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?

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
