The manifold is a large hunk of (usually) rusty iron off the side of the engine. It bolts to the block. If you can feel gas (air flow) coming form around this area, you have a problem. Check closely, because the turbo/exhaust piping can also leak with the same symptoms. The gasket is inexpensive but it may be a couple of hours of labor to change it. If one of your exhaust pipes is old and rusted, some- times they have to be replaced as part of the job... that starts to get more expensive. Bob
