That sounds very bad, cracked head could leak coolant into the cam cover, from there it could end up in the catch can.

Ther is another posibility, which may be a little less worrying. The reaction of petrol (mostly octane) produces carbon dioxide and water vapour. You could be getting blow by (CO2 and water vapour) and the water vapour could be consensing in the catch can. I would have thought that it would have boiled off again (and ended up being scavanged throught the intake if you have the scavanging system operating).

It is hard to tell which is more likely without seeing the car, I'd need to know:

1) did you find the water when the engine was cold or hot.

2) did you find it right after the engine was running or had tha car sat around for a while.

3) how much did you find

4) could you tell if it was coolant or plain water.

5) is there way the water could have leaked in (is it a atmo vented catch can)

It will probably become obvious if it is a cracked head before long so lets hope thats not it. Blow-by is no big deal, even new engines have it, just gets worse over the life of an engine from wear, eventually could require a rebuild.

I don't see how a blown head gasket could leak coolant into the cam cover.

SLY SKY: open up the cam cover (or even just the oil filler cap) and have a look around,

can you see water? (lets hope not),

can you smell water? (got a strange musty smell usually)

is the oil milky at all (maybe drain the oil and check).

Get back to us and tell us how it went.

It builds up say after 2>3 weeks, its clear not green. About a cup full.

My water level is always the same, at oil changes everything looks good if a blown head gasket the water in the radiator should drop. I thought it might be condensation. I don't know. :alcoholic

Clean as looks normal, oil fine. :burnout:

Its only condensation mate. Totally normal during the winter months. From the responses you've received thus far I'd take it the other guys aren't running a catch can.

Sleep well tonight.

Thanks dude, youre right it has only started doing it in the last few months. :thankyou:

hi mate, my 33gtr has a cusco tank on it and it fills twice a year about a pint. done this for the last few years. never loose,s water no oil contamination. if you do short bursts and it damp weather the engine will absorb moisture from the atmosphere as it cools. normalyy [without a catch tank] it is sucted into the turbo and burned, but this lowers the air density in the chamber hence less power, catch tank takes the moisture away from the turbo.just empty it and carry on as usual. hope this helps..............bernie/uk.

"EMPTY THE CATCH CAN"! I didn't know you had to empty it as i did an oil change the other week and i didn't even give it a thought. Mine is a GREDDY can, (side mounted) is it just a matter of disconnecting hoses and tipping upside down, or do you have to take it apart?

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
