Default Anti freeze on block

I just noticed that there are puddles of anti freeze on top of the block. From the looks of it it looks like it could be coming from around the knock sensor. Is it possible the sensor could be leaking anti freeze? Or is it not possible?

Make sure you clean out all of the coolant that is there and have the car idle afterwards for confirmation on where the leak is. If I had to take a guess it would be the water manifold gaskets.

okay thank you for your input. It looks like i'm going to have to take it to the dealer. I've spent two weeks replacing parts on this car and spending a ton of $$$$ sucks. i'm sure most people on this forum know what i'm talking about. You have to pay to play.

What year is your car? On older models (might be on new ones too), the plastic end tanks on the stock radiators will develop hair line fractures from the heat cycling. That's my guess anyway.. If you have any pics we could get an idea of any spray patterns that we may be able to see.

Check coolant lines to the upper tank. They dry rot really quick. If its bad cut that part off and reattach. Usually you have enough hose to do it.
