Freeze plug popping out under boost.
So, I have about 3k miles on this engine and a few months ago, it popped a freeze plug out when rolling into boost. Once the weather got warm, I put it back in and it blew out again. I performed a leakdown test and it showed 30% 40% 45% 50% front to back. Seeing that, I replaced the headgasket. However, that did not fix my issue. Came into boost a couple of times and POP! Coolant exits engine. It is the freeze plug right above the oil filter. I put black RTV on it the first time and the second time I used high tack gasket sealer. Any ideas?
Thanks in advance!
