1. A method for cleaning the EGR system of a combustion engine, said engine having an EGR valve and an EGR valve seat, said method comprising the steps of:providing an induction device having a member conforming to the EGR valve seat;providing a solvent to the induction device;administering the solvent to the EGR system through the induction device; andterminating the administration of the solvent after said solvent has been administered for a sufficient amount of time to adequately clean said EGR system. 2. The method of claim 1, wherein the solvent is atomized prior to being administered to said EGR system. 3. The method of claim 1, further comprising pressurizing the solvent being administered to said EGR system. 4. A method for cleaning the EGR system of a combustion engine, said system having an EGR valve and an EGR valve seat, said method comprising:providing a member through which solvent can be administered which conforms to the EGR valve seat on the engine;removing the EGR valve from the engine;attaching said member to the engine at the EGR valve seat; andadministering solvent through the member into the EGR system to clean said EGR system. 5. The method of claim 4, further comprising the step of inserting a gasket between said member and said EGR valve seat to form a seal that is substantially impermeable to fluids. 6. The method of claim 4, comprising the additional steps of:terminating the administration of solvent after said solvent has been administered for a sufficient amount of time to adequately clean said EGR system;removing said member, andreplacing said EGR valve.
