Hi, need some help here
since i rebuilt my d16Z6 i had a lot of problems that i solved, but now i don't know what can it be.
Engine starts and sits RPM at 1k and then lowers to 600, while is warming it starts spitting water and steam out of tail pipe and finally stalls. If i let it rest for hours and try agan it starts just like nothing.
I Don't know what it can be, oil is not mixing with coolant, something that i noticed is that is missing those 2 coolant hoses on intake, more than that is all good
My car is a Honda Civic EX 1995

You need the 5/8" bypass hose. You can do without the smaller 5/16" hoses that warm the IACV and throttle body unless you live in a VERY cold climate.

How much water and steam are we talking about? Your exhaust will spit out some water, as it is a result of the combustion process and moisture in the air. If it's just a little bit of water / soot / steam, you're probably fine.

Does it smell like antifreeze? If so, then you have an issue with coolant getting into the combustion chamber somehow.

The stalling issue may or may not be related. Is your check engine light on, and if so, what codes are stored?

 

Well, looking at the intake it seems like where the hose was missing is where it was leaking a lot of coolant because intake gasket went bad


the gasket was wet all over that part, i assume it was because the pressure of coolant, and that was sucking coolant to cylinder 4

Don't know if that was the cause of stalling but is a problem to solve after all, i think that because of cylinder 4 getting wet, ecu sended more fuel to the other 3 to balance and end up flooding cylinders

At the time i didn't have any CEL code. Now i already bought a new gasket, RTV and a hose, only need to put it all together again and see if its fixed

Well, seems like leaking problem is fixed but its stalling anyways. Don't know what it can be, because it don't overheat, no hard start, no bad idle when engine is cold, no bubbles on radiator, no oil and coolant mix and i rebuilt it so i think it can't be the head gasket.
Any ideas? Has someone had this problem?
