So i decided to take the heads off on the rallye to see the head gasket and well uhhhhhhh...... yeah

pics say it all.....

 

At least the heads dont look bad and i think i might be lucky on the rebuild for this one. but still havent seen the bottom end or anything of that nature obviously.

Any idea on what can cause this besides a cracked head gasket?

 

OUch.... Nice start to the new year, eh... Were the head bolts tight? I can understand a blown head gasket causing leakage into one or two cyl, but all? I hope thats all it was.
I assume you did drain the coolant from the two block plugs before you pulled the heads. Right?
What happened to this motor to make you dismantle it? I only know the story on the H/O...

 

From my restore thread.

 

I must be missing something here.

Other than slightly different combustion in number 8, all looks good, as far as I can see.

Combustion chambers c normal amount of carbon for a running engine, rods straight, nothing unusual about the lifters, aftermarket head gasket will need to be scraped off and replaced, but that's normal.

I would probably have drained the coolant first, but it does come out one way or another when you take the engine apart .

Uhhh sure.... Dang it, i always for get about that thing and i also pulled it out while it was in the car....

 

So the coolant is just from me not draining it correctly? Cause that would be awesome . and also by looking at it does it seem like the engine wasn't rebuilt.

 

If you did not pull the block plugs, then that was what did it. And looking at two of your pictures, there is coolant in the block still.....
When you cracked the head seal, the coolant drained into the cylinders from the lower passages.
Given the position of the coolant in and out holes, the lowest point for drainage is not at the lower radiator hose (like what one would think).


Now - go get that water sucked out of your engine....
And change the oil afterwards...

 

I am so on it right now!!!!!

 

Tom , it looks like a .30 over piston in the photo if i am seeing right; The the head gaskets do not look like steel, so most likely a rebuild... but don't worry if you have to go .60 over , these 350 S will take it easy... maybe it was cutting out because of fluid wetting the plugs. The bearing sound that increases at power could be a washed out bearing or even a lifter if your lucky. Best of luck . sorry to see this mess for you.

 

Great!
We don't want to see a "pistons stuck in bores" thread tomorrow.

 

It looks to be a rebuild the rallye 350's had a 10.25 to 1 pistons with a very small 7cc dish if im correct.

 

X2, if you had that much water in it while running you would have hydraulicked it and bent/broke a rod, cracked a piston, something. Looks like it's been rebuilt.

 

Yup. Number 8 looked a little fishy, but all the water in the cylinders is from dis-assembly. Also looks like maybe not enough antifreeze? or is that GO-5?

 

Thought i was crazy for a second there......I said to myself somebody didnt drain the block and heads and was looking for a crack or something......Get that water out of those cylinders asap btw.....

My .02 pull that motor out and go thru it completly......Better safe than sorry,If water got into the pan and you ran it, problems will surley a rise.....
