Hey, I'm in a bit of a sticky drama, by the looks of things my motor is kapoot.
only recently bought it and its looking like my head gaskets are done for, I've got massive pressure in my cooling system,
I've replaced;
Thermostat
3 Coolant flushes
Radiator cap
Replaced the top turbo cooling line as it blew up hence how I noticed the issue.
Car doesn't overheat at all. but when I rev the motor with the coolant cap off it overflows massively.
When I take the car for a 3 minute drive and take the rad cap off, it basically explodes coolant (doing it with a rag and slowly releasing the pressure don't @ me).
Do you guys have any other ideas
i can do the job my self as I am a motorcycle tech so I've got the knowledge of fixing it. just want to know if I am better off replacing the whole motor for a lower k motor (i only have 160k's)
or replacing the head gaskets. and what other gaskets am I looking at needing?

You would do a combustion gas in coolant test to be sure, then pull the heads off and go from there.

 

Slim to good chance what you describe could be caused by not being bled properly. Randomly taking the cap off isn't a diagnostic method that's particularly useful.

so I've just got a burp kit to try and burp the coolant or see exhaust gasses, and no bubbles whatsoever, then I got the missus to rev the car to 2k rpm so I can watch for bubbles, low and behold, coolant nearly overflowed from the burp kit, but hundreds and hundreds of bubbles all smelling of exhaust gasses came out, no white smoke from the back at all no loss in power nothing, doing a compression test soon as well but it's 100% head gasket

 

Just curious as where to get most of the gaskets and what gaskets I'll need

Cant mate, its starting to blow coolant lines.

 

Yeah that's bad. 

Heads off time.  Fix it, don't buy a random engine and hope for the best

I've just bought all the gaskets from amayama justjap, now to start the tear down process and install a full headstud kit from arp, manifold bolts and head bolts

Did you do a TK test?

    • If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
    • Lock me in mate, although I'm not sure if I'll be heading up from Goulburn or down from Sydney, either way, return will be back to Goulburn 
    • Sounds good, we will aim to be there! @The Bogan I'll give you a shout if you are heading up to campbelltown for the meet too.
    • Before I get to the test day, just to finish off the android head unit. This is a demo from car start up....the standard/host system takes a few seconds to boot (same as all v37) but Android comes up quickly. In this vid I'm using the delivered launcher but have set the default to Agami since which is easier to navigate when if use primarily 5 apps. You can see the host system still takes over when required eg putting it in reverse, and you can switch between Android and not by holding the back button 3 sec. It is pretty responsive (fast) but you can see I had to press harder than expected a couple of times.  I still have the phone connected to the stock system, and that also seamlessly takes over Android music playing. v37-android-demo.mp4 The bigger reason that I put this in though is so that I can use Ecutek directly on the head unit. That gives me a dash with logging (up to 20MB only), high and low value warnings on any parameter etc etc. I've run a USB cable from the Ecutek OBD dongle to a USB input on the unit, easy. v37-ecutek-demo.mp4   The unit did freeze on the launcher the other day, I think Agami was trying to verify the license when it didn't have a data connection...will monitor and report back if there are any other problems but so far I'm very happy with the upgrade.
    • Nah that is just crappy GPS mapping, I did have a small excursion (cold tyres, damp track, surprise!), will post up that when I get a chance.
