Yeah...I guess now that you mention it, it doesn't have the most pleasant aroma...
Kinda like me after eatin' a big batch 'o Chili and poundin' down a few beers...[:'(]
Turqui...in response to your PM...(having a problem replying to it? )
Maybe you can get the Liquid in the can (not the spray ) and pour it over the engine to let it soak.
I save all sorts of re-sealable containers...like Cool Whip, or coffee cans, etc.
You could put the engine and/or parts in the container...pour the L.W. over, then snap the lid on and forget about it for a day or two.
