Easy guys I'd be grateful for any advice. Have looked about and have seen this issue on other forums but no solution is ever revealed. Just want to get it sorted early with minimum faff! :)
trying to keep it concise:
drove easy for 20 mins or so after a good warm up. Parked up no prob. Left it for half hour came back, warmed it up, easy driving then got into the motor way giving it some beans before I pulled intonB&Q
parked up got out and there was steam coming out the front with a sweet smell of anti freeze! Underneath of bonnet passengers side above the expansion tank seemed to be the most soaked with coolant, proper dripping from the right, but generally everywhere!!
called aa n the guy seemed confused. Took off the header tank cap and dos a pressure test. No leaking from anywhere, not the rad. Did it whilst engine on too, revving pretty high, no issues!
Dried it up drive it home steadily, 20 minute drive with motor ways. Aa followed. Got back n dry as a bone. Left it to coolndown for a few hours then warmed it up and gave it a quick 2 mile sprint up n down the hill. Boost fully engaged on several occasions. Git back, coolant everywhere again, from the same place from the looks of it.
Cleaned it up and left it a few days. got a new genuine sti 1.3 tank cap. Switched them over, Warmed it up, gave it some beans up n down the hill again. More coolant! :(
It's not over heating at all. It seems it's fine if you drive steady with no boost, but once you get going the expansion tank vents out the top around where the tube goes in. It's always wetter on the right hand side. The aa guy topped the expansion tank up because it lost a fair bit on the A12. I've not done anything to the motor since I've had it and as far as I can tell it's all completely standard mechanically.
going to get a sniffer test for HG but anyone heard of this before and know the direction I need to be heading, please link a brother up!!
:) thanks in advance
