HERE IS THE ALBUM OF ALL THE PHOTOS I TOOK! PLEASE VIEW THEM.
So recently, we bought a 1995 Honda accord LX 2.2 L for 100 dollars from our friend.
He said that his car doesn't start but it cranks. And it all of this happened when he tried cranking up the car on day and it wouldn't start.

So when we recieved it, we checked for everything including if the timing belt works, distributor, fuel pressure ..etc then when we got to the sparkplugs - we took out all 4 sparkplugs and the last sparkplug was damaged. - it looked like it's been smashed by something.


Here is a picture -

More pictures are in the photo album.


Then we opened up the head cover and we noticed that the last that one of the intake valve springs were broken for the last cylinder where we found the broken sparkplug
-


With that, the two exhaust valve springs were more compressed / in than the other exhaust valves for the other 3 cylinders.


After that, we decided to open take out the cylinder head to see underneath.

We found out that the last piston was slightly cracked.
We took a look under the cylinder head where all the valves were and the last valve is really messed up. The valves rods are bent and everything looks really messed up.

The last piston



Under the cylinder head (for the last piston) -


Any ideas what we should do now? We want to fix it up with minimal $$ spent.

Every stuff for the cylinders look fine except for the last one.

Buy a used engine; they are reasonably plentiful and relatively inexpensive.

 

I think all of this happened because the intake valve spring broke and caused a loose in the intake valve and rod and the piston slammed into that causing all of this?

I mean the timing belt is fully intact.

What we're thinking of doing is putting a new piston in from the junkyard and buying a new cylinder head..

 

It's most likely better/faster/cheaper to buy the whole motor.

 

I think that you are right about what happened. Broken spring, then the piston bent the valve and smashed into your other valves. This mess broke the piston.

You might want to look for a used engine. Search car-part.com for junkyards with your engine. You can search by price or distance. You may be able to find a low mileage engine for a decent price. You will find that rebuilding the top end and repairing pistons may get expensive.

How many miles are on the current engine?

 

196k miles

My dads seriously thinking just to replace the piston and cyl head lol.

 

Bad idea unless you want to spend more money and have a car with an engine which most likely vibrates and burns lots of oil.

 

I have to agree with the others - even if you replace the piston and rebuild the head, it might work but you have to deal with "unknown" issues - you never really know how it ran before this happened.

A replacement F22 engine should not be that much - do the maint items (t-belt, balance belt, seals, ect before install).

Now if you want to really go there, the F23 engines (6th gen accords) will swap in as well. You didn't give, or I missed it, the trim level of your car so there might be a bit more to that swap.

By far the F22 replacement is a simple plug and play - the F23 is a bit more.
