My 97 Dodge 2500 just developed a bad oil leak at the rear of the vacuum pump. At 98,000 miles, I thought it would be covered under the warranty. However, the dealer checked and tells me it is not covered. They want $900 for a new one just to fix a leak. I know I'm not the first person to have this type of leak. Does anyone know what seals are required to repair this. Dealer apparently does not service the part, just replacement only.
