Water in all the cylinders?

[khryslerkid]

However we are talking about this happening while the engine is running. First off, when running the exhaust valve will be opening and any coolant in the cyl will be pushed that way. With all the air and fuel rushing down the intake into the cyls keeping it running somehow coolant was moving in the opposite direction? Held a journeyman's ticket for 40 years now and can't say I've ever seen that happen.

I unfortunately hydro-locked the engine after its first start in "many" years. Car ran for 1 minute max

Sounds like he was lucky that it started, maybe on just a couple of cylinders.

Funny how I can consider myself lucky lol. Engine issues appear to follow me around a lot. I guess I am lucky that way lol.

I don't remember reading anything about the history on your engine.

Has is ever been exposed to freezing temps without the proper antifreeze? Looks like from the rust, it was mostly water.

Have you checked your heads for warpage with a good straight edge?

At this point, I would break everything down and have a shop cook and magnaflux the block and heads. If everything checks out then you can freshen everything up and you'll know what you have. I hate mystery motors!

About 6 years ago we all voted for them to be yours.

Yes, a cooling system, especially if pressured up when the engine is shut off, will fill everything with the engine not running. And it would have to fill the cyl with the crack until it overflowed that cyl and started to fill the intake. And the exhaust valve on the cracked cyl would have to be closed Unless the exhaust ran higher than the intake as in an upswept header).

Hardware is different. It can bounce around.

Well I stand corrected, a nut can go where water cannot. Thank goodness for your 40 years journeyman experience. Now I know it was just my imagination.

Water in ALL cylinders.......did you park in a lake?

Years ago at a GM dealership had a knock come in with same thing. Was there and then gone, this was warranty work. Pulled the heads and saw numerous small knicks in pistons(more than a couple) and put it back together and no more noise. Whatever it was went out exhaust I guess.

The fact that liquids move differently than solids didn't take my 40 years journeyman's experience to figure out.

Trying to picture pouring antifreeze down the throat of a carb of a running engine and see it gushing back out.

The next time you see a liquid flowing in the opposite direction to the air and fuel rushing towards the 17" of vacuum attempting to pull it into the cyls, you want to be sure to record it. There's physicists all over the world that would want to see that one.

I know and understand how magnafluxing works and also the use of dyes to detect fractures on the external structures but I have not seen how shops do pressurized testing. Do they have a special jig or fixture for selective sealing? Is that a more objective test for structural leak detection? Is it more cost effective?

Nothing special about it. Actually pretty simple.
Block has a water jacket around all the cylinders. They just block off all exits to the jacket, apply air pressure, and watch for bleed down. No bleed down=no cracks.

 

[wyrmrider]

we had special plates but you can use your torque plates with some rubber gaskets or even stock gaskets
but sometimes cracks only open when hot
most likely something simple with a BBM
it's not, for example, a 400 sbc

 

[Moparfiend]

Thats what I was wondering how to block off all the water jacket holes in order to do a pressurized leak down. The concept is simple but the execution has to be done correctly.

Good point about high temp vs cold pressure testing didn’t think of that....

Update?

Update?

Update coming soon when I finalize the build plan I will let you guys know.

I do have some brake questions that I am going to post .... would like to get your inputs!!
