34 neo head replacements

[K3nnyq3]

Hi.
I think my cylinder head has a crack in it, as i started seeing coolant in one of the heads cavities near intake manifold. 
So im thinking of getting a new one. 
Question is, which ones fit? 
Its rb25det neo engine with a turbo.
The rest of the car is pretty much stock.

Will r33 rb25det head do the job? What other options do i have? Or may the leak be coming from somewhere else? I have a very poor picture of the spot where the coolant is (1st cylinder from the front of the car, right above intake manifolds bolts). Leak is excessive enough to drip on the alternator from there, but i can't notice any coolant level drops in radiator or expansion tank.

Try getting your head repaired first.

The chance of that being a cracked head are sweet f all.

Clean it up and figure out where the leak is coming from.

More likely to be coolant leaking out the intake manifold gasket i'd have said, eg lower left of photo?

I'm with all them ^.

And you have no option but to use a Neo head, should you get to the point of replacing it.  An R33 head will not work.

Hmm. ill try to clean it all up and start her for a short while. Maybe it will give me a better idea about where the leak is coming from. 
It also does this... sort of like a relay klicking sound while under boost. It can be heard while idling too, but quietly. Only with warm engine. Maybe somehow related... if there is a crack in the head?

From that part of the head?  The VCT solenoid lives there.

Im not entirely sure where the ticking noise is coming from. From driver's seat it feels like its actually coming from the left side of the engine somewhere.

Ticking sound is more likely to be broken exhaust studs caused by a warped manifold 

[K3nnyq3]

Oh i already like the sound of   all this... intake manifold, exhaust manifold, head.... 

[GTSBoy]

RB engines usually have broken exhaust manifold studs after they've been in service for a long while.  Replacing them is an exercise, but normal enough.

Put it this way, if you have to take the hot and cold sides off, it gives you an opportunity to inspect, clean and replace a lot of shit that can give you grief.  It's not all bad.

Well, some good news. Just for the others to know who might have similar problem the coolant is actually leaking from the bleeder hose. I did see some coolant marks near there before, but i assumed that's from the last bleeding as it looked dry.  Higher revs revealed the truth tho. 
Even with warm engine i couldn't hear ticking. Ill try again next time it take her out for a spin as working under load seems to bring that sound out.
Thank you all for the replies tho. Very nice community. 

I would still like to keep this thread active til i find the source of that clicking noise.
