So last night i put on my off road h and after i started the car and let it run for a few mins there was smoke coming out from under the hood i could see it in front of the headlight. At first i thought it was just the wd40 burning off that i used to loosen then bolts but i let the car run and even drove it quick around the block and still smoke. Does it take longer ten 5 mins to burn off or do i just have a leak somewhere? I had an exhaust leak in a previous mustang and it sounded like crap but no smoke. This sounds awesome just smoking... OH AND THE BOLT I READ PEOPLE TALKING ABOUT ON THE PASSENGER SIDE HOW ITS A PITA, JUST GET IT FROM THE ENGINE BAY WITH A FEW 10INCH EXTENSIONS...SO MUCH EASIER!
