For a while now, stopping quickly after starting the car in the morning, a puff of white smoke comes up from above the left fender. And Ive noticed recurring puddles sitting on the LIM shown here, when engine is both warm and cold. I always use form-a-gasket along with the paper gasket on the water pump flange so im 95% sure its not coming from there. Below you can see obvious water marks on the aluminum. This pic was taken an hour after running. What made me post this was the car had sat for two days and when i went to park in the same spot there was a small puddle of coolant.
(1). Always water there, the most there of them all
(2). I loosened the bolt and put form-a-gasket on it then tightened it, havent seen moisture there since
(3). Appears to be moist there alot.
(4). Sometimes moisture, obviously evidence in the watermarks.
The 1st area has a bolt in there too and i also tried the trick i used in bolt 2, but no dice.
This leak isnt large enough such that i have to add coolant, coolant level remains same for the last year.
Advice/Comments? Thanks Guys.
