On a IO470-N I have a oil pan that developed a leak in the bottom middle of the pan. The engine has been removed. Is this repairable? Is it magnesium? If not repairable can you provide a part number or source for a replacement. Thank you
The oil pan is aluminum and is weldable by a qualified person. I need the rest of the model and spec number to get the proper pan The P/N on a IO470N(25) is 655297 and gasket is 655546 I checked for one in stock and could not find any available. Aviall shows a 44 day lead time with no price listed.
This post caught my attention as I have been chasing down an oil leak on my IO-470N as well. I am very curious as to how a leak could develop in the middle of a solid piece of aluminum. Has a crack developed? I have focused my efforts on gaskets, the vernatherm on the front side, oil cooler and any other area that involves a gasket/seal or line to the engine case or oil sump.
