Default broken cam shaft

i have a 1992 Honda accord with the factory f22 engine. I was told that the camshaft is broken, i never had the car running or have had the engine apart yet, i got the car in a trade for some work done to another car. Is it easier to change the head to a head with a good cam or change motors, i have a spare motor that i know runs strong. thanks.

It is far easier to change heads, as long as they are the same series.
IE: F22B2 (non-Vtec) to a F22B2

Yep, I'd say get another head. The most common cause of the camshafts breaking is because of lack of oil to the top end; the camshaft journal is probably damaged.
Now bear in mind that the engine may have been run out of oil, so you are rolling the dice that the bottom end is going to be okay.

If it broke directly behind the Cam belt pulley, it's possible the Cam Belt Pulley retaining bolt came loose. Possibly from a previous timing belt job.

I got the head off today and the other head is ready to go on. Can the head gasket be reused or replaced, it stayed on the head and is in one piece.

Absolutely DO NOT reuse the head gasket, the valve cover gaskets or seals. It's false economy, and they will not seal properly.

why do some people say its ok to reuse them since they are not the felt type of gaskets?

It has to do with (basically) the relationship between the clamping force applied to the assembly, the 'crush' that's applied to the gasket (so that it may comply with any surface irregularities), the fact that rather than recovering from prior loads; the head gasket retains it's last dimension - so you'd have to apply enormous amounts of torque to ever hope to seal it a second time.
The only reusable head gaskets I've ever heard of are solid copper.
If "some people say its ok to reuse them " wish to chime in on this topic, be my guest.

got everything back together except for the exhauste. On the distributor theres a 5th wire that on my parts motor was used, on this motor I dont have anywhere to plug it into, is this going to cause a problem?

P you the man (and you knew it was coming ) but I'd have to disagree on the valve cover gasket. Sure you stand a higher risk of leaking but at worst you're going to have a very gradual oil stain. We're not talking oil gushing out or bad compression like with seals or head gasket. If it leaks you tighten it up a little or put some RTV on it, IMO its not worth buying a $20 seal set everytime as long as you're careful when you take it off. Ain't no big deal, if you got a show car or hate wasting a drop of oil be my guest and replace it...its not my money.

I'd replace the motor. Sounds like you got the equipment and the know how if you're asking in the first place. Like he said who know's what the rest of the engine looks like, might be oil starved as well. If you know the other motor is strong and doesn't have any other problems then don't mess with a weak setup that could have issues.

While I worked as a Flat Rate Technician, I had made a commitment to myself that I would do everything that contributed to doing the job correctly (and only once!), such as not reusing contaminated coolant, gaskets or (in this case) rubber seals.
Yes, I know that in some cases, it can be done. But I've found that over time and milage they get stiff and uncompliant.
Do what you want, but I'll continue to suggest what I feel to be prudent mechanical advise. To advise any other would be less that professional.
Why my attitude? Basically because of the lessons I've learned, and the fact I'm a lazy F&^*%K makes me go the extra step to make sure I do a job only once.

Regards P

True, the fifth wire is the hint.
Honda did a switcha-roo here with regards to getting a crank angle signal to the ECM for the EFI system.
Some, like your 1st engine (I believe); had a crank angle sensor mounted just behind the Harmonic Balancer Pulley.
Others, like your 2nd engine (I believe); had a sensor in the distributor which performed the same function
If I'm correct; you've two routes.
Swap over the required stuff from your 1st to thw 2nd engine or

I second the lazy f*ck part. In my case I just rebel and refuse to drive to the store, hence the oil collecting under my oil pan.

My guess was the 5th wire also. I agree with you P on replacing and not reusing. Usually I do this if the car I'm building is a show car or something I'm going to be driving everyday, but this one is one that I picked up in exchange for doing a motor swap for a guy and I just wanna get it going so I can sell it.
