well found head cracked

[eldo]

Sorry to hear that but a used head can be found fairly cheap. Do you have pics of where it cracked? (This is the first i've heard of these heads cracking.)

I am VERY sorry too, because I had almost exactly the same problem. Dooh. Including the valves being bent from a broken timing belt. Look at it this way, it's and excuse to do that B16 swap. Whoo Hoo!

Well, your story is exactly the same as mine....


Against all odds and teh advice of seemingly EVERYONE, the block was cracked between two and three. Ouch. So i got a short block from the junkyard and basically transferred all my new or rebuilt parts onto it. Now i've bascially got a fully rebuilt motor that runs execptional and gets well over 30mpg! It runs about 1/4 of the heat range on the temp guage, and if i'm in heavy slow traffic it might get up to 1/2...but when the fan comes on it goes back down to 1/4 temp....I was devestated and doubted my mechanical abilities when it first happened to me, i mean, after replacing EVERYTHING in it, only to still have it overheat...what a let-down. Yank the head off and scrub the crap out of the deck, and look very closely for cracks between the cylinders dude, i had to really hunt. But it was there, once it would warm up it would be fine until i got my foot in the gas...then the cylinders would walk and spread open the crack and allow cylinder pressure into the liner, boil/blow out the coolant into the overflow bottle, and overheat. It appears to be a problem with the early CRXs, probably the #1 reason they are in the junk yard to begin with, either blown head gasket or cracked block because some knuckle head drove on a blown head gasket for miles and miles because the temp gage went back down to middle-range because there was no water on the sensor to tell it how hot the engine was....uhhh....i shamefully raise my hand as guilty....the radiator developed a leak and i lost coolant on a lonnnnngggg road trip once, but i didnt catch the temp gage sky rocket and then settle back down until it was too late. She must have held together for at least 10-15 miles at 75-80mph with no coolant...she was a good motor, despite my idiocy...Now i'm back in business though....with a fully redone cooling system, life is good!
