which there would be if the head gasket was blown, the liquid chemical changes color. It will sense the slightest bit and is very accurate.

I had a similar leak and I changed the seals using Paul's procedure on audipages. Problem solved.

I would just clean spray the engine cleaner foam in their first, then hit it with water.....it will clean everything up.

Then monitor it....I wouldn't worry about that.

Its making a decent puddle after driving. I would say like 2 table spoons or so.

Doesn't look too serious at the moment, but I'd keep an eye on it. Also, you can have an external oil leak from a head gasket without finding water in the oil or vice versa. There are four main types of head gasket failures:
1. Oil to outside engine
2. Water into oil
3. Oil into water
4. Combustion products into water

So just because you don't have water in the antifreeze doesn't necessarily mean the gasket is good.

Then I would clean it and monitor where it is coming from
