what I thought was a head gasket leak on my LBZ and thoughts and getting prices on a reman engine..well today
I got under the truck with a scope, and I found a drop of antifreeze what looks like its coming from
a "plug" on the engine, it's a 3/4" plug not a bolt it is next to the oil filter adapter. any idea what this plug is ?
More importantly does it go into the cooling system....I hope.

dont think I can get a picture of this plug, my scope doesnt have the ability to take pictures....

thoughts.......
