If this is a head gasket my time with this car may be coming to an end. I don’t have the skill to do the job nor do I have the money to pay someone to do it.

I do occasionally get a code for the crank ventilation system, and I know short trips and excessive idling (both of which I’ve bee doing in the past month) can cause condensation in the crank case. Those two together might be enough to cause what I’m seeing, but I have to accept that this may be something worse.
