Coolant and overheating issues.
Alright guys i have had this problem for a couple of weeks and it has me tearing my hair out at this stage.
If i go out and do a couple of hard runs it starts puking coolant everywhere and the alarm goes off.
Now i have double checked and checked again and the hoses are the right way around.
I have done both a compression test and leak down test and both are perfect.
The engine has been apart recently and the cylinder and head were both decked and a new head gasket put on. No signs of water in the oil and cylinders as well.
I have just pressure tested the cooling system and i put 15 PSI in to it and there is no leaks. I have also checked for blockages and nothing.
The only thing is the cap starts to bleed off pressure around 10 PSI. Is this normal?
I have changed the bottle i had to another complete bottle and cap and still have the same drama.
Any input before i pour petrol on it and light a match?

maybe your thermostat is stuck?.. it's like a car tstat.. i know its very unlikely but i thought i'd throw it out there... it sounds like a head cracked or gasket leak but you've already elim that.

Go back and re check the head and gasket, just cause you replaced it doesn't mean it's not the problem. Start from the begining and check everything you did.
