Am i unlucky

[xmanz]

Am i unlucky in the fact my 07 v36 at only 63,000k has done a head gasket as bubbles come up and push water out of radiator.  So is this just a thing thats happened or what may cause this?  probly looking at 2500 nz  thanx ill no go and be depressed...:)

You may be unlucky as to the fact that your clock is probably wound back if the head gasket is done at "63k"
 

[xmanz]

its not wound back it came direct from japenese showroom 400k on clock certified

[Ben C34]

then yes you are unlucky.
How well did you look after the car? ever change the coolant?

when did you buy it?

 

[xmanz]

the car has been maintained at every maintaince schedule last big one was all brake fluid all coolant  auto trans filter engine filter oil etc.

i bought it in 2007  but its used only for longer trips 

[DashyyPC]

Doesnt mean its the headgasket though.
Just means air has gotten in at some stage, Loose/Worn radiator cap seal etc

 

Sure headgasket is the most common here but doesnt 100% mean it is.

Where do you live? Should be able to fix that for less than 2.5K

so coolant has been changed recently and now it's got bubbles... perhaps it wasn't bled properly? i though headgasket results in oil/water mix not bubbles?

Just air bubbles? Have you considered that maybe you just have air trapped in your coolant and not a blown head gasket?

[GTSBoy]

Acid test the coolant.

[xmanz]

i took it to a reputable mechanic who pressure tested the system and his advice was the next stage put air compessed into cylinders which will tell the truth i guess 

[GTSBoy]

No, the next step is to use a coolant tester to find out if there is CO2 dissolved in the coolant, forming acid, which tends to be proof positive of a blown headgasket blowing combustion products into the coolant.

[The Max]

Agreed. If there are no obvious signs of oil mixing in with the coolant, the coolant itself needs testing first. It'll be a lot easier than what your mechanic is proposing. He's jumping the gun a bit there.

Well, yeah, most of it - certainly at least the top part. The VQs are chain driven, yes? But pulling timing covers off is not the difference between affordable and not.

i got a bit lost on last part of your statement       ( But pulling timing covers off is not the difference between affordable and not.)

Do you mean remove the front of the car? Hell no. Take radiator out? Quite possibly. But that's not expensive work. Neither is removing the timing covers. That's what I meant when I said "But pulling timing covers off is not the difference between affordable and not". If it adds an hour to the job it's an extra hundred buck or so, right? Not an extra $500.

ok that sounds not too bad is the timing cover one piece or is there a top section thats not behind pumps and  things...

btw i had a search for v36 workshop manual  and g36 for 2007  cant locate any ideas

I dunno. I'm an RB user.

Google image search and have a look.

When it is all fixed I  would have the rad fan checked (I would think they are a clutch fan) blow a head gasket in our D.Max at 130K and five years old. Don,t rely on your temp guage I  ran a scanguage 11 in our Isuzus and that how I seen the temp rise, nothing showed this on the vehicles temp guage.
