Did you look under the car or just from the top? It may be dripping somewhere where you can't see it but not hitting the ground either.

Mine smelled too. Pin hole leaks at high pressures will aerate a coolant leak so you will get all of the stink and no obvious leak. Get some fluorescent dye and a black lamp (any auto parts store will have these) pour the die, run it, and this works best in a bit of darkness, flash your black light ( I got a cheap pen one) I recommend splurging the xtra 5 bucks and getting a solid black light pen because then you can use it to look for other leaks using dye like engine oil or refrigerant.

Thanks guys I will get the dye. The smell has gotten less and less So will see I do have one other question what tool do you guys use to get the back bolts off the valve cover Saying it’s tight to work in there is an understatement

I dont recall any special tools I used. I believe it was always just a socket wrench, and sometimes with a long extension on it.

Remove your battery, theres an access hole from the firewall to get to them
