so,there i was checking for an air leak on my brother's F150.
i could hear it,but couldnt pinpoint the source.
i grabbed my carb cleaner,with the little plastic noodle on it.
sprayed here and there and couldnt find anything,moved over to right side of engine and proceeded to spray some more and to my dismay,it lit up.
entire engine compartment was engulfed in flames.i walked around to the driver's seat and revved up the engine to blow out the fire,fortunately it worked.
the vapours made contact with the leaking exhaust manifold,i guess it spurts a little fire on the exhaust stroke.
i have also use water ever since.
it will make engine run rough,and on most occasions the leak will make noise
