i have a 95 powerstroke f-250 it has 211k miles on it i just did an oil change about a week to a week and a half ago but somehow it has leaked almost a gallon of oil between now and then. i usually park in the grass so i have not noticed it but i parked in the driveway last night and the was about a 6inch puddle under it this morning. im not sure where its coming from and thats the problem, it doesnt appear to be coming from the pan or oil filter but it also doesnt appear to be leaking from anywhere else ive always had a constant VERY small leak from the pan nut but never enough to have to add oil between changes. if anyone has any ideas of how to find the source of the leak or any idea of what to do about this please let me know.
Ya you're gonna have to clean up top some and start it and see if you can find the leak. It's probably from up top, like william said. My bet is either the turbo pedestal or the plugs in the back of the heads.
If this is eng oil and not fuel,I had that prob, mine was where the dipstick enters the pan, there is a round metal pad that connects with a very large nut. there is an o-ring INSIDE the pan that goes bad. Sometimes tightening the nut will stop your leak, otherwise, you must replace the oring. This can be done without dropping the pan, but look up how to do it on this forum or pm me and I will see if I can find the link. good luck.
