I have noticed that the coolant was seeping out of the radiator cap, i undone the bleed screw at the matrix, thermo & rad. Little coolant came out of the matrix and throffy bubbles came out of the thermostat housing. Tons of coolant and bubbles came out of the rad bleed screw and the coolant overflowed out of the cap point. I done up the rad bleed screw but could hear noises so i opened it up and it blew steam out as high as my garage roof under some serious pressure. I then heard a knocking noise and turned it off straight away SH*T i thought. But has plenty of oil and there is still coolant in the reservoir tank albeit a low amount. I noticed mayo in the oil cap but i dont use the car and have not done since last september so thought it was down to that. Is this hgf? I'm not sure where the knocking is coming from? That is a worry.

Sounds like air in the system somehow.
You really shouldn't take off the cap if its already trying to escape!

Bleed it through properly then see how it goes.
