Exclamation Is this a blown head gasket?

2007 Impreza 2.5i, just under 100k miles. I started smelling coolant burning about 2 months ago on my passengers side but didn't see any drips on the ground. The oil and coolant look fine. In the past two weeks or so I have seen drops of coolant under my car and has overheated once because I was low on coolant that I was unaware of. See the pictures below:

Nice pics, looks bad for sure. I would be concerned about the overheat issue, many leaky Sube's,(like mine), haven't shown the overheat problem but even that is not a good indication that a bigger problem is not occurring. The HG issue is widespread and I think you gotta get those babies done. Keep your eye on the reservoirs for contamination too.

I wouldn't call it a blown gasket, the cylinders are still sealed. This is more of an external leak. It's not life threatening at the moment, so plan ahead for a replacement.

I'm in the middle of replacing mine with 6 star head gaskets right now, just bolted the engine back in tonight. Definitely change those be boys.

It looks like you still have a bit of time left but keep an eye on the coolant and plan to spend some money in the near future.
