Howdy all. Just doing a routine check around the engine bay of my R32 (RB20). I decided to check the cooling system for air so i was running the car with the bleed screw on the inlet manifold removed. Basically the coolant that was coming out of this hole was very very foamy. I checked the coolant in the radiator and its not oily at all.

Is this a sign that i've done my head gasket?

take the cap off the radiator and fill it up, are there any bubbles coming out? does the car overheat? have you lost alot of coolant? If you are in doubt go to any radiator place and get them to check it, peace of mind over lots of work.

I filled it up just then when i was checking it. No foam or anything around radiator cap. Car doesn't overheat. Temperature gauge normally reads halfway or slightly above.

However the car did over heat on a trip back from Sydney a few weeks ago and it overheated once last year when i got a crack in one of those tiny water lines under the inlet manifold that was impossible to find! :P

turn your heater on if your car over-heats, it'll allow more coolant to flow through your radiator, thats just to get you out of trouble to get you home.

unless you saw milky kind of crap in your radiator and its not constantly overheating then i dont think you've done a head gasket.

      Who has a Infiniti Q60, Q50 (V37)?

      Yep, it was only an option on the Q50 Hybrid.  Same in Japan as far as I know. And doesn't use a centre diff like the Suby's do, so not the same as the WRX.  But it also isn't a reactive AWD like other Nissan AWD vehicles are, eg. Murano/Xtrail/etc.

      You should have got a Maine Coone then. Only thing is they're big. But so cool, and just like a dog. Or, just get yourself a high performance dog. That'll teach you for wanting Parkour indoors 😛

      Are you thinking of Bens R32? I don't remember if his went through the bonnet itself, but it went through the chassis rail. Brad (RISKIN) bought it, and turned it into a track car. It's funny how anti people are of Jim Berry now. I remember when I pulled mine out (during an engine change) and inspected it and found it cracking badly. At that point in time so many people were even on SAU, were so pro Jim Berry, and that was after Bens GTR exploded his quite publically.

      That's one of the reasons I got that breed, they look weird, the other reasons are they small, they are very vocal, and run around like they are on crack, I didn't want a breed that just sits around, these two are like kids on red cordial  My daughter has one, and it's a laugh riot, constantly doing Parkour around the house, sits on her shoulder, plays catch, and constantly runs around the house taking turns chasing the dog around, her Bermese though, just lays around with constant bitch face, and just looks on in utter disgust at the cat and dog playing together

      I'm getting PTSD flashbacks seeing that name again.  With my turbo swift, I got 1,500km of street use on a Jim Berry clutch before it exploded and took out my input shaft with it.
