Does the filler tube have an extension? If so, remove the extension, and replace the rubber o-ring or seal. Rubber tends to swell and expand, or crack with age, when exposed to engine oil.How can i repair an oil leak at the oil fill tube?
well usually the fill tube has an o ring at the end that comes in contact with the engine so if you replace that it could fix your problem right there but if you have removed the fill tube before and perhaps dropped it or bent it in some way it will never seal properly again also if you take it to the car wash and powerwash the spot where the tube meets the block(to get rid of any exess oil ) and then wait for it to dry completely you may be able to run a small bead fo gasket sealer around it. NOTE: this method requires total dryness and lack of oil in the area or the sealer will not stick
you can get some JB Weld and fix it or you can buy a new oil fill tube
Get some JB Weld(cold weld patch).
jb weld works wonders!
