NM35 Stagea I BLEW HER UP What a shame ;)

[Cohen]

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?

Just like you would do with a bike, pull the head and have a look, could just be a $300 fix.

Does sound like a head gasket or cracked block, neither of which are common

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

I'd ignore it and just drive it.

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?
