Ok, so continuing the problem, i changed all new steel turbo lines to band new steel turbo lines AGAIN because when started, it looks like water/coolant is running from there. Changed the turbo coolant hose that connects to the back of block. Drove and found it it was not it. Lost a bunch of water becase it was misting and jetting out like crazy from a leaking water hose.

Next day, i went and changed out the heater hose. Started up fine and everything was good. test drove it and heard a weird sound and a little chatter from under the hood driving 3 miles back from test drive and lost a hole bunch of power. came to a stop at a light, car died, and couldnt get it started back up. pushed it all the way back home, like almost a mile away. Push started the car and i knew my turbo blew. Let the car sit for like 4 hours, took off intake pipe, and found some water droplets inside the line that connects to valve cover. Thought it got in somehow when i was adding water to radiator and fan blowing it all over the place.

I then checked radiator, low on water/coolant. Drained some, and there was no water/oil mixture. Checked the dip stick several times and looks like no mixture either. Removed spark plug, and spark plugs are wet and little bit of water inside the cylinders, from what i can see.

Now, i thought blown head gasket and blown turbo, but my brother said it could be from blown turbo. leaking or blown seals blowing water through turbo into the intake valves into cylinder. It sounds correct too, but i dont know. What do you guys think???

btw...the guy i bought it from said s14 t28, but it does not have a garrett serial number so im thinking it was a fake garrett with garrett turbo housing.

Your brother is an idiot dont listen to anything else he says

water CANNOT leak into the charge system throught the turbo
water only runs threw a passage of the turbo to cool it, there is no seal for the water to leak into the intake system

you probably didnt bleed the air from the system causing it to overheat and blowing the head gasket.

do a compression test

^^^Thats what i thought too, but, i did bleed the system, everytime i added new water/coolant.

So most likely its a blown hg right? No other way for coolant into the cylinders right?

right, compression and leak down test will give you your answer

the only way you will get a chocolate milk looking oil is if the engine was running for a while with a blown headgasket.

My KA had a blown H/G oil looked fine, till i replaced the HG and ran it for a few minutes.
