B bob888 Well Known Member Mar 4, 2022 #1 I have oil leaking out around the base of the filler neck on top of the engine. I believe all I need to do is replace the gasket but can't find a reference or part number. Anyone have the info? Thanks.

That would be order number 70457 https://www.aircraftspruce.com/catalog/eppages/lycominggaskets_07-03056.php I am not a mechanic but do have the part catalog for the IO-470. Best you get the one that matches your exact engine. Attachments Screen Shot 2022-03-04 at 10.53.40 PM.png 313.5 KB · Views: 44
