Just bought one at a Chevy dealer. RV stored a couple of miles away so will post P/N when I get a chance. Autozone had one as well.

My sensor is leaking. Probably knocked or removed and reset without sealer when they did my Banks headers.

New sensor come with a white thread sealant applied. Autozone web site has a really good installation description. They advise coating the threads with GM P/N 12346004 or equivalent if reinstalling old sensor. I'll apply rust inhibitor on oil dip stick.

Thanks to both of you for the help. Hufficon that looks right . I thought it was leaking at the wires turns out it was just loose and old sealer. Pulled it cleaned it up reinstalled with sealer and all is good.
Thank you for the help
