I have a big oil leak and cant find where it is at there is oil on top of my engine but the oil leaks down behind the motor any suggestions would be greatly appreciated . it is a 99 f250 powerstroke 7.3 thanks

 

Possibly turbo pedistal o rings. It's hard to say. Try to clean out the valley with some simple green and a garden hose, then see if you can tell where it is coming from.

 

sure its oil not the drain plug on your fuel bowl? the common leak is there where the Yellow handle is for the fuel drain. those leaks are starting in the Valey. clean the truck up. you can use Simple Green and just wash the Motor up.
than you can start it up and check for leaks. you can use shop towels and dry the valley up. this will make looking for leak hell of the diference.

If its alot of oil it may becoming from the non serviceable plug in the HPOP... Don't worry it is serviceable ! Do a search on it and se if thats where its coming from !

 

Welcome to FTE.

Do as said, clean the valley and find where the oil is coming from. Once you find where it's coming from, lets us know and we will help you fix it.
