What happens when the previous owners use a race only airfilter for 45,000 miles?
Just purchased a 2006 C6Z and decided to check the air filter. Unfortunately, I didn't do this until after purchasing the car and getting it home. It was disintegrating into pieces as it was a haltech foam race filter from 2006. Instead of just changing out the air filter, I figured I better have a peek inside the intake to see if anything had happened running that horrible filter for so long. Yikes! I had to disassemble, degrease and pressure wash the intake and clean the TB.
holy ****! I can only imagine what's in the cats, let alone the heads...
it may be taboo, but on older non corvettes I've had success with seafoam intake cleaner....
I've seen it clean out a sludged up catalytic converter...
at least run a bottle of Lucas injector cleaner through it a few times....
also you're going to want to check the maf as well as the map sensors... maf is on the air intake, and the map is on the passenger side front intake manifold
make sure to use the proper cleaner for the maf, it's sensitive
Much of the oil in the intake was likely from the PCV system as it injects the oil into the intake before the TB. If it was raced on a road course, that pumps a lot of oil thru the system from doing 4K to 7K pulls, them closed throttle and hard braking, repeat 500 times per day. I pick up 3-4 ounces in my aftermarket EE catch can each track day and less than 1/2 ounce in 3K miles of street driving. Less from doing drags
I agree that oil in the intake is not due to the air filter however all of the contaminants and sludge stuck to that oil is due to the poor filtration from the race airfilter.

Perhaps almost better that the oil captured a good portion of the cotaminants the destroyed air filter didn't, almost like an oil bath air filter.
