not that bad at all btw! but unfortunately, all but 4 of the valves are leaking lol.... so bare minimum is head for sure now. from the little bit of research I've done.. it seems it's almost as cost effective to just buy a whole motor vs rebuilding and repairing this one. am I right? all the cylinder walls seem to be ok but number 4. it has a score in it that doesn't seem to be terrible.. but it is there. thanks again for the welcome and I'm gonna get this sucker running. just may take a bit to save up lol..

Nah, I'd take it to a machine shop and just replace the bent valves.
See if they can figure out what year or year range the engine is from?
You got a car with an (I assume a JDM) engine swap, you don't know anything about the engine (not even the year it is) and you are not going to get another JDM H22A easily or quickly.

Someone probably paid a lot of money to do the swap.

I'd say to fix what you already have. You already got the head off, it should be a cake walk if it did not break any valves or guides.

A few hundred dollars for valves and some gaskets and a timing belt job might get it back on the road burning fuel, instead of a couple thousand for another engine or a machine shop rebuild.

Is it deep enough to hang a fingernail in?
Sometimes scores are found in cylinder walls. If none of the valves broke and the score is not right where a piston was kissed, I'd guess the score was already in the wall before this happened and it will run fine when you get it together.

the year stamp on the engine block is 91. the serial number is h22a 1008142. and the trans is a m2f4. gonna check around for a shop around here for sure. kinda out in the boonies in TN. the pistons actually don't seem to have any nicks or kiss marks in them. which I did find surprising when I pulled the head off. I have quite a few pics. I know a little about a little.. not a lot about a lot lol.. but I'm here to learn some and thanks for the replies so far!

H22A with no suffix number should be a JDM engine.

I can't decode the serial number, nor do I have info on casting numbers but try some google for that.
I'm a dealer tech, we don't normally see cars this old and we normally only deal with 100% stock cars. Others here may have more better info though.

yea I looked at that as well. from that I assume it is a jdm 1992.. the date stamp on the block is a 91 however.. maybe it was produced in 91 for 92 model year cars. if I had some pretty decent measurement tools I'd try to get the stoke and whatnot and try to figure it out lol... maybe in the near future i'll try that out lol...

thanks man. I'm gonna have to get some precise measure tools and give that way a go. I can't come up with any other way to really tell them apart lol...I haven't taken the "dizzy" apart. I guess that's what everyone is calling it.. looks like a distributer to me lol.. i'll try to get to that maybe tonight.. maybe tomorrow. thanks again.

ezone

Dizzy = Distributor for British?
Don't try to take it apart any further than removing the cap and rotor. You may create more problems than you wanted.
DO make a match mark across the castings so you can bolt the distributor back in the exact same spot.

ttamrekab

yea, well now the problem seems to be finding somewhere to have the head rebuilt. I can't think of anywhere around here that would do that kind of work. may end up having to send it off to someone...and it seems i have a jdm block h22a with a usda p13 head on it. why the hell these so confusing with all the different combos lol..
