Then we realized that the bolt that was put in was too long and it bottomed out making it imposable for the housing to seal properly.
I contacted you and told you about my findings and it was only at this point that you told me that you replaced the old water housing which was not installed by me with a new housing because the old housing was leaking. Just wonder why you failed to tell me of this prior to me discovering it and pointing it out to you.
The bolt not seating properly Clear indication that the engine was driven this way for some time because below the bolt the trany is steam cleaned.

That bolt as well as the water outlet and most hoses were replaced AFTER the engine was overheated badly. The reason I replaced most of the coolant system was to make sure that it was not the problem. There was no obvious leak in the cooling system, but it was loosing coolant somewhere (maybe out the tailpipe), and I wanted to make sure that it wasn't the cooling system that was leaking.
The reason it was so clean was because I cleaned the engine bay after I replaced most of the coolant system AFTER it overheated. Because I was originally so sure that you could not have made a mistake and that the headgasket could not have been blown, I replaced almost all of the cooling system to make sure that it was not the problem. I cleaned the engine so that if there was a problem, that it would be easy to tell by where the mess was. I used green coolant and it makes a mess that is easy to see (trust me, I know, I spilled alot while replacing the system).
Chris states that it is exceptionally clean because it was "steamed clean" by the coolant. If coolant spilled on it, it would have left a large GREEN MESS or green stain. Notice in his
pictures that there is no green mess and is instead "exceptionally clean". This is because after I replaced most of the coolant system and cleaned the engine bay, there was no coolant leak from the cooling system.
Yet I was still losing coolant and starting to overheat when boosting with no signs of an obvious leak?
What are some
possible causes to this? Is a blown head gasket one of those possible causes? Is it usually the first thing to check for? I took the car to a shop and had them test for hydrocarbons in the cooling system. I watched them perform the test. It very noticeably came back positive for hydrocarbons. I even have a receipt that shows the test was done and that it had hydrocarbons in the coolant. I believe Chris even saw this receipt as it was in the car when I sent it to him. Yet Chris says that the gasket formed a perfect seal even though the head was warped and twisted. He even says that there were no hydrocarbons in the coolant.
You will notice that he immediately blames the fact that motor blew because of that bolt that was too long. This bolt was a brand new Toyota bolt purchased from CraggieB of IronToad Toyota. I would think that a stock bolt should be of the proper length. I asked Chris if I torqued the bolt down all the way and he said that "The bolt was fully torqued down and bottomed in the hole." Please see the email below. Notice that even though I told him that it was replaced AFTER it overheated, he still blames the original problem on this bolt.
When I asked him how the correct bolt would not fit correctly he said that he must have gotten a block that had a cross-threaded hole. This was a block that was given to him by someone else. It was not my core. Yet this is somehow my responsibility? I suppose that I should take it up with Toyota as he told me to do before?
