have you replaced the water pump? it might be that.
have you checked all hoses for any leaks?
Are there any leaks inside your car under the dash? both passenger and drivers side?
if you see no signs of leaks inside the car or in the engine comparment then it might be that your engine is cracked, due to overheating. It can be one of the cylinders that is chipped or it can be the cylinder gasket thats worn out. and it can be leaking into your engine, if so you will need a new engine!.
The same problem happened to me. i kept on fixing everything until i got tired, and took it at honda for a diagnostic test and they told me this

 

so basically, my life sucks.

 

You can try a new head gasket. That may fix it or it may just be a waste of money, if it turns out the engine is cracked or warped. Continuing to drive while overheated will almost always crack or warp the engine.

 

That's really unfortunate. Attempts at engine repair run the risk of throwing good money at a lost cause. You may want to look into getting the best trade in value in conjunction with the purchase of a new or used car.

 

I think my only options right now are to do a trade-in or to get a new engine. Dealer said 4,300, which means I can probably get it done for $2,000 at an independent shop. Even if I sell it after that, I might make money money overall.

 

Yeah, I understand. The potential risk is that the $2000 investment will not end up fixing the problem, and I am also not sure a mechanic could or would guarantee the work.

 

honestly i dont think its the best idea to get a new car. well it really depends on ur budget really.
i am in the same situation right now, wether to keep my civic and just buy a new engine or buy a new car. now if i buy a new car, im gonna be in debt and have to make payments more than 200 a month for about 4-6 yrs if u think about it. but if i fix my car and just buy a new engine i will be saving alot more money and i owe no money for my car. so i would be debt free once i pay the engine.
i found stock 1.6 b16b sohc dual stage v-tec for 700.00 and i know some one that is gonna install it for me in one day for 200.00. so to me dats worth it and better deak than buying a new car.
if you want i can give u the number of where i got the engine..its some place in california, and they gave me free shipping.

 

but yet again yes it is a great risk in spending that money and still have problems with the car, dats why a new car would be great! no problems guaranteed, and u have warranty for a while, so you know nothing is going to happen to the car.

 

I can definitely afford to fix it, I just hate spending money on **** like this. I got the car today, the dipstick was fine...I have no idea what they were talking about. The readout said:

Further diagnostic need as in line for tear down to review condition of cyl. head. If needed repair est for cyl head and above listed is $3,982. Additionaly to install correct radiator est. $516.

I found a local honda place (Lake Town Motors) that said he could probably mill the head and change the gasket for 700-800. I'm gonna take it there and see what he says.

 

I would ask Honda to provide a clear account of what they did and what they found to conclude that the head/head gasket is bad. This information above is very difficult for the lay person to understand.
