Then crawl under the engine and have a listen. I had visions of fuel being pulled into the carb and was going to back off the rockers but I got laxy, found the leak and called it done. 69 Super Bee, 93 Mustang LX, 04 Allure Super

Or hook up a vacuum gauge...if the needle has a consistent drop in PSI thats usually a sticky/misadjusted valve Last edited by chache876; 09/04/10 01:33 PM.
