The green stuff is coolant.

Coolant isn't pinkish on these? Strange! (new clueless owner, can you tell?) Assuming the front cover gasket is a common issue, estimated cost of repair in the pacific NW?

The front cover gasket is about $10 and most shops charge 4.5 hrs to reseal it. Some RTV for the oil pan, new coolant oil and filter and your good to go.

I wouldn't assume it's a front cover gasket. That first picture can be leak trickling down from a bunch of places. I can't tell where that second one is and what the Ghostbuster slime is.

I chased for 8 mo a coolant leak to find out my brass reserve tank was leaking.

Check the easy stuff first... hoses, cracks etc. Then if you really have to drain the fluid, change out as much as you want/can.

Pressure test the cooling system, Napa makes a nice test pump. Just don't go over 15 psi. Pump it up and you'll find the leak. You can also use this pump ( the one with the inflatable Blatter) in the small radiator opening to test your radiator cap and overflow tank.

x2 you can rent this from autozone for free ... you leave a deposit which they refund when you take it back. The pump is worth more than the deposit ... so i kept mine.

This will help force coolant out if you have a leak and you should easily be able to trace it.

I always assume "Ghostbuster" slime is coolant/oil mix. Could mean bad things....

Based on the second picture, I would guess the intake gasket, not the front cover gasket. What is that gunk in the second picture?
