No - you should read what you wrote. You have a missing gasket on the intake side so not sure how you corroborate that with a leak on the exhaust side. Yes. the outlet is integrated on the INTAKE manifold but it's a separate chamber. It's more likely you have a major head gasket failure if you coolant in the EXHAUST manifold..

as in, under full boost it throws water into the cilinder to the exhaust manifold

#

U talking about this part of the intake manifold

#

If you have no gasket coolant can leak

subtle minnow
#

the square ports are coolant passages. If you have a cracked intake manifold gasket or something weird it could leak into ur intake

#

So it could suck up some coolant and burn it causing the white smoke

#

While your inspecting your rb check all the coolant lines and gaskets. The lines (oem) tend to get very weak and brittle very fast which causes coolant leaks. When I pulled my 25 head off for my 26 head swap I was surprised by the amount of coolant stains on a 45,000km engine.

Coolant is quite corrosive sometimes, so a line leak above could have done the job.

I would still get a new gasket it though for the intake. It’s like only 70cad

#

Your turbo is water cooled right?

#

@subtle minnowTurbo is an Holset HX40 with custom turbine, it's just oil cooled.

#

Cilinder 2 is wet from water so spark plug won't ignite

#

It's running on 5 cil, because my intake gasket is literally non existent

#

What I'm doing right now is getting my intake manifold machined and powdercoated for looks, ordered an OEM intake gasket and new coolant

#

going to do that first, and check for leaks and what not

#

coolant level way super super low after the white smoke curtain

#

almost nothing left in my radiator

#

exhaust manifold^

#

you can tell that around cil 2 there's literally nothing on the water channel

#

previous owner really fucked up here

#

just checking what it did

#

and it seemed like it was burning the coolant that was located in my exhaust manifold

#

and the steam was coming (presumably, I'm guessing here) out of the turbo/heat wrap

subtle minnow
#

Other than that, not too sure on where the coolant could be coming from

subtle minnow
#

That shouldn’t cause it not to fuel or spark

#

It should just be running rich a bit if there is a boost leak

#

Btw do you drive your rb without a air filter? I wouldn’t do that. The cylinder head and valves are very delicate

If it’s fixed with just an intake gasket

#

that’d be neat

#

What ignition system are you using? Are you using a stand alone?

That’s exactly what I mean. Are you in Europe?
