After being recently serviced my 1999 truck is now "leaking" oil... the level is within the acceptable level and the people who did the service claim the truck is "designed" to drain off the excess. They claim the 2000 and newer trucks have a "oil recovery system" which is drained during oil changes but the 1999 can just "spit" this excess on the ground... however for $120. i can buy this system... am i just being taken??? i cant imagine the EPA going along with that type design...
