sturges. Devcon makes excellent products for various types of repairs. One of them is, Devcon Plastic Steel Putty, which has good resistance to oil, gas and other things. I have used JB Weld, but not in a case where it is exposed to oil, so I don't know if it is resistant or not. I should read JB instructions some day.
