my f450 superduty has a steady drip oil leak that appears to be coming from the base of the dipstik or around the hexagon fitting attached to the oil pan where the dipstik goes in the pan.are there o rings in this area tahat could be leaking?the engine is a powerstroke
Very important that you be careful with the inside of the pan half of the fitting. You can unbolt the dipstick and get it ready to pull out of the pan fitting but don't pull the stick until you get ahold of the through-pan fitting with a light touch with vice-grips or wire or tape or a wire-tie. When I undid and pulled the dipstick my nut fell of the outside and my inside part fell into the pan. You pretty much need to pull the pan to get the fitting out and put the new one on the inside of the pan. If you're careful and you keep a good hold on the fitting you can clean it all up with brake kleen and the slip a new o-ring into the inside of the pan by just going down the fitting and through the hole and into place then applying the gray sticky glue. Great stuff. It will hold the fitting and keep it from leaking with a new o-ring.
well i own a welding buissness so worst case i will weld the fitting to the pan guaranteed never to leak again
thanks everyone im going to try and do it the right way first but i have a backup plan if something goes wrong
You can relpace the inner o-ring without removing the pan. It just take alittle time and patience.
First remove the starter,then remove the dipstick tube(upper), clean the adapter off with brake clean, then (most important) using a coat hanger, bend a small V at the bottom of the hanger and push it into the dipstick adapter leaving enough of the hanger to tie to the frame of the truck (check that is the V is inside of the adapter and won't pull out easily, trust me on this! ) Remove the outside nut, clean the adapter off again(inside the pan and outside the pan), change out the o-ring (put alittle silicone on the new o-ring so it stays inplace), CAREFULLY reinstall the outside nut (very easy to cross thread, if you are trying to hurry!)fight to remove the hanger you pushed into the adapter, reinstall upper dipstick tube. Drain oil & brake clean mixture, change filter, refill oil, start truck check for leaks !
To let you know the kit form International cost about $85.00. I know cause I just ordered one. I haven't done it yet but sounds like it will be a learning experience. Good luck on yours
Gotta work on my dipstick flange leak this weekend and am just trying to get prepared with a few questions first. When removing the dipstick tube, does it just pull out or screw out of the adaptor? If using the International kit with the gasket that Fat Diesel had pictures of a while back, does the gasket go on the flange on the inside of the pan or outside of the pan?
ok i took the easy way out brake cleaner sandpaper and rtv,the leak stopped.no doubt its a temporary fix,i will get the kit from international for the next time it leaks.funny thing though i fix one oil leak another appears.i started with a leaking turbo then the dipstick and now its leaking pretty good from the back of the engine and the oil is running down between the starter and tranny.any ideas where thats coming from ive inspected the vc gaskets no leak there?
It's probably diesel leaking out of something up top and making its way to the back of the valley to the drain hole and then down the back of the block by the starter. It looks like dirty oil because it is cleaning off the engine as it goes. The fuel pump will do that and a few other things will do it, too. The fuel pump starts to leak out of the weephole when the pump nears the end of its life. It can leak for some time and still keep working.
