I have taken my truck into several mechanics and they tell me the same thing my right exhaust manifold has a leak. My truck makes a loud noise and sometimes slow acceleration and sometimes cuts off on me at a stop. Last mechanic I took it to actually looked at it and it bolts ad nuts had been replaced but one of the nuts had come off so that is most likely the reason it has the leak. So basically I need to know how to replace the gasket. Because all the places I been to have wanted $200.00+ to do it and I just can't afford that. Also my check engine light has not come on and I drive this vehicle everyday.

I attached the procedure with pictures for you.

I will warn you, it is a tight area you will need to access.
