Hi guys, having trouble with my WRX, First off my radiator had a crack in the side, so i replaced it, went for a 5 minute drive, allgood so far. Turned car off then about 20 seconds later water started gushing out the overflow bottle, lost about 90% of the water in it. So i thought i burped it wrong, so i reburped it, was going allgood then water level rose alot and quite fast inside the funnel and then started boiling everywhere again (out the turbo resovior tank as cap was off) I was thinking it had blown a Head Gasket, so i checked all the common symptoms, no milky oil, no oily water, no white smoke out the exhaust, there was a tiny bit of water but i assume that its condensation as i tested it in the morning, no bubbles coming out of radiator when cold. so i thought id do a compression test, i couldnt do it while engine was hot as one of my coil packs broke on removal to check for coolant on plugs, so it can only run on 3 cylingers till new coil pack arrives, so i did a compression test, 3 times on each cylinder and readings came back at 157, 153, 160, 151. this is a cold reading as i cant get a warm one at the moment
Any help or ideas would be much appreciated, thanks in advance
