I just completed my condition inspection and performing a runup before cowling it up. I didn't have any leaks at the usual places but I had oil on the #2 cylinder intake flange and drips down the intake pipe. I was able to tighten the flange bolts just a little. There was no oil on the cylinder or anywhere else around the area. I know the propeller blast can throw oil all around but that intake flange is behind my air intake box. The valve cover gasket looks dry as well as the oil drain from the valve box.
Why would there be any oil at the intake flange to leak out regardless of the gasket condition?
Any ideas of where I should look?
