    i have a 95 Tacoma 2.7 5sp 4x4 with 204k. my exhaust manifold was cracked in two so i decide to replace it. everything went fine. i had to buy new stud bolts for the exhaust flange. i bought them at advance auto in the HELP section. around every 75 to 100 miles i have to tightened the studs up cause there is an exhaust leak at the flange. i tightened the studs up and the leak goes away. any ideas as to what is causing the studs to become lose? i have tried lock washers and lock-tite. i am lost as to what to try next. please help

    try getting bolts from the dealer, or reusing the ones you already had? Maybe the aluminum is expanding faster than the bolts, letting them back out?
