Car is a 87 with the 3.8. Changed the air filter today on the old bird and noticed what appears to be some oil collecting in the housing. The filter was dirty but as I drive the car alot in some not so nice roads I change it every few months regardless. It didnt appear any dirtier than usuall but never noticed oil before. Any suggestions are greatly appreciated. Thanks.
Check your PCV and the vac line to it...
