I think I found the problem, check the pic, you will see the red circled area shows a spot which correlates with a coolant channel, there is black carbon here which extends to the edge of the combustion chamber, the other three corresponding ones on both heads are light in color. So I'm thinking this is the spot where combustion gases are escaping into the coolant. I am also going to crack test the heads just to be safe though.
No I can crack test them myself, I just have to pick up the kit to do so. Once I get back some money on the purchase of the 73 NYB I will do so.
The heads I checked before I rebuilt the motor, being that they were done in Massachusetts before i got the car I went over them myself. But yes i did take a steel ruler and checked diagonally, longitudinally and width wise in multiple locations, perfectly flat mating surface on the heads. I will double check the block too. I have my hands full at the moment though.
Yup I gave the block a close look as well, nothing showed up, I still have to check it for flatness though. That will come.
I've not used this, but I've used the regular Evapo-Rust. It works, especial if you forget that you're soaking something like I have a tendency of doing. I would've been tempted to give this a try last year when i was flushing my system. IIRC this stuff comes from Abilene, TX.
I think you are off a bit. That price only applies to formals.... If you have decided to give up on the car, I'll give you $2500 for it. . .
So, $250 then? Formals are nicer right?
Then why do I have 3x that in my car, and it still isn't finished? I guess I have an expensive maintenance program.
Nobody was saying you can have a done car, at least one done right, for $2500 - that's just your buy-in. And once it's done and you've got 20K into it, it's worth $2500 to the next schmuck.
I finally got enough money o buy the Magnaflux kit which is now in the mil, once I get that I will check for cracks in the heads before putting them back on. Then I can call myself broke again.Gary: Are there any updates yet regarding this problem? I figure you have probably been working on it. If you have decided to give up on the car, I'll give you $2500 for it. . .
$2500 you say ? Hmmm......Gary: Are there any updates yet regarding this problem? I figure you have probably been working on it. If you have decided to give up on the car, I'll give you $2500 for it. . .
