Opening engine after knocking!!

First thing first. My English is not perfect, please excuse me if I am giving someone headache trying to understand what the .... I wrote. I will try my best

Okay I am kind a new to the forum. Yes I fell in love with Prius. That is why I have 2 of those. Both 2010.
The one I am discussing here has almost 200k miles on it now. Bought it with ~160k miles on it everything was fine.

Almost two months ago it was around 6 Am when it was around 40F outside. I push the start button and the engine knocks, it continues not for more than 5 sec. After work I start googling and figure out that this is a common issue even with a new 3rd gen Prius. Something to do with the intake manifold I don't know what exactly and if someone can explain that to me I will be really thankful. That was happening almost every morning when it was chilly...

A month after the knocking started I noticed sometimes it will knock and the ride will be rough even when the car is warm( after driving for a while in the city). That is when I decided I will bring it to the dealership and will ask them to replace that manifold(if that was causing the knock).

So booked an appointment for Wednesday( it was Sunday night when I did that).

Monday morning of course there is knocking but not only that, there is a lot of white smoke coming out of the exhaust. It was cold again I knew this wasn't the normal steam coming. After the end of my work day I start the car yes there is knocking and yes there is a lot of white smoke. So that is when I decide to go right to dealer and not wait till Wednesday.

Two days later they call me and say that it is probably a blown head gasket and there is coolant in the oil . They haven't open anything but for them the knocking is coming from the crankshaft bearings ..( I do not agree with that)

So there advice is to put a new engine in the car which will cost around 8-9k. They said there is no point of opening the engine and fixing it...

I told then I can not afford that right know and I took my car back to my apartment complex. So at that point I decide to either fix it my self, part it out or put a new engine myself(used )

Today is the fourth weekend I am working on the car. finally the Head is down...
Yes there is water in the cylinders. The head gasket looks just fine I don't see any cracks or anything. But from my knowledge I do know that there can be micro cracks where we can not see just with our eyes. I don't think that there is a cracked engine block or head as well.


So my questions to the forums are: Where else I can get coolant coming from and going into the cylinders ?

The whole intake manifold seems pretty complicated to me ...it has coolant inside which makes me thing that it has to do something with that.. but not sure..

I will post a link with all the pictures I have so far..

I will really appreciate your help.

Thanks

Since I had the car the only light I saw on this car was for low tire pressure. And a week after the issue started yes I did saw a check engine light one morning looked the code and it was "P" something which was related to misfire in cylinder 2 or 3 (can't remember exactly)

yes there are some 3rd gen engines out there but kind of pricey.. + I don't think I have the man power to replace it myself...

This is the knocking which is pretty common to 3rd gen. I looked it and I read many places that this won't harm anything because it is just misfire.

Yes this is true. I am sure 99% the knocking is caused by misfire.. There is a video on youtube that a guy figures out that if he disconnects one of the coils it will do the same knocking which proves my theory that this knock is not from the bottom. If there is a knock from the bottom it will be always there.. Where this knock happens only when the transaxle fires the engine then it is there for 5-10 secs and it is gone..

I do understand that coolant and oil mixture is bad but I would like to figure out how it ended up there ...

The video in my google drive is from the first week the knocking started..

The video bellow is not mine.

 

I haven't added any coolant. For the 20-30 miles the car was driven it ate almost the tank of coolant. Oh yes the oil was worse than milky. like baby poop....Yes you are right about the new design if I go that way I have to get the newer one. So yes that is my point I was having an issue which was common for those cars but I can't see it will go so bad ?? I don't see how the condensation or even water in the intake manifold will create this situation that I am facing know.

 

yes there is once line coming from the block to the intake that is a coolant line for sure. There are two lines on the throttle body which I have no idea why are there they had some pinkish drops.

I will see if I have time for some more pictures tomorrow after work.. To show you what exactly I mean

This is not my intake but mine was similar the yellow circle is the line where a small hose is carrying coolant from the engine block to the intake manifold( I do not understand that at all) mine is as bad as the one on the picture

 

Yes I know ... I said there is a guy on youtube that clearly shows that the knocking is coming from a misfire

 

Hey there everybody. Engine is out. Will be looking for a new used one. One question. My drive axles poped from the inner cv joint...not a big issue but would like to know what is the grease/oil in those so I can close them.
I will attach a photi. It was prety liquidy..
