We are going to try and replace that and see if it helps.
yea coolant in oil or visa versa is the norm, but not the written law of a blown head gasket.

A block test kit to check for the presence of hydrocarbons in the coolant may be something to look into.

To preface I have a CAI, new plugs, msd coils, a off-road x-pipe, SLP exhaust, and few other that don't pertain. It is untuned and ever since the install of the SLP exhaust when we have a massive downpour or an impending downpour when the air pressure starts to drop and the air starts to chill the car will hunt for idle or just die entirely. Today, after two whole days of downpours I go to drive, start it up and it idle like crap. huge misfires that rocked the whole car, finely after a few seconds of keeping it alive it settles. I head to the road and tip in to the gas and can feel the whole car shake and bog with misfires and it feels dead but I press on hoping it will iron out when it warms up and dries out but when I get up on the highway the check engine light starts blinking. I immediately limped it home and it has sat since. What do you guys think I should do to stop this? any and all responses would be appreciated.
Bad MAF (MASS Air Flow sensor) in the intake or a leak in the intake could cause this too.
