D15A2 Honda CRX HF (Carbed) 1984-1987


Ok, here is the story: Friend's little brother was driving, car overheated shut off (happened ~5 times). After that, the car would not start. It would turn over but not start. Anyways, got it towed to my house and pulled the plugs. Cylinders #3 and #4 had detonated so bad, that parts/sections of the electrodes had been detonated away. I did a compression check 80-40-95-95. Pulled the head and luckly no piston damage or cylinder wall damage. Can see where the headgasket blew from a water jacket and cylinder #3.

Anyways... here is my question: The head has a crack, from the spark plug hole?? The hole that is visable from the bottom of the head in between the 3 valves on each cylinder. I am not sure how deep it is or how bad. But what should I do about this? Does the head need to be replaced? Can I get a pressure test done to it and see if it is still good? The car is worth junk and basically not worth putting much money into.

Here are pics:





Sorry for the poor quality, but it might help out a little.

Thanks for the space.

Oh and just for a laugh about how dumb this guy is: his first car, a blazer.. he burnt the clutch up, and rolled it in a ditch within a couple months of getting it. He then got a grand am, ran off in a ditch and messed the front up and the axles/suspension the second day after he got it, then a month or two later the motor siezed in cause he did the same thing; his grand am kept cutting off (about 6 or 7 times because of overheating) and finally it will not turn over anymore. Now after a couple months of this car, he does the above.

 

i wouldn't risk it.. more then likely the head is toast.. u'd spend 20 bucks on ahead gasket put it all together and it might not even run still.. 20 bucks down the drain.. and 2 hours of labor for nothing.. guy sounds like an idiot.. you'd think he'd learn his lesson??? sorry i have no pity for ignornes

 

Anybody else? Are there any other heads interchangable? Or just the A2?

 

That looks like a 12v motor, so any carbed head should be interchangeable. The FI head does not have CVCC equipment. I believe the Hf originally came with an 8v though, so that may be a FI motor, in which case you should look for any Si head. I can not remember the engine codes right now.

Oh, and remove your "friend's" driving priviliges (sp?).

First, not my friend.. My friend's brother.. I would never have a friend like this.. lol

It is a 12valve carbed motor. I just would like to know which heads I could use, if any others besides this one that came off of it, so when I go to a junkyard I will have a few more options.

 

After some research you have a DX engine there, so look for an 83-87 CRX Dx or the civic equivilent. An Si head does not have CVCC and so will not work.
