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?

    • Hows your intake piping? Are you still running stock? Having in the stock AFM position would mean, if the BOV was shut/venting out, it'd create the almost stalling kind of effect right // "the rich pulse behaviour" due to MAF thinking air is flowing ? But this would be better than having the bov in the stock position + MAF on/just before cross over piping right?
    • Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card stile AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had not flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).
    • So to summarise, the best thing to do is to move recirc to between turbo and IC, and maf on the crossover pipe. Meaning I'd need a recirc flange, drill a hole in the piping on turbo outlet area. And drill hole on crossover to fit/weld maf sensor? Either that or put the MAF on the turbo inlet right?  Is an aftermarket recirc/blowoff valve recommended? Do currently have family in Japan so could probably bring something back with maybe a cheeky lil SuperAutobacs run?
    • Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.  
    • Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.
