It's difficult to troubleshoot with vacuum leaks, just replace the vacuum lines. All the lines can be replaced with the engine in the the car.

- The really tough one is the one getting to the EGR VSV. First, take a look at one of the other VSVs that are easy to reach and see how it disconnects, practice doing it by feel because you are going to do this by feel. If you have large arms get a lady, teenager, or someone else with smaller arms to do the reaching.

If those lines are cracked, you probably have other problems lurking. Check the soft fuel and vent lines, check all the coolant hoses including those that you cannot see running under the lower exhaust manifold heat shield, check the soft brake lines. Inspect the transmission cooler hoses, oh wait you cannot, they have a nylon covering so, just replace them.
