Yes...you are on the right track. A couple of the guys have cleaned the oil from the new filter, and then sprayed a very fine coat onto the filter. The purpose of the oil is to catch any dust that may make it through the filter. I talked to GM about this filter problem today, and was told that if you are going to the aftermarket CIA, you need to put a dry filter on it. All it takes to freak out the MAF is one speck of oil. Yes, it's that friggin sensative. The other thing I was told was to apply a small amount of sealant around all of the connections for the new system. This serves two purposes...one, it makes it a completely closed system, where nothing can get sucked in around the edge of the seals. Two, in sealing off any possible leaks, you now get better suction straight through the filter. I hope to have mine this week. Ordered it from Gravana about 10 days ago.
