<VV> Leak at the base of the oil pressure switch

[gerg]

I bought that socket in 2001 and used it once. Somehow after moving cross country I was able to put my hand on it when I reworked the rear cover gasket and alternator adapter etc. last month. Still had the store plastic hanger stuck inn the 3/8" ratchet hole. 

Thanks,
