oil in air filter duct work
1993 240, 212,000 mi, manual trans., non turbo. I recently noticed excessive smoke (oil). It happened all of a sudden. Then I noticed an oil leak comming from the left front of the vehicle above the AC compressor. Removed the air cleaner and duct work to get a better view, and found approx. 4 oz. of oil in the duct work. I believe the leak is from a small hole in the duct work, since any lines below it are brake related. My question: Since this is vacuum, how is it possible for motor oil to accumulate there? Possible cause and what to do to fix it.
