Ok so ive figured out I have an exhaust leak, thought 1 or 2 bolts were maybe loose. Pulled the heat shields of and 50% of that bastards are loose. So I tightend all that I can get to. Here is where my problem comes in. There are 4 bolts that holds the manifold to the back of the turbo (pretty sure that's what the parts r called) Now I can only get to 1 bolt with a spanner from above the motor. I can fell with my fingers that 2 are loose and 1 has completly fallen out. What I would like to know is, is it possible to reach these from underneath the car? If not what has to come off to access and tighten them? Or do I have to take it to ford/mechanic to get these all tight again? Also seeing as this has happend a few times, are there better bolts I can get that dont come loose as easy?
