How do you fix the seal on leaky spark plug tubes in a 1997 dodge neon 2 liter sohc?

Intake manifold gasket...a friend had the same problem (same year car) and we fixed it a couple of weekends go, so far, no leaks. It isn't too big of a job, just like advertised in the Haynes manual. ==New Answer== A little more helpful, you might need to replace the intake manifold gasket, OR it could be you need to change your spark plug tube seals. That in itself is real easy and you can purchase the seals at any autoparts store.
