Stop in for a cup of coffee

Judging by the outcome of all this, I'm starting to doubt the 'experts' on here ...

IDK why you are running a t-stat for a 10 min test run anyway.

Also, the by-pass hose would let the coolant flow just fine even if the t-stat was in backwards. I suspect it either wasn't pumping properly or you didn't get all the air out of the system. I can't see the video, but if you weren't using coolant and the system had air in it or wasn't fully sealed...boil-over.
 
The whole equation discussion makes me laugh. It's only about how the equation is entered (written) into each OS that gives a different answer in each. The real question is what is the equation trying to solve for, then you can determine how to enter it into each OS to get a correct answer (excel would require an even different equation structure).

Note that the equation is entered into the phone and the calculator slightly differently. There is an extra space in the one on the calculator causing the OS to interpret the terms differently.
 
... and as Dave pointed out, I could very well have air still in it. I did run it without the cap for a long time and added maybe half a gallon after that.

you didnt have your overflow connected, that would have prevented a gyser :poke::lol:

I really don't know how the cooling system of a car works. I do have coolant in the system, though. 50%, the blue kind.

Well, maybe 30% after all the water I've added.

its a low pressure system. The only thing the puke tank would do really though, is keep all that from spraying everywhere. It also lets the cap vent properly, especially if there was air in there. Ive always ran the engines without Thermostats and the cap off the radiator, roughly half full to start with, to help flush the air out of the block and system. I think Dave is probably right, full radiator and a big Air bubble, equaled geyser. Dont feel bad, I've had it happen too

So the puke tank would be pressurized too or should it be vented?

And I don't feel bad. I'm a novice and I'm not afraid to admit it. :)
 
After the engine had cooled a minute or two, I thought I'd crank the engine over a little to try to circulate the coolant a little. I disconnected the coil and cranked.

The engine coughed and backfired. I suppose the heads were hot enough to ignite at 10:1 compression.

Is that something I should worry about?
